17----------------------------
18
19- [subset] Fixed AttributeError while traversing a color glyph's Paint graph when there is no
20  LayerList, which is optional (#2441).
21
224.28.0 (released 2021-11-05)
23----------------------------
24
25- Dropped support for EOL Python 3.6, require Python 3.7 (#2417).

27- [subset] Don't crash if optional ClipList and LayerList are ``None`` (empty) (#2424, 2439).
28- [OT-SVG] Removed support for old deprecated version 1 and embedded color palettes,
29  which were never officially part of the OpenType SVG spec. Upon compile, reuse offsets
30  to SVG documents that are identical (#2430).
31- [feaLib] Added support for Variable Feature File syntax. This is experimental and subject
32  to change until it is finalized in the Adobe FEA spec (#2432).
33- [unicodedata] Update Scripts/ScriptExtensions/Blocks to UnicodeData 14.0 (#2437).
34
354.27.1 (released 2021-09-23)
36----------------------------
37
38- [otlLib] Fixed error when chained contextual lookup builder overflows (#2404, #2411).
39- [bezierTools] Fixed two floating-point bugs: one when computing `t` for a point
40  lying on an almost horizontal/vertical line; another when computing the intersection
41  point between a curve and a line (#2413).
42
434.27.0 (released 2021-09-14)
44----------------------------
45
46- [ttLib/otTables] Cleaned up virtual GID handling: allow virtual GIDs in ``Coverage``
47  and ``ClassDef`` readers; removed unused ``allowVID`` argument from ``TTFont``
48  constructor, and ``requireReal`` argument in ``TTFont.getGlyphID`` method.
49  Make ``TTFont.setGlyphOrder`` clear reverse glyphOrder map, and assume ``glyphOrder``
50  internal attribute is never modified outside setGlyphOrder; added ``TTFont.getGlyphNameMany``
51  and ``getGlyphIDMany`` (#1536, #1654, #2334, #2398).
52- [py23] Dropped internal use of ``fontTools.py23`` module to fix deprecation warnings
53  in client code that imports from fontTools (#2234, #2399, #2400).
54- [subset] Fix subsetting COLRv1 clip boxes when font is loaded lazily (#2408).
55
564.26.2 (released 2021-08-09)
57----------------------------
58
59- [otTables] Added missing ``CompositeMode.PLUS`` operator (#2390).
60
614.26.1 (released 2021-08-03)
62----------------------------
63
64- [transform] Added ``transformVector`` and ``transformVectors`` methods to the
65  ``Transform`` class. Similar to ``transformPoint`` but ignore the translation
66  part (#2386).
67
684.26.0 (released 2021-08-03)
69----------------------------
70
71- [xmlWriter] Default to ``"\n"`` for ``newlinestr`` instead of platform-specific
72  ``os.linesep`` (#2384).
73- [otData] Define COLRv1 ClipList and ClipBox (#2379).
74- [removeOverlaps/instancer] Added --ignore-overlap-errors option to work around
75  Skia PathOps.Simplify bug (#2382, #2363, google/fonts#3365).
76- NOTE: This will be the last version to support Python 3.6. FontTools will require
77  Python 3.7 or above from the next release (#2350)
78
794.25.2 (released 2021-07-26)
80----------------------------
81
82- [COLRv1] Various changes to sync with the latest CORLv1 draft spec. In particular:
83  define COLR.VarIndexMap, remove/inline ColorIndex struct, add VarIndexBase to ``PaintVar*`` tables (#2372);
84  add reduced-precicion specialized transform Paints;
85  define Angle as fraction of half circle encoded as F2Dot14;
86  use FWORD (int16) for all Paint center coordinates;
87  change PaintTransform to have an offset to Affine2x3;
88- [ttLib] when importing XML, only set sfntVersion if the font has no reader and is empty (#2376)
89
904.25.1 (released 2021-07-16)
91----------------------------
92
93- [ttGlyphPen] Fixed bug in ``TTGlyphPointPen``, whereby open contours (i.e. starting
94  with segmentType "move") would throw ``NotImplementedError``. They are now treated
95  as if they are closed, like with the ``TTGlyphPen`` (#2364, #2366).
96
974.25.0 (released 2021-07-05)
98----------------------------
99
100- [tfmLib] Added new library for parsing TeX Font Metric (TFM) files (#2354).
101- [TupleVariation] Make shared tuples order deterministic on python < 3.7 where
102  Counter (subclass of dict) doesn't remember insertion order (#2351, #2353).
103- [otData] Renamed COLRv1 structs to remove 'v1' suffix and match the updated draft
104  spec: 'LayerV1List' -> 'LayerList', 'BaseGlyphV1List' -> 'BaseGlyphList',
105  'BaseGlyphV1Record' -> 'BaseGlyphPaintRecord' (#2346).
106  Added 8 new ``PaintScale*`` tables: with/without centers, uniform vs non-uniform.
107  Added ``*AroundCenter`` variants to ``PaintRotate`` and ``PaintSkew``: the default
108  versions no longer have centerX/Y, but default to origin.
109  ``PaintRotate``, ``PaintSkew`` and ``PaintComposite`` formats were re-numbered.
110  NOTE: these are breaking changes; clients using the experimental COLRv1 API will
111  have to be updated (#2348).
112- [pointPens] Allow ``GuessSmoothPointPen`` to accept a tolerance. Fixed call to
113  ``math.atan2`` with x/y parameters inverted. Sync the code with fontPens (#2344).
114- [post] Fixed parsing ``post`` table format 2.0 when it contains extra garbage
115  at the end of the stringData array (#2314).
116- [subset] drop empty features unless 'size' with FeatureParams table (#2324).
117- [otlLib] Added ``otlLib.optimize`` module; added GPOS compaction algorithm.
118  The compaction can be run on existing fonts with ``fonttools otlLib.optimize``
119  or using the snippet ``compact_gpos.py``. There's experimental support for
120  compacting fonts at compilation time using an environment variable, but that
121  might be removed later (#2326).
122
1234.24.4 (released 2021-05-25)
124----------------------------
125
126- [subset/instancer] Fixed ``AttributeError`` when instantiating a VF that
127  contains GPOS ValueRecords with ``Device`` tables but without the respective
128  non-Device values (e.g. ``XAdvDevice`` without ``XAdvance``). When not
129  explicitly set, the latter are assumed to be 0 (#2323).
130
1314.24.3 (released 2021-05-20)
132----------------------------
133
134- [otTables] Fixed ``AttributeError`` in methods that split LigatureSubst,
135  MultipleSubst and AlternateSubst subtables when an offset overflow occurs.
136  The ``Format`` attribute was removed in v4.22.0 (#2319).
137
1384.24.2 (released 2021-05-20)
139----------------------------
140
141- [ttGlyphPen] Fixed typing annotation of TTGlyphPen glyphSet parameter (#2315).
142- Fixed two instances of DeprecationWarning: invalid escape sequence (#2311).
143
1444.24.1 (released 2021-05-20)
145----------------------------
146
147- [subset] Fixed AttributeError when SinglePos subtable has None Value (ValueFormat 0)
148  (#2312, #2313).
149
1504.24.0 (released 2021-05-17)
151----------------------------
152
153- [pens] Add ``ttGlyphPen.TTGlyphPointPen`` similar to ``TTGlyphPen`` (#2205).
154
1554.23.1 (released 2021-05-14)
156----------------------------
157
158- [subset] Fix ``KeyError`` after subsetting ``COLR`` table that initially contains
159  both v0 and v1 color glyphs when the subset only requested v1 glyphs; we were
160  not pruning the v0 portion of the table (#2308).
161- [colorLib] Set ``LayerV1List`` attribute to ``None`` when empty, it's optional
162  in CORLv1 (#2308).
163
1644.23.0 (released 2021-05-13)
165----------------------------
166
167- [designspaceLib] Allow to use ``\\UNC`` absolute paths on Windows (#2299, #2306).
168- [varLib.merger] Fixed bug where ``VarLibMergeError`` was raised with incorrect
169  parameters (#2300).
170- [feaLib] Allow substituting a glyph class with ``NULL`` to delete multiple glyphs
171  (#2303).
172- [glyf] Fixed ``NameError`` exception in ``getPhantomPoints`` (#2295, #2305).
173- [removeOverlaps] Retry pathops.simplify after rounding path coordinates to integers
174  if it fails the first time using floats, to work around a rare and hard to debug
175  Skia bug (#2288).
176- [varLib] Added support for building, reading, writing and optimizing 32-bit
177  ``ItemVariationStore`` as used in COLRv1 table (#2285).
178- [otBase/otConverters] Add array readers/writers for int types (#2285).
179- [feaLib] Allow more than one lookahead glyph/class in contextual positioning with
180  "value at end" (#2293, #2294).
181- [COLRv1] Default varIdx should be 0xFFFFFFFF (#2297, #2298).
182- [pens] Make RecordingPointPen actually pass on identifiers; replace asserts with
183  explicit ``PenError`` exception (#2284).
184- [mutator] Round lsb for CF2 fonts as well (#2286).
185
1864.22.1 (released 2021-04-26)
187----------------------------
188
189- [feaLib] Skip references to named lookups if the lookup block definition
190  is empty, similarly to makeotf. This also fixes an ``AttributeError`` while
191  generating ``aalt`` feature (#2276, #2277).
192- [subset] Fixed bug with ``--no-hinting`` implementation for Device tables (#2272,
193  #2275). The previous code was alwyas dropping Device tables if no-hinting was
194  requested, but some Device tables (DeltaFormat=0x8000) are also used to encode
195  variation indices and need to be retained.
196- [otBase] Fixed bug in getting the ValueRecordSize when decompiling ``MVAR``
197  table with ``lazy=True`` (#2273, #2274).
198- [varLib/glyf/gvar] Optimized and simplified ``GlyphCoordinates`` and
199  ``TupleVariation`` classes, use ``bytearray`` where possible, refactored
200  phantom-points calculations. We measured about 30% speedup in total time
201  of loading master ttfs, building gvar, and saving (#2261, #2266).
202- [subset] Fixed ``AssertionError`` while pruning unused CPAL palettes when
203  ``0xFFFF`` is present (#2257, #2259).
204
2054.22.0 (released 2021-04-01)
206----------------------------
207
208- [ttLib] Remove .Format from Coverage, ClassDef, SingleSubst, LigatureSubst,
209  AlternateSubst, MultipleSubst (#2238).
210  ATTENTION: This will change your TTX dumps!
211- [misc.arrayTools] move Vector to its own submodule, and rewrite as a tuple
212  subclass (#2201).
