In addition, the code had 453 dropped the name mapping to Windows font names. 454 - PostScript output had an extraneous '%' character on the first line, 455 which would cause printing to fail. 456 - Text handling, during both sizing and layout, incorrectly handled 457 empty lines such as label="\nabc". 458 - HTML-like tables had been changed to use too much vertical space, 459 to possibly use the wrong font in calculating the height of a line, 460 and to use the wrong offset when moving the baseline from one line to 461 the next. 462November 27, 2006 463 - release 2.10 464 - dot - New pango+cairo renderer plugin (was in separate graphviz-cairo tree). 465 -- -Tpng now uses cairo (-Tpng:gd for old gd based renderer) 466 -- -Tpdf now available 467 -- -Tps:cairo now available (-Tps is a direct ps renderer not based on cairo) 468 -- -Tsvg:cairo now available (-Tsvg is a direct svg renderer not based on cairo) 469 -- -Txlib now available -- "dot -Tx11 foo.dot" watches foo.dot with inotify and updates 470 -- -Tgtk now available -- eventually to provide a graph editing capability - not fully working 471 -- -Tswf "Flash" now available using the ming library. Currently has incomplete font support and not yet in Fedora rpms because ming not yet available as rpm. 472 - remove hard gd dependencies from dot. gd renderers now provided 473 as optional plugin. Deprecated, but required for -Tjpg, -Tgif and -Tvrml. 474 - gvpr - Add kindOf function, plus functions to set and get default values 475 - dot - Implement esep attribute to allow graph to specify room 476 around nodes for spline routing. 477 - neato - add vpsc library and DIGCOLA 478 - neato - add IPSEPCOLA additions from Tim Dwyer 479 - move: -Tps, -Tfig, -Tsvg, -Timap/ismap/cmap/cmapx, -Tdot/xdot, 480 from codegens to a "core" plugin. 481 - dot - new usershape plugin mechanism potentially supporting 482 a wider range of input shape format -> output format combinations. 483 display on changes 484 - Fixes for builds on Mac OS/X 485 - dot - new -O switch to automatically generate output file 486 names based on the input filename and the -T value. 487 e.g. "dot -Tpng -O *.dot" 488 Also works for case of multiple graphs in a single input file. 489 - add support for "Brewer" color nameset 490 - move reusable .so libraries to $PREFIX/lib per frequent request 491 from Debian community. Plugin .so's remain in $PREFIX/lib/graphviz. 492 - Fix bugs 882 884 886 896 902 905 906 911 918 919 933 936 938 940 493 948 955 958 967 979 987 993 1005 1006 1011 1012 1013 1014 1016 494 1018 1025 1030 1034 1035 1039 1040 debian#37300 495 496February 3, 2006 497 - release 2.8 498 - (POTENTIAL INCOMPATIBILITY) The default input scaling, in the 499 absence of a "-s" switch, has been changed from inches to points. 500 The new behavior of "neato" is equivalent to "neato -s72". 501 The old behavior can be restored with "neato -s1". 502 The purpose of this change is to avoid a Frequently-Made-Mistake 503 when using "neato -n" to process a previously generated layout. 504 Previously it was necessary to use "neato -n -s72", but with this 505 change the default matches dot's output and the "-s72" is not required. 506 - Added pseudo layout engines: "dot -Knop" and dot -Knop1" equivalent 507 to "neato -n" 508 - Added pseodo layout engine: "dot -Knop2" equivalent to "neato -n2" 509 - Add support for color namespaces; add Brewer color data 510 -

Add special purpose code to deal with html labels from language 519 bindings. 520 - Various portability fixes for: HPUX, Mac OS/X, Cygwin, Windows. 521 - Fix bugs 784 786 787 788 789 790 791 793 795 796 798 799 522 800 801 804 806 811 812 817 820 821 823 824 825 830 523 837 839 841 842 843 848 850 851 854 855 856 857 858 524 859 861 863 866 867 869 872 874 876 877 525 526August 28, 2005 527 - release 2.6 528 - experimentally moved source code management from CVS to GIT 529 - added iterator functions to script bindings 530 - more C-API tuning 531 - add "-c" switch to dot to explicitly generate plugin "config" file 532 instead of generating it as a side-effect of "dot -V" 533 -

