24 - [QTBUG-52222] The commercial preview license in the git checkout has
25   been replaced by the Qt License Agreement 4.0 text. This makes it
26   explicit that commercial customers of The Qt Company can use the git
27   version under commercial terms. However, support is (still) only
28   provided for builds from released branches of Qt.

37 - QFile:
38   * [QTBUG-69417] Fixed a regression in QFile::copy() that caused the
39     original file not to be copied entirely if it was modified outside of
40     this QFile object between the last time we checked its size and the
41     copy() call. Note this is not a prevention against race conditions.
42   * [QTBUG-69148] Fixed a regression that caused QFile::map() to succeed
43     or produce incorrect results when trying to map a file at an offset
44     beyond 4 GB on 32-bit Android systems and on some special Linux
45     configurations.
46
47 - QObject:
48   * [QTBUG-69744] Fixed a bug in setProperty() that caused a property
49     change not to take effect if the old value compared equal using
50     QVariant's equality operator, but the values were not strictly equal.
51
52 - QPluginLoader:
53   * Fixed an issue that could cause a crash when certain damaged or

58     rowCount will insert at the bottom of the source model rather than
59     at the row QSortFilterProxyModel::rowCount of the source model.
60
61 - QStorageInfo:
62   * [QTBUG-60215] Fixed a bug that caused the last entry in the mtab file
63     to be ignored on Android.
64   * Fixed a bug on Android that could cause QStorageInfo to skip some
65     filesystems (if the mount table is a virtual file and contains any
66     short lines) or crash (if the mount table contains any 3-field lines).
67
68 - QString:
69   * [QTBUG-63620] Formatting of doubles with single-digit exponent, by
70     number() or args(), now includes a leading zero in that exponent,
71     consistently with sprintf(), as it did up to 5.6.
72
73 - QSysInfo:
74   * Fixed QSysInfo::productType() to properly detect some Linux
75     distributions that ship with a minimal /etc.
76
77 - QTemporaryFile:
78   * [QTBUG-69436] Worked around a bug in the GNU C Library versions 2.21
79     and earlier (used on Linux) that caused temporary files to be created
80     with permissions 000.
81
82 - QUrl:
83   * Fixed a bug that caused URLs whose hostnames contained unassigned or
84     prohibited Unicode codepoints to report isValid() == true, despite
85     clearing the hostname.

98     QTextOption::ShowLineAndParagraphSeparators.
99   * [QTBUG-70096] Fixed a possible crash when combining QStaticText,