213- [docs] Added a terminology section for varLib (#2209).
214- [varLib] Move rounding to VariationModel, to avoid error accumulation from
215  multiple deltas (#2214)
216- [varLib] Explain merge errors in more human-friendly terms (#2223, #2226)
217- [otlLib] Correct some documentation (#2225)
218- [varLib/otlLib] Allow merging into VariationFont without first saving GPOS
219  PairPos2 (#2229)
220- [subset] Improve PairPosFormat2 subsetting (#2221)
221- [ttLib] TTFont.save: create file on disk as late as possible (#2253)
222- [cffLib] Add missing CFF2 dict operators LanguageGroup and ExpansionFactor
223  (#2249)
224  ATTENTION: This will change your TTX dumps!
225
2264.21.1 (released 2021-02-26)
227----------------------------
228
229- [pens] Reverted breaking change that turned ``AbstractPen`` and ``AbstractPointPen``
230  into abstract base classes (#2164, #2198).
231
2324.21.0 (released 2021-02-26)
233----------------------------
234
235- [feaLib] Indent anchor statements in ``asFea()`` to make them more legible and
236  diff-able (#2193).
237- [pens] Turn ``AbstractPen`` and ``AbstractPointPen`` into abstract base classes
238  (#2164).
239- [feaLib] Added support for parsing and building ``STAT`` table from AFDKO feature
240  files (#2039).
241- [instancer] Added option to update name table of generated instance using ``STAT``
242  table's axis values (#2189).
243- [bezierTools] Added functions to compute bezier point-at-time, as well as line-line,
244  curve-line and curve-curve intersections (#2192).
245
2464.20.0 (released 2021-02-15)
247----------------------------
248
249- [COLRv1] Added ``unbuildColrV1`` to deconstruct COLRv1 otTables to raw json-able
250  data structure; it does the reverse of ``buildColrV1`` (#2171).
251- [feaLib] Allow ``sub X by NULL`` sequence to delete a glyph (#2170).
252- [arrayTools] Fixed ``Vector`` division (#2173).
253- [COLRv1] Define new ``PaintSweepGradient`` (#2172).
254- [otTables] Moved ``Paint.Format`` enum class outside of ``Paint`` class definition,
255  now named ``PaintFormat``. It was clashing with paint instance ``Format`` attribute
256  and thus was breaking lazy load of COLR table which relies on magic ``__getattr__``
257  (#2175).
258- [COLRv1] Replace hand-coded builder functions with otData-driven dynamic
259  implementation (#2181).
260- [COLRv1] Define additional static (non-variable) Paint formats (#2181).
261- [subset] Added support for subsetting COLR v1 and CPAL tables (#2174, #2177).
262- [fontBuilder] Allow ``setupFvar`` to optionally take ``designspaceLib.AxisDescriptor``
263  objects. Added new ``setupAvar`` method. Support localised names for axes and
264  named instances (#2185).
265
2664.19.1 (released 2021-01-28)
267----------------------------
268
269- [woff2] An initial off-curve point with an overlap flag now stays an off-curve
270  point after compression.
271
2724.19.0 (released 2021-01-25)
273----------------------------
274
275- [codecs] Handle ``errors`` parameter different from 'strict' for the custom
276  extended mac encodings (#2137, #2132).
277- [featureVars] Raise better error message when a script is missing the required
278  default language system (#2154).
279- [COLRv1] Avoid abrupt change caused by rounding ``PaintRadialGradient.c0`` when
280  the start circle almost touches the end circle's perimeter (#2148).
281- [COLRv1] Support building unlimited lists of paints as 255-ary trees of
282  ``PaintColrLayers`` tables (#2153).
283- [subset] Prune redundant format-12 cmap subtables when all non-BMP characters
284  are dropped (#2146).
285- [basePen] Raise ``MissingComponentError`` instead of bare ``KeyError`` when a
286  referenced component is missing (#2145).
287
2884.18.2 (released 2020-12-16)
289----------------------------
290
291- [COLRv1] Implemented ``PaintTranslate`` paint format (#2129).
292- [varLib.cff] Fixed unbound local variable error (#1787).
293- [otlLib] Don't crash when creating OpenType class definitions if some glyphs
294  occur more than once (#2125).
295
2964.18.1 (released 2020-12-09)
297----------------------------
298
299- [colorLib] Speed optimization for ``LayerV1ListBuilder`` (#2119).
300- [mutator] Fixed missing tab in ``interpolate_cff2_metrics`` (0957dc7a).
301
3024.18.0 (released 2020-12-04)
303----------------------------
304
305- [COLRv1] Update to latest draft: added ``PaintRotate`` and ``PaintSkew`` (#2118).
306- [woff2] Support new ``brotlicffi`` bindings for PyPy (#2117).
307- [glifLib] Added ``expectContentsFile`` parameter to ``GlyphSet``, for use when
308  reading existing UFOs, to comply with the specification stating that a
309  ``contents.plist`` file must exist in a glyph set (#2114).
310- [subset] Allow ``LangSys`` tags in ``--layout-scripts`` option (#2112). For example:
311  ``--layout-scripts=arab.dflt,arab.URD,latn``; this will keep ``DefaultLangSys``
312  and ``URD`` language for ``arab`` script, and all languages for ``latn`` script.
313- [varLib.interpolatable] Allow UFOs to be checked; report open paths, non existant
314  glyphs; add a ``--json`` option to produce a machine-readable list of
315  incompatibilities
316- [pens] Added ``QuartzPen`` to create ``CGPath`` from glyph outlines on macOS.
317  Requires pyobjc (#2107).
318- [feaLib] You can export ``FONTTOOLS_LOOKUP_DEBUGGING=1`` to enable feature file
319  debugging info stored in ``Debg`` table (#2106).
320- [otlLib] Build more efficient format 1 and format 2 contextual lookups whenever
321  possible (#2101).
322
3234.17.1 (released 2020-11-16)
324----------------------------
325
326- [colorLib] Fixed regression in 4.17.0 when building COLR v0 table; when color
327  layers are stored in UFO lib plist, we can't distinguish tuples from lists so
328  we need to accept either types (e5439eb9, googlefonts/ufo2ft/issues#426).
329
3304.17.0 (released 2020-11-12)
331----------------------------
332
333- [colorLib/otData] Updated to latest draft ``COLR`` v1 spec (#2092).
334- [svgLib] Fixed parsing error when arc commands' boolean flags are not separated
335  by space or comma (#2094).
336- [varLib] Interpret empty non-default glyphs as 'missing', if the default glyph is
337  not empty (#2082).
338- [feaLib.builder] Only stash lookup location for ``Debg`` if ``Builder.buildLookups_``
339  has cooperated (#2065, #2067).
340- [varLib] Fixed bug in VarStore optimizer (#2073, #2083).
341- [varLib] Add designspace lib key for custom feavar feature tag (#2080).
342- Add HashPointPen adapted from psautohint. With this pen, a hash value of a glyph
343  can be computed, which can later be used to detect glyph changes (#2005).
344
3454.16.1 (released 2020-10-05)
346----------------------------
347
348- [varLib.instancer] Fixed ``TypeError`` exception when instantiating a VF with
349  a GSUB table 1.1 in which ``FeatureVariations`` attribute is present but set to
350  ``None`` -- indicating that optional ``FeatureVariations`` is missing (#2077).
351- [glifLib] Make ``x`` and ``y`` attributes of the ``point`` element required
352  even when validation is turned off, and raise a meaningful ``GlifLibError``
353  message when that happens (#2075).
354
3554.16.0 (released 2020-09-30)
356----------------------------
357
358- [removeOverlaps] Added new module and ``removeOverlaps`` function that merges
359  overlapping contours and components in TrueType glyphs. It requires the
360  `skia-pathops <https://github.com/fonttools/skia-pathops>`__ module.
361  Note that removing overlaps invalidates the TrueType hinting (#2068).
362- [varLib.instancer] Added ``--remove-overlaps`` command-line option.
363  The ``overlap`` option in ``instantiateVariableFont`` now takes an ``OverlapMode``
364  enum: 0: KEEP_AND_DONT_SET_FLAGS, 1: KEEP_AND_SET_FLAGS (default), and 2: REMOVE.
365  The latter is equivalent to calling ``removeOverlaps`` on the generated static
366  instance. The option continues to accept ``bool`` value for backward compatibility.
367
368
3694.15.0 (released 2020-09-21)
370----------------------------
371
372- [plistlib] Added typing annotations to plistlib module. Set up mypy static
373  typechecker to run automatically on CI (#2061).
374- [ttLib] Implement private ``Debg`` table, a reverse-DNS namespaced JSON dict.
375- [feaLib] Optionally add an entry into the ``Debg`` table with the original
376  lookup name (if any), feature name / script / language combination (if any),
377  and original source filename and line location. Annotate the ttx output for
378  a lookup with the information from the Debg table (#2052).
379- [sfnt] Disabled checksum checking by default in ``SFNTReader`` (#2058).
380- [Docs] Document ``mtiLib`` module (#2027).
381- [varLib.interpolatable] Added checks for contour node count and operation type
382  of each node (#2054).
383- [ttLib] Added API to register custom table packer/unpacker classes (#2055).
384
3854.14.0 (released 2020-08-19)
386----------------------------
387
388- [feaLib] Allow anonymous classes in LookupFlags definitions (#2037).
389- [Docs] Better document DesignSpace rules processing order (#2041).
390- [ttLib] Fixed 21-year old bug in ``maxp.maxComponentDepth`` calculation (#2044,
391  #2045).
392- [varLib.models] Fixed misspelled argument name in CLI entry point (81d0042a).
393- [subset] When subsetting GSUB v1.1, fixed TypeError by checking whether the
394  optional FeatureVariations table is present (e63ecc5b).
395- [Snippets] Added snippet to show how to decompose glyphs in a TTF (#2030).
396- [otlLib] Generate GSUB type 5 and GPOS type 7 contextual lookups where appropriate
397  (#2016).
398
3994.13.0 (released 2020-07-10)
400----------------------------
401
402- [feaLib/otlLib] Moved lookup subtable builders from feaLib to otlLib; refactored
403  some common code (#2004, #2007).
404- [docs] Document otlLib module (#2009).
405- [glifLib] Fixed bug with some UFO .glif filenames clashing on case-insensitive
406  filesystems (#2001, #2002).
407- [colorLib] Updated COLRv1 implementation following changes in the draft spec:

