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. **************************************************************************** * 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. **************************************************************************** * Third-Party Code * **************************************************************************** - [QTBUG-69274] SQLite was updated to version 3.24.0. - [QTBUG-69271] PCRE2 was updated to version 10.31. **************************************************************************** * plugins * **************************************************************************** - ibus: * Qt programs in Flatpak environment can now trigger IBus input method.