Colors flow along edges from tail to head. 1130 1131 gc : a graph analogue to wc in that it prints to standard 1132 output the number of nodes, edges, connected components or 1133 clusters contained in the input files. 1134 1135 gpr : a graph stream editor inspired by awk. It copies 1136 input graphs to its output, possibly transforming their 1137 structure and attributes, creating new graphs, or 1138 printing arbitrary information. 1139 1140 nop : reads a stream of graphs and prints each in 1141 pretty-printed (canonical) format on stdout. 1142 1143 sccmap : decomposes digraphs into strongly connected components 1144 and an auxiliary map of the relationship between components. 1145 1146 tred : computes the transitive reduction of directed graphs, 1147 and prints the resulting graphs to standard output. This 1148 removes edges implied by transitivity. 1149 1150 unflatten : is a preprocessor to dot that is used to improve 1151 the aspect ratio of graphs having many leaves or disconnected 1152 nodes. The usual layout for such a graph is generally very 1153 wide or tall. unflatten inserts invisible edges or adjusts 1154 the minlen on edges to improve layout compaction. 1155 1156 1157 FIXES 1158 1159 Add FAQ 1160 1161 Change PNG default background color from transparent to white 1162 because of the difficulty some viewers have with transparency. 1163 1164 Add support for [color=transparent] 1165 1166 Fix broken support for specific capitalized fontnames 1167 (Times Helvetica Arial Courier) 1168 1169 Fix broken support for DOTFONTPATH 1170 1171 Some bitmap font scaling fixes - we're still not happy with 1172 bitmap font scaling as some labels still exceed the area 1173 allocated by the layout engines. 1174 1175 Some -Timap fixes for mouse sensitive graphs on web pages 1176 1177 Some cluster layout fixes 1178 1179 Fix for [rankdir=LR] problems when using neato layout engine 1180 1181 Some neato layout fixes 1182 1183 Updates to unix.dot 1184 1185 Various OS and distro fixes 1186 1187 1188December 23, 2000: graphviz-1.7.5 1189 1190 - update to gd-1.8.4 and freetype2 1191 - add support for font paths 1192 1193 1194December 15, 2000: graphviz-1.7.4 1195 -various cluster fixes 1196 -separate support for node fillcolor from pencolor (see dot.1) 1197 -add support for dotted and dashed lines to bitmap renderers (PNG, GIF etc) 1198 -add support for varying linewidth to bitmap renderers 1199 -remove libtcldot dependence on lingdtclft (already statically included) 1200 -various fixes to build processes, GNU and non-GNU 1201 1202 1203graphviz-1.7.3 ..... 1204 1205May 3, 2000: removed webdot into its own CVS module and rpm package 1206 1207April 16, 2000: Use check for "gdImagePng" to make sure that we have 1208 recent version of libgd. <ellson@graphviz.org> 1209 1210April 14, 2000: Add Tcldgl and dge demo <ellson@graphviz.org> 1211 1212April 14, 2000: Add dynagraph libraries <north@research.att.com> 1213 1214April 14, 2000: Flatten directory hierarchy of sources <ellson@graphviz.org> 1215 1216April 14, 2000: Fix X11 library detection for lefty: 1217 src/configure.in, src/lefty/Makefile.in 1218 <ellson@graphviz.org> 1219 1220April 14, 2000: Fix pic support: 1221 src/dotneato/picgen.c, 1222 src/dotneato/emit.c, 1223 webdot/tcl/webdot.tcl 1224 <Bruce Lilly> 1225 1226April 7, 2000: Upgrade webdot installation process: 1227 webdot/Makefile, webdot/README 1228 <ellson@graphviz.org> 1229 1230March 13, 2000: Support for virtual hosts in webdot/webdot.tcl, add 1231 "puts $skt "Host: $server" Michael Tillberg <mt@proteome.com> 1232 1233March 13, 2000: Fix to src/graph/parser.y line 149 1234 "if ((e->head == t->node) && !(Agraph_type & AGDIGRAPH)) {" 1235 Stephen North <north@research.att.com> 1236 1237March 13, 2000: Use AM_PROG_LIBTOOL instead of AC_PROG_LIBTOOL 1238 in configure.in.