412
413- [_n_a_m_e] Fixed error in ``addMultilingualName`` with one-character names.
414  Only attempt to recovered malformed UTF-16 data from a ``bytes`` string,
415  not from unicode ``str`` (#1997, #1998).
416
4174.12.0 (released 2020-06-09)
418----------------------------
419
420- [otlLib/varLib] Ensure that the ``AxisNameID`` in the ``STAT`` and ``fvar``
421  tables is grater than 255 as per OpenType spec (#1985, #1986).
422- [docs] Document more modules in ``fontTools.misc`` package: ``filenames``,
423  ``fixedTools``, ``intTools``, ``loggingTools``, ``macCreatorType``, ``macRes``,
424  ``plistlib`` (#1981).
425- [OS/2] Don't calculate whole sets of unicode codepoints, use faster and more memory
426  efficient ranges and bisect lookups (#1984).
427- [voltLib] Support writing back abstract syntax tree as VOLT data (#1983).
428- [voltLib] Accept DO_NOT_TOUCH_CMAP keyword (#1987).

432----------------------------
433
434- [feaLib] Introduced ``includeDir`` parameter on Parser and IncludingLexer to
435  explicitly specify the directory to search when ``include()`` statements are
436  encountered (#1973).
437- [ufoLib] Silently delete duplicate glyphs within the same kerning group when reading
438  groups (#1970).
439- [ttLib] Set version of COLR table when decompiling COLRv1 (commit 9d8a7e2).
440
4414.10.2 (released 2020-05-20)
442----------------------------
443
444- [sfnt] Fixed ``NameError: SimpleNamespace`` while reading TTC header. The regression
445  was introduced with 4.10.1 after removing ``py23`` star import.
446
4474.10.1 (released 2020-05-19)
448----------------------------
449
450- [sfnt] Make ``SFNTReader`` pickleable even when TTFont is loaded with lazy=True
451  option and thus keeps a reference to an external file (#1962, #1967).
452- [feaLib.ast] Restore backward compatibility (broken in 4.10 with #1905) for
453  ``ChainContextPosStatement`` and ``ChainContextSubstStatement`` classes.
454  Make them accept either list of lookups or list of lists of lookups (#1961).

461----------------------------
462
463- [varLib] Allow feature variations to be active across the entire space (#1957).
464- [ufoLib] Added support for ``formatVersionMinor`` in UFO's ``fontinfo.plist`` and for
465  ``formatMinor`` attribute in GLIF file as discussed in unified-font-object/ufo-spec#78.
466  No changes in reading or writing UFOs until an upcoming (non-0) minor update of the
467  UFO specification is published (#1786).
468- [merge] Fixed merging fonts with different versions of ``OS/2`` table (#1865, #1952).

472- [feaLib] Support multiple lookups per glyph position (#1905).
473- [psCharStrings] Use inheritance to avoid repeated code in initializer (#1932).
474- [Doc] Improved documentation for the following modules: ``afmLib`` (#1933), ``agl``
475  (#1934), ``cffLib`` (#1935), ``cu2qu`` (#1937), ``encodings`` (#1940), ``feaLib``
476  (#1941), ``merge`` (#1949).
477- [Doc] Split off developer-centric info to new page, making front page of docs more
478  user-focused. List all utilities and sub-modules with brief descriptions.
479  Make README more concise and focused (#1914).
480- [otlLib] Add function to build STAT table from high-level description (#1926).
481- [ttLib._n_a_m_e] Add ``findMultilingualName()`` method (#1921).

