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   been replaced by the Qt License Agreement 4.0 text.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

QtCore
------

 - QFile:
   * [QTBUG-69417] Fixed a regression in QFile::copy() that caused the
     original file not to be copied entirely if it was modified outside of
     this QFile object between the last time we checked its size and the
     copy() call. Note this is not a prevention against race conditions.
   * [QTBUG-69148] Fixed a regression that caused QFile::map() to succeed
     or produce incorrect results when trying to map a file at an offset
     beyond 4 GB on 32-bit Android systems and on some special Linux
     configurations.

 - QObject:
   * [QTBUG-69744] Fixed a bug in setProperty() that caused a property
     change not to take effect if the old value compared equal using
     QVariant's equality operator, but the values were not strictly equal.

 - QPluginLoader:
   * Fixed an issue that could cause a crash when certain damaged or
     corrupt plugin files were scanned.

 - QSortFilterProxyModel:
   * [QTBUG-58499][QTBUG-69158] insertRows(row,count,parent) with row ==
     rowCount will insert at the bottom of the source model rather than
     at the row QSortFilterProxyModel::rowCount of the source model.

 - QStorageInfo:
   * [QTBUG-60215] Fixed a bug that caused the last entry in the mtab file
     to be ignored on Android.
   * Fixed a bug on Android that could cause QStorageInfo to skip some
     filesystems (if the mount table is a virtual file and contains any
     short lines) or crash (if the mount table contains any 3-field lines).

 - QString:
   * [QTBUG-63620] Formatting of doubles with single-digit exponent, by
     number() or args(), now includes a leading zero in that exponent,
     consistently with sprintf(), as it did up to 5.6.

 - QSysInfo:
   * Fixed QSysInfo::productType() to properly detect some Linux
     distributions that ship with a minimal /etc.

 - QTemporaryFile:
   * [QTBUG-69436] Worked around a bug in the GNU C Library versions 2.21
     and earlier (used on Linux) that caused temporary files to be created
     with permissions 000.

 - QUrl:
   * Fixed a bug that caused URLs whose hostnames contained unassigned or
     prohibited Unicode codepoints to report isValid() == true, despite
     clearing the hostname.

QtGui
-----

 - QMatrix:
   * The qHash() implementation for QMatrix has been changed.

 - QTransform:
   * The qHash() implementation for QTransform has been changed.

 - Text:
   * [QTBUG-69661] Fixed potential crash when using
     QTextOption::ShowLineAndParagraphSeparators.
   * [QTBUG-70096] Fixed a possible crash when combining QStaticText,
     QOpenGLWidget and Qt Quick in the same application.

 - Qt programs in Flatpak environment can now trigger IBus input method.

QtWidgets
---------

 - QMessageBox:
   * [QTBUG-69526] A message box with two buttons, one of which is the "Show
     Details..." button, can now be closed by clicking the X button on the
     window's title bar.

 - QFileDialog:
   * QFileDialog::selectedMimeTypeFilter() now returns the actually
     selected name filter.