485  Ensure all fonttools CLI tools have help documentation (#1948).
486- [ufoLib] Only write fontinfo.plist when there actually is content (#1911).
487
4884.9.0 (released 2020-04-29)
489---------------------------
490
491- [subset] Fixed subsetting of FeatureVariations table. The subsetter no longer drops
492  FeatureVariationRecords that have empty substitutions as that will keep the search
493  going and thus change the logic. It will only drop empty records that occur at the
494  end of the FeatureVariationRecords array (#1881).
495- [subset] Remove FeatureVariations table and downgrade GSUB/GPOS to version 0x10000
496  when FeatureVariations contain no FeatureVariationRecords after subsetting (#1903).
497- [agl] Add support for legacy Adobe Glyph List of glyph names in ``fontTools.agl``
498  (#1895).
499- [feaLib] Ignore superfluous script statements (#1883).
500- [feaLib] Hide traceback by default on ``fonttools feaLib`` command line.
501  Use ``--traceback`` option to show (#1898).
502- [feaLib] Check lookup index in chaining sub/pos lookups and print better error
503  message (#1896, #1897).
504- [feaLib] Fix building chained alt substitutions (#1902).
505- [Doc] Included all fontTools modules in the sphinx-generated documentation, and
506  published it to ReadTheDocs for continuous documentation of the fontTools project
507  (#1333). Check it out at https://fonttools.readthedocs.io/. Thanks to Chris Simpkins!
508- [transform] The ``Transform`` class is now subclass of ``typing.NamedTuple``. No
509  change in functionality (#1904).
510
511
5124.8.1 (released 2020-04-17)
513---------------------------
514
515- [feaLib] Fixed ``AttributeError: 'NoneType' has no attribute 'getAlternateGlyphs'``
516  when ``aalt`` feature references a chain contextual substitution lookup
517  (googlefonts/fontmake#648, #1878).
518
5194.8.0 (released 2020-04-16)
520---------------------------
521
522- [feaLib] If Parser is initialized without a ``glyphNames`` parameter, it cannot
523  distinguish between a glyph name containing an hyphen, or a range of glyph names;
524  instead of raising an error, it now interprets them as literal glyph names, while
525  also outputting a logging warning to alert user about the ambiguity (#1768, #1870).
526- [feaLib] When serializing AST to string, emit spaces around hyphens that denote
527  ranges. Also, fixed an issue with CID ranges when round-tripping AST->string->AST
528  (#1872).
529- [Snippets/otf2ttf] In otf2ttf.py script update LSB in hmtx to match xMin (#1873).
530- [colorLib] Added experimental support for building ``COLR`` v1 tables as per
531  the `colr-gradients-spec <https://github.com/googlefonts/colr-gradients-spec/blob/master/colr-gradients-spec.md>`__
532  draft proposal. **NOTE**: both the API and the XML dump of ``COLR`` v1 are
533  susceptible to change while the proposal is being discussed and formalized (#1822).
534
5354.7.0 (released 2020-04-03)
536---------------------------
537
538- [cu2qu] Added ``fontTools.cu2qu`` package, imported from the original
539  `cu2qu <https://github.com/googlefonts/cu2qu>`__ project. The ``cu2qu.pens`` module
540  was moved to ``fontTools.pens.cu2quPen``. The optional cu2qu extension module
541  can be compiled by installing `Cython <https://cython.org/>`__ before installing
542  fonttools from source (i.e. git repo or sdist tarball). The wheel package that
543  is published on PyPI (i.e. the one ``pip`` downloads, unless ``--no-binary``
544  option is used), will continue to be pure-Python for now (#1868).
545
5464.6.0 (released 2020-03-24)
547---------------------------
548
549- [varLib] Added support for building variable ``BASE`` table version 1.1 (#1858).
550- [CPAL] Added ``fromRGBA`` method to ``Color`` class (#1861).
551
552
5534.5.0 (released 2020-03-20)
554---------------------------
555
556- [designspaceLib] Added ``add{Axis,Source,Instance,Rule}Descriptor`` methods to
557  ``DesignSpaceDocument`` class, to initialize new descriptor objects using keyword
558  arguments, and at the same time append them to the current document (#1860).
559- [unicodedata] Update to Unicode 13.0 (#1859).
560
5614.4.3 (released 2020-03-13)
562---------------------------
563
564- [varLib] Always build ``gvar`` table for TrueType-flavored Variable Fonts,
565  even if it contains no variation data. The table is required according to
566  the OpenType spec (#1855, #1857).
567
5684.4.2 (released 2020-03-12)
569---------------------------
570
571- [ttx] Annotate ``LookupFlag`` in XML dump with comment explaining what bits
572  are set and what they mean (#1850).
573- [feaLib] Added more descriptive message to ``IncludedFeaNotFound`` error (#1842).
574
5754.4.1 (released 2020-02-26)
576---------------------------
577
578- [woff2] Skip normalizing ``glyf`` and ``loca`` tables if these are missing from
579  a font (e.g. in NotoColorEmoji using ``CBDT/CBLC`` tables).
580- [timeTools] Use non-localized date parsing in ``timestampFromString``, to fix
581  error when non-English ``LC_TIME`` locale is set (#1838, #1839).
582- [fontBuilder] Make sure the CFF table generated by fontBuilder can be used by varLib
583  without having to compile and decompile the table first. This was breaking in
584  converting the CFF table to CFF2 due to some unset attributes (#1836).
585
5864.4.0 (released 2020-02-18)
587---------------------------
588
589- [colorLib] Added ``fontTools.colorLib.builder`` module, initially with ``buildCOLR``
590  and ``buildCPAL`` public functions. More color font formats will follow (#1827).
591- [fontBuilder] Added ``setupCOLR`` and ``setupCPAL`` methods (#1826).
592- [ttGlyphPen] Quantize ``GlyphComponent.transform`` floats to ``F2Dot14`` to fix
593  round-trip issue when computing bounding boxes of transformed components (#1830).
594- [glyf] If a component uses reference points (``firstPt`` and ``secondPt``) for
595  alignment (instead of X and Y offsets), compute the effective translation offset
596  *after* having applied any transform (#1831).
597- [glyf] When all glyphs have zero contours, compile ``glyf`` table data as a single
598  null byte in order to pass validation by OTS and Windows (#1829).
599- [feaLib] Parsing feature code now ensures that referenced glyph names are part of
600  the known glyph set, unless a glyph set was not provided.
601- [varLib] When filling in the default axis value for a missing location of a source or
602  instance, correctly map the value forward.
603- [varLib] The avar table can now contain mapping output values that are greater than
604  OR EQUAL to the preceeding value, as the avar specification allows this.
605- [varLib] The errors of the module are now ordered hierarchically below VarLibError.
606  See #1821.
607
6084.3.0 (released 2020-02-03)
609---------------------------
610
611- [EBLC/CBLC] Fixed incorrect padding length calculation for Format 3 IndexSubTable
612  (#1817, #1818).
613- [varLib] Fixed error when merging OTL tables and TTFonts were loaded as ``lazy=True``
614  (#1808, #1809).
615- [varLib] Allow to use master fonts containing ``CFF2`` table when building VF (#1816).
616- [ttLib] Make ``recalcBBoxes`` option work also with ``CFF2`` table (#1816).
617- [feaLib] Don't reset ``lookupflag`` in lookups defined inside feature blocks.
618  They will now inherit the current ``lookupflag`` of the feature. This is what
619  Adobe ``makeotf`` also does in this case (#1815).
620- [feaLib] Fixed bug with mixed single/multiple substitutions. If a single substitution
621  involved a glyph class, we were incorrectly using only the first glyph in the class
622  (#1814).
623
6244.2.5 (released 2020-01-29)
625---------------------------
626
627- [feaLib] Do not fail on duplicate multiple substitutions, only warn (#1811).
628- [subset] Optimize SinglePos subtables to Format 1 if all ValueRecords are the same
629  (#1802).
630
6314.2.4 (released 2020-01-09)
632---------------------------
633
634- [unicodedata] Update RTL_SCRIPTS for Unicode 11 and 12.
635
6364.2.3 (released 2020-01-07)
637---------------------------
638
639- [otTables] Fixed bug when splitting `MarkBasePos` subtables as offsets overflow.
640  The mark class values in the split subtable were not being updated, leading to
641  invalid mark-base attachments (#1797, googlefonts/noto-source#145).
642- [feaLib] Only log a warning instead of error when features contain duplicate
643  substitutions (#1767).
644- [glifLib] Strip XML comments when parsing with lxml (#1784, #1785).
645
6464.2.2 (released 2019-12-12)
647---------------------------
648
649- [subset] Fixed issue with subsetting FeatureVariations table when the index
650  of features changes as features get dropped. The feature index need to be
651  remapped to point to index of the remaining features (#1777, #1782).
652- [fontBuilder] Added `addFeatureVariations` method to `FontBuilder` class. This
653  is a shorthand for calling `featureVars.addFeatureVariations` on the builder's
654  TTFont object (#1781).
655- [glyf] Fixed the flags bug in glyph.drawPoints() like we did for glyph.draw()
656  (#1771, #1774).
657
6584.2.1 (released 2019-12-06)
659---------------------------
660
661- [glyf] Use the ``flagOnCurve`` bit mask in ``glyph.draw()``, so that we ignore
662  the ``overlap`` flag that may be set when instantiating variable fonts (#1771).
663
6644.2.0 (released 2019-11-28)
665---------------------------
666
667- [pens] Added the following pens:
668
669  * ``roundingPen.RoundingPen``: filter pen that rounds coordinates and components'
670    offsets to integer;
671  * ``roundingPen.RoundingPointPen``: like the above, but using PointPen protocol.
672  * ``filterPen.FilterPointPen``: base class for filter point pens;
673  * ``transformPen.TransformPointPen``: filter point pen to apply affine transform;
674  * ``recordingPen.RecordingPointPen``: records and replays point-pen commands.
675
676- [ttGlyphPen] Always round float coordinates and component offsets to integers
677  (#1763).
678- [ufoLib] When converting kerning groups from UFO2 to UFO3, avoid confusing
679  groups with the same name as one of the glyphs (#1761, #1762,
680  unified-font-object/ufo-spec#98).
681
6824.1.0 (released 2019-11-18)
683---------------------------
684
685- [instancer] Implemented restricting axis ranges (level 3 partial instancing).
686  You can now pass ``{axis_tag: (min, max)}`` tuples as input to the
687  ``instantiateVariableFont`` function. Note that changing the default axis
688  position is not supported yet. The command-line script also accepts axis ranges
689  in the form of colon-separated float values, e.g. ``wght=400:700`` (#1753, #1537).
690- [instancer] Never drop STAT ``DesignAxis`` records, but only prune out-of-range
691  ``AxisValue`` records.
692- [otBase/otTables] Enforce that VarStore.RegionAxisCount == fvar.axisCount, even
693  when regions list is empty to appease OTS < v8.0 (#1752).
694- [designspaceLib] Defined new ``processing`` attribute for ``<rules>`` element,
695  with values "first" or "last", plus other editorial changes to DesignSpace
696  specification. Bumped format version to 4.1 (#1750).
697- [varLib] Improved error message when masters' glyph orders do not match (#1758,
698  #1759).
699- [featureVars] Allow to specify custom feature tag in ``addFeatureVariations``;
700  allow said feature to already exist, in which case we append new lookup indices
701  to existing features. Implemented ``<rules>`` attribute ``processing`` according to
702  DesignSpace specification update in #1750. Depending on this flag, we generate
703  either an 'rvrn' (always processed first) or a 'rclt' feature (follows lookup order,
704  therefore last) (#1747, #1625, #1371).
705- [ttCollection] Added support for context manager auto-closing via ``with`` statement
706  like with ``TTFont`` (#1751).
707- [unicodedata] Require unicodedata2 >= 12.1.0.
708- [py2.py3] Removed yet more PY2 vestiges (#1743).
709- [_n_a_m_e] Fixed issue when comparing NameRecords with different string types (#1742).
710- [fixedTools] Changed ``fixedToFloat`` to not do any rounding but simply return
711  ``value / (1 << precisionBits)``. Added ``floatToFixedToStr`` and
712  ``strToFixedToFloat`` functions to be used when loading from or dumping to XML.
713  Fixed values (e.g. fvar axes and instance coordinates, avar mappings, etc.) are
714  are now stored as un-rounded decimal floats upon decompiling (#1740, #737).
715- [feaLib] Fixed handling of multiple ``LigatureCaret`` statements for the same glyph.
716  Only the first rule per glyph is used, additional ones are ignored (#1733).
717
7184.0.2 (released 2019-09-26)
719---------------------------
720
721- [voltLib] Added support for ``ALL`` and ``NONE`` in ``PROCESS_MARKS`` (#1732).
722- [Silf] Fixed issue in ``Silf`` table compilation and decompilation regarding str vs
723  bytes in python3 (#1728).
724- [merge] Handle duplicate glyph names better: instead of appending font index to
725  all glyph names, use similar code like we use in ``post`` and ``CFF`` tables (#1729).
726
7274.0.1 (released 2019-09-11)
728---------------------------
729
730- [otTables] Support fixing offset overflows in ``MultipleSubst`` lookup subtables
731  (#1706).
732- [subset] Prune empty strikes in ``EBDT`` and ``CBDT`` table data (#1698, #1633).
733- [pens] Fixed issue in ``PointToSegmentPen`` when last point of closed contour has
734  same coordinates as the starting point and was incorrectly dropped (#1720).
735- [Graphite] Fixed ``Sill`` table output to pass OTS (#1705).
736- [name] Added ``removeNames`` method to ``table__n_a_m_e`` class (#1719).
737- [ttLib] Added aliases for renamed entries ``ascender`` and ``descender`` in
738  ``hhea`` table (#1715).
739
7404.0.0 (released 2019-08-22)
741---------------------------
742
743- NOTE: The v4.x version series only supports Python 3.6 or greater. You can keep
744  using fonttools 3.x if you need support for Python 2.
745- [py23] Removed all the python2-only code since it is no longer reachable, thus
746  unused; only the Python3 symbols were kept, but these are no-op. The module is now
747  DEPRECATED and will removed in the future.
748- [ttLib] Fixed UnboundLocalError for empty loca/glyph tables (#1680). Also, allow
749  the glyf table to be incomplete when dumping to XML (#1681).
750- [varLib.models] Fixed KeyError while sorting masters and there are no on-axis for
751  a given axis (38a8eb0e).
752- [cffLib] Make sure glyph names are unique (#1699).
753- [feaLib] Fix feature parser to correctly handle octal numbers (#1700).
754
7553.44.0 (released 2019-08-02)
756----------------------------
757
758- NOTE: This is the last scheduled release to support Python 2.7. The upcoming fonttools
759  v4.x series is going to require Python 3.6 or greater.
760- [varLib] Added new ``varLib.instancer`` module for partially instantiating variable
761  fonts. This extends (and will eventually replace) ``varLib.mutator`` module, as
762  it allows to create not just full static instances from a variable font, but also
763  "partial" or "less variable" fonts where some of the axes are dropped or
764  instantiated at a particular value.
765  Also available from the command-line as `fonttools varLib.instancer --help`
766  (#1537, #1628).
767- [cffLib] Added support for ``FDSelect`` format 4 (#1677).
768- [subset] Added support for subsetting ``sbix`` (Apple bitmap color font) table.
769- [t1Lib] Fixed issue parsing ``eexec`` section in Type1 fonts when whitespace
770  characters are interspersed among the trailing zeros (#1676).
771- [cffLib.specializer] Fixed bug in ``programToCommands`` with CFF2 charstrings (#1669).
772
7733.43.2 (released 2019-07-10)
774----------------------------
775
776- [featureVars] Fixed region-merging code on python3 (#1659).
777- [varLib.cff] Fixed merging of sparse PrivateDict items (#1653).
778
7793.43.1 (released 2019-06-19)
780----------------------------
781
782- [subset] Fixed regression when passing ``--flavor=woff2`` option with an input font
783  that was already compressed as WOFF 1.0 (#1650).
784
7853.43.0 (released 2019-06-18)
786----------------------------
787
788- [woff2] Added support for compressing/decompressing WOFF2 fonts with non-transformed
789  ``glyf`` and ``loca`` tables, as well as with transformed ``hmtx`` table.
790  Removed ``Snippets/woff2_compress.py`` and ``Snippets/woff2_decompress.py`` scripts,
791  and replaced them with a new console entry point ``fonttools ttLib.woff2``
792  that provides two sub-commands ``compress`` and ``decompress``.
793- [varLib.cff] Fixed bug when merging CFF2 ``PrivateDicts``. The ``PrivateDict``
794  data from the first region font was incorrecty used for all subsequent fonts.
795  The bug would only affect variable CFF2 fonts with hinting (#1643, #1644).
796  Also, fixed a merging bug when VF masters have no blends or marking glyphs (#1632,
797  #1642).
798- [loggingTools] Removed unused backport of ``LastResortLogger`` class.

1001
1002- [psCharStrings] In ``encodeFloat`` function, use float's "general format" with
1003  8 digits of precision (i.e. ``%8g``) instead of ``str()``. This works around
1004  a macOS rendering issue when real numbers in CFF table are too long, and
1005  also makes sure that floats are encoded with the same precision in python 2.7
1006  and 3.x (#1430, googlei18n/ufo2ft#306).
1007- [_n_a_m_e/fontBuilder] Make ``_n_a_m_e_table.addMultilingualName`` also add
1008  Macintosh (platformID=1) names by default. Added options to ``FontBuilder``

1010  (#1359, #1431).
1011- [varLib] Make ``build`` optionally accept a ``DesignSpaceDocument`` object,
1012  instead of a designspace file path. The caller can now set the ``font``
1013  attribute of designspace's sources to a TTFont object, thus allowing to
1014  skip filenames manipulation altogether (#1416, #1425).
1015- [sfnt] Allow SFNTReader objects to be deep-copied.
1016- Require typing>=3.6.4 on py27 to fix issue with singledispatch (#1423).

1043  ``FontMatrix`` automatically from unitsPerEm.
1044- [plistLib] Accept the more general ``collections.Mapping`` instead of the
1045  specific ``dict`` class to support custom data classes that should serialize
1046  to dictionaries.
1047
10483.33.0 (released 2018-11-30)
1049----------------------------
1050- [subset] subsetter bug fix with variable fonts.
1051- [varLib.featureVar] Improve FeatureVariations generation with many rules.

1059----------------------------
1060
1061- [ufoLib] Make ``UFOWriter`` a subclass of ``UFOReader``, and use mixins
1062  for shared methods (#1344).
1063- [featureVars] Fixed normalization error when a condition's minimum/maximum
1064  attributes are missing in designspace ``<rule>`` (#1366).
1065- [setup.py] Added ``[plot]`` to extras, to optionally install ``matplotlib``,
1066  needed to use the ``fonTools.varLib.plot`` module.
1067- [varLib] Take total bounding box into account when resolving model (7ee81c8).
1068  If multiple axes have the same range ratio, cut across both (62003f4).
1069- [subset] Don't error if ``STAT`` has no ``AxisValue`` tables.
1070- [fontBuilder] Added a new submodule which contains a ``FontBuilder`` wrapper
1071  class around ``TTFont`` that makes it easier to create a working TTF or OTF
1072  font from scratch with code. NOTE: the API is still experimental and may
1073  change in future versions.
1074
10753.31.0 (released 2018-10-21)
1076----------------------------
1077
1078- [ufoLib] Merged the `ufoLib <https://github.com/unified-font-objects/ufoLib>`__
1079  master branch into a new ``fontTools.ufoLib`` package (#1335, #1095).

1081  Moved ``ufoLib.etree`` module to ``fontTools.misc.etree``.
1082  Moved ``ufoLib.plistlib`` module to ``fontTools.misc.plistlib``.
1083  To use the new ``fontTools.ufoLib`` module you need to install fonttools
1084  with the ``[ufo]`` extra, or you can manually install the required additional
1085  dependencies (cf. README.rst).

1098----------------------------
1099
1100- [feaLib] Skip building noop class PairPos subtables when Coverage is NULL
1101  (#1318).
1102- [ttx] Expose the previously reserved bit flag ``OVERLAP_SIMPLE`` of
1103  glyf table's contour points in the TTX dump. This is used in some
1104  implementations to specify a non-zero fill with overlapping contours (#1316).
1105- [ttLib] Added support for decompiling/compiling ``TS1C`` tables containing
1106  VTT sources for ``cvar`` variation table (#1310).
1107- [varLib] Use ``fontTools.designspaceLib`` to read DesignSpaceDocument. The
1108  ``fontTools.varLib.designspace`` module is now deprecated and will be removed
1109  in future versions. The presence of an explicit ``axes`` element is now
1110  required in order to build a variable font (#1224, #1313).

1112  element of DesignSpace document (#1240, #713, #1314).
1113- [subset] Added ``--no-layout-closure`` option to not expand the subset with
1114  the glyphs produced by OpenType layout features. Instead, OpenType features
1115  will be subset to only rules that are relevant to the otherwise-specified
1116  glyph set (#43, #1121).
1117
11183.29.1 (released 2018-09-10)
1119----------------------------
1120
1121- [feaLib] Fixed issue whereby lookups from DFLT/dflt were not included in the
1122  DFLT/non-dflt language systems (#1307).
1123- [graphite] Fixed issue on big-endian architectures (e.g. ppc64) (#1311).
1124- [subset] Added ``--layout-scripts`` option to add/exclude set of OpenType
1125  layout scripts that will be preserved. By default all scripts are retained
1126  (``'*'``) (#1303).
1127
11283.29.0 (released 2018-07-26)
1129----------------------------
1130
1131- [feaLib] In the OTL table builder, when the ``name`` table is excluded
1132  from the list of tables to be build, skip compiling ``featureNames`` blocks,
1133  as the records referenced in ``FeatureParams`` table don't exist (68951b7).
1134- [otBase] Try ``ExtensionLookup`` if other offset-overflow methods fail
1135  (05f95f0).
1136- [feaLib] Added support for explicit ``subtable;`` break statements in
1137  PairPos lookups; previously these were ignored (#1279, #1300, #1302).
1138- [cffLib.specializer] Make sure the stack depth does not exceed maxstack - 1,
1139  so that a subroutinizer can insert subroutine calls (#1301,
1140  https://github.com/googlei18n/ufo2ft/issues/266).
1141- [otTables] Added support for fixing offset overflow errors occurring inside
1142  ``MarkBasePos`` subtables (#1297).
1143- [subset] Write the default output file extension based on ``--flavor`` option,
1144  or the value of ``TTFont.sfntVersion`` (d7ac0ad).
1145- [unicodedata] Updated Blocks, Scripts and ScriptExtensions for Unicode 11
1146  (452c85e).
1147- [xmlWriter] Added context manager to XMLWriter class to autoclose file
1148  descriptor on exit (#1290).

1156----------------------------
1157
1158- [featureVars] Added experimental module to build ``FeatureVariations``
1159  tables. Still needs to be hooked up to ``varLib.build`` (#1240).
1160- [fixedTools] Added ``otRound`` to round floats to nearest integer towards
1161  positive Infinity. This is now used where we deal with visual data like X/Y
1162  coordinates, advance widths/heights, variation deltas, and similar (#1274,
1163  #1248).
1164- [subset] Improved GSUB closure memoize algorithm.
1165- [varLib.models] Fixed regression in model resolution (180124, #1269).
1166- [feaLib.ast] Fixed error when converting ``SubtableStatement`` to string

1170  (#1276, #1264).
1171- [py23/loggingTools] Don't automatically set ``logging.lastResort`` handler
1172  on py27. Moved ``LastResortLogger`` to the ``loggingTools`` module (#1277).

1182----------------------------
1183
1184- [designspaceLib] Added new ``conditionSet`` element to ``rule`` element in
1185  designspace document. Bumped ``format`` attribute to ``4.0`` (previously,
1186  it was formatted as an integer). Removed ``checkDefault``, ``checkAxes``
1187  methods, and any kind of guessing about the axes when the ``<axes>`` element
1188  is missing. The default master is expected at the intersection of all default
1189  values for each axis (#1254, #1255, #1267).
1190- [cffLib] Fixed issues when compiling CFF2 or converting from CFF when the
1191  font has an FDArray (#1211, #1271).
1192- [varLib] Avoid attempting to build ``cvar`` table when ``glyf`` table is not
1193  present, as is the case for CFF2 fonts.
1194- [subset] Handle None coverages in MarkGlyphSets; revert commit 02616ab that
1195  sets empty Coverage tables in MarkGlyphSets to None, to make OTS happy.
1196- [ttFont] Allow to build glyph order from ``maxp.numGlyphs`` when ``post`` or
1197  ``cmap`` are missing.
1198- [ttFont] Added ``__len__`` method to ``_TTGlyphSet``.
1199- [glyf] Ensure ``GlyphCoordinates`` never overflow signed shorts (#1230).
1200- [py23] Added alias for ``itertools.izip`` shadowing the built-in ``zip``.
1201- [loggingTools] Memoize ``log`` property of ``LogMixin`` class (fbab12).
1202- [ttx] Impoved test coverage (#1261).
1203- [Snippets] Addded script to append a suffix to all family names in a font.
1204- [varLib.plot] Make it work with matplotlib >= 2.1 (b38e2b).
1205
12063.26.0 (released 2018-05-03)
1207----------------------------
1208
1209- [designspace] Added a new optional ``layer`` attribute to the source element,
1210  and a corresponding ``layerName`` attribute to the ``SourceDescriptor``
1211  object (#1253).
1212  Added ``conditionset`` element to the ``rule`` element to the spec, but not
1213  implemented in designspace reader/writer yet (#1254).
1214- [varLib.models] Refine modeling one last time (0ecf5c5).
1215- [otBase] Fixed sharing of tables referred to by different offset sizes
1216  (795f2f9).
1217- [subset] Don't drop a GDEF that only has VarStore (fc819d6). Set to None
1218  empty Coverage tables in MarkGlyphSets (02616ab).
1219- [varLib]: Added ``--master-finder`` command-line option (#1249).
1220- [varLib.mutator] Prune fvar nameIDs from instance's name table (#1245).
1221- [otTables] Allow decompiling bad ClassDef tables with invalid format, with
1222  warning (#1236).
1223- [varLib] Make STAT v1.2 and reuse nameIDs from fvar table (#1242).
1224- [varLib.plot] Show master locations. Set axis limits to -1, +1.
1225- [subset] Handle HVAR direct mapping. Passthrough 'cvar'.
1226  Added ``--font-number`` command-line option for collections.
1227- [t1Lib] Allow a text encoding to be specified when parsing a Type 1 font
1228  (#1234). Added ``kind`` argument to T1Font constructor (c5c161c).
1229- [ttLib] Added context manager API to ``TTFont`` class, so it can be used in
1230  ``with`` statements to auto-close the file when exiting the context (#1232).
1231
12323.25.0 (released 2018-04-03)
1233----------------------------
1234
1235- [varLib] Improved support-resolution algorithm. Previously, the on-axis
1236  masters would always cut the space. They don't anymore. That's more
1237  consistent, and fixes the main issue Erik showed at TYPO Labs 2017.
1238  Any varfont built that had an unusual master configuration will change
1239  when rebuilt (42bef17, a523a697,
1240  https://github.com/googlei18n/fontmake/issues/264).
1241- [varLib.models] Added a ``main()`` entry point, that takes positions and
1242  prints model results.
1243- [varLib.plot] Added new module to plot a designspace's
1244  VariationModel. Requires ``matplotlib``.
1245- [varLib.mutator] Added -o option to specify output file path (2ef60fa).
1246- [otTables] Fixed IndexError while pruning of HVAR pre-write (6b6c34a).
1247- [varLib.models] Convert delta array to floats if values overflows signed
1248  short integer (0055f94).
1249
12503.24.2 (released 2018-03-26)
1251----------------------------
1252
1253- [otBase] Don't fail during ``ValueRecord`` copy if src has more items.
1254  We drop hinting in the subsetter by simply changing ValueFormat, without
1255  cleaning up the actual ValueRecords. This was causing assertion error if
1256  a variable font was subsetted without hinting and then passed directly to
1257  the mutator for instantiation without first it saving to disk.
1258
12593.24.1 (released 2018-03-06)
1260----------------------------
1261
1262- [varLib] Don't remap the same ``DeviceTable`` twice in VarStore optimizer
1263  (#1206).
1264- [varLib] Add ``--disable-iup`` option to ``fonttools varLib`` script,
1265  and a ``optimize=True`` keyword argument to ``varLib.build`` function,
1266  to optionally disable IUP optimization while building varfonts.
1267- [ttCollection] Fixed issue while decompiling ttc with python3 (#1207).
1268
12693.24.0 (released 2018-03-01)
1270----------------------------
1271
1272- [ttGlyphPen] Decompose composite glyphs if any components' transform is too
1273  large to fit a ``F2Dot14`` value, or clamp transform values that are
1274  (almost) equal to +2.0 to make them fit and avoid decomposing (#1200,
1275  #1204, #1205).
1276- [ttx] Added new ``-g`` option to dump glyphs from the ``glyf`` table
1277  splitted as individual ttx files (#153, #1035, #1132, #1202).
1278- Copied ``ufoLib.filenames`` module to ``fontTools.misc.filenames``, used
1279  for the ttx split-glyphs option (#1202).
1280- [feaLib] Added support for ``cvParameters`` blocks in Character Variant
1281  feautures ``cv01-cv99`` (#860, #1169).
1282- [Snippets] Added ``checksum.py`` script to generate/check SHA1 hash of
1283  ttx files (#1197).
1284- [varLib.mutator] Fixed issue while instantiating some variable fonts
1285  whereby the horizontal advance width computed from ``gvar`` phantom points
1286  could turn up to be negative (#1198).
1287- [varLib/subset] Fixed issue with subsetting GPOS variation data not
1288  picking up ``ValueRecord`` ``Device`` objects (54fd71f).
1289- [feaLib/voltLib] In all AST elements, the ``location`` is no longer a
1290  required positional argument, but an optional kewyord argument (defaults
1291  to ``None``). This will make it easier to construct feature AST from
1292  code (#1201).
1293
1294
12953.23.0 (released 2018-02-26)
1296----------------------------
1297
1298- [designspaceLib] Added an optional ``lib`` element to the designspace as a
1299  whole, as well as to the instance elements, to store arbitrary data in a
1300  property list dictionary, similar to the UFO's ``lib``. Added an optional
1301  ``font`` attribute to the ``SourceDescriptor``, to allow operating on
1302  in-memory font objects (#1175).
1303- [cffLib] Fixed issue with lazy-loading of attributes when attempting to
1304  set the CFF TopDict.Encoding (#1177, #1187).
1305- [ttx] Fixed regression introduced in 3.22.0 that affected the split tables
1306  ``-s`` option (#1188).
1307- [feaLib] Added ``IncludedFeaNotFound`` custom exception subclass, raised
1308  when an included feature file cannot be found (#1186).
1309- [otTables] Changed ``VarIdxMap`` to use glyph names internally instead of
1310  glyph indexes. The old ttx dumps of HVAR/VVAR tables that contain indexes
1311  can still be imported (21cbab8, 38a0ffb).
1312- [varLib] Implemented VarStore optimizer (#1184).
1313- [subset] Implemented pruning of GDEF VarStore, HVAR and MVAR (#1179).
1314- [sfnt] Restore backward compatiblity with ``numFonts`` attribute of
1315  ``SFNTReader`` object (#1181).
1316- [merge] Initial support for merging ``LangSysRecords`` (#1180).
1317- [ttCollection] don't seek(0) when writing to possibly unseekable strems.
1318- [subset] Keep all ``--name-IDs`` from 0 to 6 by default (#1170, #605, #114).
1319- [cffLib] Added ``width`` module to calculate optimal CFF default and
1320  nominal glyph widths.
1321- [varLib] Don’t fail if STAT already in the master fonts (#1166).
1322
13233.22.0 (released 2018-02-04)
1324----------------------------
1325
1326- [subset] Support subsetting ``endchar`` acting as ``seac``-like components
1327  in ``CFF`` (fixes #1162).
1328- [feaLib] Allow to build from pre-parsed ``ast.FeatureFile`` object.
1329  Added ``tables`` argument to only build some tables instead of all (#1159,
1330  #1163).
1331- [textTools] Replaced ``safeEval`` with ``ast.literal_eval`` (#1139).
1332- [feaLib] Added option to the parser to not resolve ``include`` statements
1333  (#1154).
1334- [ttLib] Added new ``ttCollection`` module to read/write TrueType and
1335  OpenType Collections. Exports a ``TTCollection`` class with a ``fonts``
1336  attribute containing a list of ``TTFont`` instances, the methods ``save``
1337  and ``saveXML``, plus some list-like methods. The ``importXML`` method is
1338  not implemented yet (#17).
1339- [unicodeadata] Added ``ot_tag_to_script`` function that converts from
1340  OpenType script tag to Unicode script code.
1341- Added new ``designspaceLib`` subpackage, originally from Erik Van Blokland's
1342  ``designSpaceDocument``: https://github.com/LettError/designSpaceDocument
1343  NOTE: this is not yet used internally by varLib, and the API may be subject
1344  to changes (#911, #1110, LettError/designSpaceDocument#28).
1345- Added new FontTools icon images (8ee7c32).
1346- [unicodedata] Added ``script_horizontal_direction`` function that returns
1347  either "LTR" or "RTL" given a unicode script code.
1348- [otConverters] Don't write descriptive name string as XML comment if the
1349  NameID value is 0 (== NULL) (#1151, #1152).
1350- [unicodedata] Add ``ot_tags_from_script`` function to get the list of
1351  OpenType script tags associated with unicode script code (#1150).
1352- [feaLib] Don't error when "enumerated" kern pairs conflict with preceding
1353  single pairs; emit warning and chose the first value (#1147, #1148).
1354- [loggingTools] In ``CapturingLogHandler.assertRegex`` method, match the
1355  fully formatted log message.
1356- [sbix] Fixed TypeError when concatenating str and bytes (#1154).
1357- [bezierTools] Implemented cusp support and removed ``approximate_fallback``
1358  arg in ``calcQuadraticArcLength``. Added ``calcCubicArcLength`` (#1142).
1359
13603.21.2 (released 2018-01-08)
1361----------------------------
1362
1363- [varLib] Fixed merging PairPos Format1/2 with missing subtables (#1125).
1364
13653.21.1 (released 2018-01-03)
1366----------------------------
1367
1368- [feaLib] Allow mixed single/multiple substitutions (#612)
1369- Added missing ``*.afm`` test assets to MAINFEST.in (#1137).
1370- Fixed dumping ``SVG`` tables containing color palettes (#1124).
1371
13723.21.0 (released 2017-12-18)
1373----------------------------
1374
1375- [cmap] when compiling format6 subtable, don't assume gid0 is always called
1376  '.notdef' (1e42224).
1377- [ot] Allow decompiling fonts with bad Coverage format number (1aafae8).
1378- Change FontTools licence to MIT (#1127).
1379- [post] Prune extra names already in standard Mac set (df1e8c7).
1380- [subset] Delete empty SubrsIndex after subsetting (#994, #1118).
1381- [varLib] Don't share points in cvar by default, as it currently fails on
1382  some browsers (#1113).
1383- [afmLib] Make poor old afmLib work on python3.
1384
13853.20.1 (released 2017-11-22)
1386----------------------------
1387
1388- [unicodedata] Fixed issue with ``script`` and ``script_extension`` functions
1389  returning inconsistent short vs long names. They both return the short four-
1390  letter script codes now. Added ``script_name`` and ``script_code`` functions
1391  to look up the long human-readable script name from the script code, and
1392  viceversa (#1109, #1111).
1393
13943.20.0 (released 2017-11-21)
1395----------------------------
1396
1397- [unicodedata] Addded new module ``fontTools.unicodedata`` which exports the
1398  same interface as the built-in ``unicodedata`` module, with the addition of
1399  a few functions that are missing from the latter, such as ``script``,
1400  ``script_extension`` and ``block``. Added a ``MetaTools/buildUCD.py`` script
1401  to download and parse data files from the Unicode Character Database and
1402  generate python modules containing lists of ranges and property values.
1403- [feaLib] Added ``__str__`` method to all ``ast`` elements (delegates to the
1404  ``asFea`` method).
1405- [feaLib] ``Parser`` constructor now accepts a ``glyphNames`` iterable
1406  instead of ``glyphMap`` dict. The latter still works but with a pending
1407  deprecation warning (#1104).
1408- [bezierTools] Added arc length calculation functions originally from
1409  ``pens.perimeterPen`` module (#1101).
1410- [varLib] Started generating STAT table (8af4309). Right now it just reflects
1411  the axes, and even that with certain limitations:
1412  * AxisOrdering is set to the order axes are defined,
1413  * Name-table entries are not shared with fvar.
1414- [py23] Added backports for ``redirect_stdout`` and ``redirect_stderr``
1415  context managers (#1097).
1416- [Graphite] Fixed some round-trip bugs (#1093).
1417
14183.19.0 (released 2017-11-06)
1419----------------------------
1420
1421- [varLib] Try set of used points instead of all points when testing whether to
1422  share points between tuples (#1090).
1423- [CFF2] Fixed issue with reading/writing PrivateDict BlueValues to TTX file.
1424  Read the commit message 8b02b5a and issue #1030 for more details.
1425  NOTE: this change invalidates all the TTX files containing CFF2 tables
1426  that where dumped with previous verisons of fonttools.
1427  CFF2 Subr items can have values on the stack after the last operator, thus
1428  a ``CFF2Subr`` class was added to accommodate this (#1091).
1429- [_k_e_r_n] Fixed compilation of AAT kern version=1.0 tables (#1089, #1094)
1430- [ttLib] Added getBestCmap() convenience method to TTFont class and cmap table
1431  class that returns a preferred Unicode cmap subtable given a list of options
1432  (#1092).
1433- [morx] Emit more meaningful subtable flags. Implement InsertionMorphAction
1434
14353.18.0 (released 2017-10-30)
1436----------------------------

1441- [reverseContourPen] Keep duplicate lineTo following a moveTo (#1080,
1442  https://github.com/googlei18n/cu2qu/issues/51).
1443- [varLib.mutator] Suport instantiation of GPOS, GDEF and MVAR (#1079).
1444- [sstruct] Fixed issue with ``unicode_literals`` and ``struct`` module in
1445  old versions of python 2.7 (#993).
1446
14473.17.0 (released 2017-10-16)
1448----------------------------
1449
1450- [svgPathPen] Added an ``SVGPathPen`` that translates segment pen commands
1451  into SVG path descriptions. Copied from Tal Leming's ``ufo2svg.svgPathPen``
1452  https://github.com/typesupply/ufo2svg/blob/d69f992/Lib/ufo2svg/svgPathPen.py
1453- [reverseContourPen] Added ``ReverseContourPen``, a filter pen that draws
1454  contours with the winding direction reversed, while keeping the starting
1455  point (#1071).
1456- [filterPen] Added ``ContourFilterPen`` to manipulate contours as a whole
1457  rather than segment by segment.
1458- [arrayTools] Added ``Vector`` class to apply math operations on an array
1459  of numbers, and ``pairwise`` function to loop over pairs of items in an
1460  iterable.
1461- [varLib] Added support for building and interpolation of ``cvar`` table
1462  (f874cf6, a25a401).
1463

1473- [varLib] Default to using axis "name" attribute if "labelname" element
1474  is missing (588f524).
1475- [merge] Added support for merging Script records. Remove unused features
1476  and lookups after merge (d802580, 556508b).
1477- Added ``fontTools.svgLib`` package. Includes a parser for SVG Paths that
1478  supports the Pen protocol (#1051). Also, added a snippet to convert SVG
1479  outlines to UFO GLIF (#1053).
1480- [AAT] Added support for ``ankr``, ``bsln``, ``mort``, ``morx``, ``gcid``,
1481  and ``cidg``.
1482- [subset] Implemented subsetting of ``prop``, ``opbd``, ``bsln``, ``lcar``.
1483
14843.15.1 (released 2017-08-18)
1485----------------------------
1486
1487- [otConverters] Implemented ``__add__`` and ``__radd__`` methods on
1488  ``otConverters._LazyList`` that decompile a lazy list before adding
1489  it to another list or ``_LazyList`` instance. Fixes an ``AttributeError``
1490  in the ``subset`` module when attempting to sum ``_LazyList`` objects
1491  (6ef48bd2, 1aef1683).
1492- [AAT] Support the `opbd` table with optical bounds (a47f6588).
1493- [AAT] Support `prop` table with glyph properties (d05617b4).
1494

14963.15.0 (released 2017-08-17)
1497----------------------------
1498
1499- [AAT] Added support for AAT lookups. The ``lcar`` table can be decompiled
1500  and recompiled; futher work needed to handle ``morx`` table (#1025).
1501- [subset] Keep (empty) DefaultLangSys for Script 'DFLT' (6eb807b5).
1502- [subset] Support GSUB/GPOS.FeatureVariations (fe01d87b).
1503- [varLib] In ``models.supportScalars``, ignore an axis when its peak value
1504  is 0 (fixes #1020).
1505- [varLib] Add default mappings to all axes in avar to fix rendering issue
1506  in some rasterizers (19c4b377, 04eacf13).
1507- [varLib] Flatten multiple tail PairPosFormat2 subtables before merging
1508  (c55ef525).
1509- [ttLib] Added support for recalculating font bounding box in ``CFF`` and
1510  ``head`` tables, and min/max values in ``hhea`` and ``vhea`` tables (#970).
1511
15123.14.0 (released 2017-07-31)
1513----------------------------
1514

1523  (c0d672ba).
1524- [cffLib] Allow to get TopDict by index as well as by name (dca96c9c).
1525- [cffLib] Removed global ``isCFF2`` state; use one set of classes for
1526  both CFF and CFF2, maintaining backward compatibility existing code (#1007).
1527- [cffLib] Deprecated maxstack operator, per OpenType spec update 1.8.1.
1528- [cffLib] Added missing default (-100) for UnderlinePosition (#983).
1529- [feaLib] Enable setting nameIDs greater than 255 (#1003).
1530- [varLib] Recalculate ValueFormat when merging SinglePos (#996).
1531- [varLib] Do not emit MVAR if there are no entries in the variation store
1532  (#987).
1533- [ttx] For ``-x`` option, pad with space if table tag length is < 4.
1534
15353.13.1 (released 2017-05-30)
1536----------------------------
1537
1538- [feaLib.builder] Removed duplicate lookups optimization. The original
1539  lookup order and semantics of the feature file are preserved (#976).
1540
15413.13.0 (released 2017-05-24)
1542----------------------------
1543
1544- [varLib.mutator] Implement IUP optimization (#969).
1545- [_g_l_y_f.GlyphCoordinates] Changed ``__bool__()`` semantics to match those
1546  of other iterables (e46f949). Removed ``__abs__()`` (3db5be2).
1547- [varLib.interpolate_layout] Added ``mapped`` keyword argument to
1548  ``interpolate_layout`` to allow disabling avar mapping: if False (default),
1549  the location is mapped using the map element of the axes in designspace file;
1550  if True, it is assumed that location is in designspace's internal space and
1551  no mapping is performed (#950, #975).
1552- [varLib.interpolate_layout] Import designspace-loading logic from varLib.
1553- [varLib] Fixed bug with recombining PairPosClass2 subtables (81498e5, #914).

1856-  [setup.py] remove undocumented/deprecated ``extra_path`` Distutils
1857   argument. This means that we no longer create a "FontTools" subfolder
1858   in site-packages containing the actual fontTools package, as well as
1859   the standalone xmlWriter and sstruct modules. The latter modules are
1860   also deprecated, and scheduled for removal in upcoming releases.
1861   Please change your import statements to point to from fontTools.misc
1862   import xmlWriter and from fontTools.misc import sstruct.
1863-  [scripts] Add a 'fonttools' command-line tool that simply runs
1864   ``fontTools.*`` sub-modules: e.g. ``fonttools ttx``,
1865   ``fonttools subset``, etc.

1986-------------------------
1987
1988-  Many years worth of fixes and features
1989
19902.0b2 (released 2002-??-??)
1991---------------------------
1992
1993-  Be "forgiving" when interpreting the maxp table version field:
1994   interpret any value as 1.0 if it's not 0.5. Fixes dumping of these
1995   GPL fonts: http://www.freebsd.org/cgi/pds.cgi?ports/chinese/wangttf
1996-  Fixed ttx -l: it turned out this part of the code didn't work with
1997   Python 2.2.1 and earlier. My bad to do most of my testing with a
1998   different version than I shipped TTX with :-(
1999-  Fixed bug in ClassDef format 1 subtable (Andreas Seidel bumped into
2000   this one).
2001
20022.0b1 (released 2002-09-10)
2003---------------------------
2004
2005-  Fixed embarrassing bug: the master checksum in the head table is now
2006   calculated correctly even on little-endian platforms (such as Intel).
2007-  Made the cmap format 4 compiler smarter: the binary data it creates
2008   is now more or less as compact as possible. TTX now makes more
2009   compact data than in any shipping font I've tested it with.
2010-  Dump glyph names as a separate "GlyphOrder" pseudo table as opposed
2011   to as part of the glyf table (obviously needed for CFF-OTF's).
2012-  Added proper support for the CFF table.
2013-  Don't barf on empty tables (questionable, but "there are font out
2014   there...")
2015-  When writing TT glyf data, align glyphs on 4-byte boundaries. This
2016   seems to be the current recommendation by MS. Also: don't barf on
2017   fonts which are already 4-byte aligned.
2018-  Windows installer contributed bu Adam Twardoch! Yay!
2019-  Changed the command line interface again, now by creating one new
2020   tool replacing the old ones: ttx It dumps and compiles, depending on
2021   input file types. The options have changed somewhat.
2022-  The -d option is back (output dir)
2023-  ttcompile's -i options is now called -m (as in "merge"), to avoid
2024   clash with dump's -i.
2025-  The -s option ("split tables") no longer creates a directory, but
2026   instead outputs a small .ttx file containing references to the
2027   individual table files. This is not a true link, it's a simple file
2028   name, and the referenced file should be in the same directory so
2029   ttcompile can find them.
2030-  compile no longer accepts a directory as input argument. Instead it
2031   can parse the new "mini-ttx" format as output by "ttx -s".
2032-  all arguments are input files
2033-  Renamed the command line programs and moved them to the Tools
2034   subdirectory. They are now installed by the setup.py install script.
2035-  Added OpenType support. BASE, GDEF, GPOS, GSUB and JSTF are (almost)
2036   fully supported. The XML output is not yet final, as I'm still
2037   considering to output certain subtables in a more human-friendly
2038   manner.
2039-  Fixed 'kern' table to correctly accept subtables it doesn't know
2040   about, as well as interpreting Apple's definition of the 'kern' table
2041   headers correctly.
2042-  Fixed bug where glyphnames were not calculated from 'cmap' if it was
2043   (one of the) first tables to be decompiled. More specifically: it
2044   cmap was the first to ask for a glyphID -> glyphName mapping.
2045-  Switched XML parsers: use expat instead of xmlproc. Should be faster.
2046-  Removed my UnicodeString object: I now require Python 2.0 or up,
2047   which has unicode support built in.
2048-  Removed assert in glyf table: redundant data at the end of the table
2049   is now ignored instead of raising an error. Should become a warning.
2050-  Fixed bug in hmtx/vmtx code that only occured if all advances were
2051   equal.
2052-  Fixed subtle bug in TT instruction disassembler.
2053-  Couple of fixes to the 'post' table.
2054-  Updated OS/2 table to latest spec.
2055
20561.0b1 (released 2001-08-10)
2057---------------------------
2058
2059-  Reorganized the command line interface for ttDump.py and
2060   ttCompile.py, they now behave more like "normal" command line tool,
2061   in that they accept multiple input files for batch processing.
2062-  ttDump.py and ttCompile.py don't silently override files anymore, but
2063   ask before doing so. Can be overridden by -f.
2064-  Added -d option to both ttDump.py and ttCompile.py.
2065-  Installation is now done with distutils. (Needs work for environments
2066   without compilers.)
2067-  Updated installation instructions.
2068-  Added some workarounds so as to handle certain buggy fonts more
2069   gracefully.
2070-  Updated Unicode table to Unicode 3.0 (Thanks Antoine!)
2071-  Included a Python script by Adam Twardoch that adds some useful stuff
2072   to the Windows registry.
2073-  Moved the project to SourceForge.
2074
20751.0a6 (released 2000-03-15)
2076---------------------------
2077
2078-  Big reorganization: made ttLib a subpackage of the new fontTools
2079   package, changed several module names. Called the entire suite
2080   "FontTools"
2081-  Added several submodules to fontTools, some new, some older.
2082-  Added experimental CFF/GPOS/GSUB support to ttLib, read-only (but XML
2083   dumping of GPOS/GSUB is for now disabled)
2084-  Fixed hdmx endian bug
2085-  Added -b option to ttCompile.py, it disables recalculation of
2086   bounding boxes, as requested by Werner Lemberg.
2087-  Renamed tt2xml.pt to ttDump.py and xml2tt.py to ttCompile.py
2088-  Use ".ttx" as file extension instead of ".xml".
2089-  TTX is now the name of the XML-based *format* for TT fonts, and not
2090   just an application.
2091
20921.0a5
2093-----
2094
2095Never released
2096
2097-  More tables supported: hdmx, vhea, vmtx
2098
20991.0a3 & 1.0a4
2100-------------
2101
2102Never released
2103
2104-  fixed most portability issues
2105-  retracted the "Euro_or_currency" change from 1.0a2: it was
2106   nonsense!
2107
21081.0a2 (released 1999-05-02)
2109---------------------------
2110
2111-  binary release for MacOS
2112-  genenates full FOND resources: including width table, PS font name
2113   info and kern table if applicable.
2114-  added cmap format 4 support. Extra: dumps Unicode char names as XML
2115   comments!
2116-  added cmap format 6 support
2117-  now accepts true type files starting with "true" (instead of just
2118   0x00010000 and "OTTO")
2119-  'glyf' table support is now complete: I added support for composite
2120   scale, xy-scale and two-by-two for the 'glyf' table. For now,
2121   component offset scale behaviour defaults to Apple-style. This only
2122   affects the (re)calculation of the glyph bounding box.
2123-  changed "Euro" to "Euro_or_currency" in the Standard Apple Glyph
2124   order list, since we cannot tell from the 'post' table which is
2125   meant. I should probably doublecheck with a Unicode encoding if
2126   available. (This does not affect the output!)
2127
2128Fixed bugs: - 'hhea' table is now recalculated correctly - fixed wrong
2129assumption about sfnt resource names
2130
21311.0a1 (released 1999-04-27)
2132---------------------------
2133
2134-  initial binary release for MacOS
