- Check that your system meets Qt's requirements
- All open issues can be found from Jira
- RTA findings here
- Supported development platforms are listed here
All platforms
- 6.7.2, 6.7.3 Formatting a datetime, with a format that includes its time-zone or offset may crash, for local time or the system time-zone, if determining the system time-zone fails (QTBUG-129696).
- 6.7.3 An erroneous assert in QDateTimeParser may trigger on valid dates when parsed using e.g. QDate::fromString.
- This only applies to debug builds of Qt or builds of Qt is configured with asserts enabled for release builds.
- QDate::fromString is used internally in various places in Qt, including Network, so the assert may be triggered indirectly.
- 6.7.3 If QLocale::uiLanguages() shows multiple languages, QTranslator::load() might load lower-priority ones (QTBUG-129434).
- 6.7.3 Qt Designer does not write out layout alignment properties correctly (QTBUG-129503)
- 6.7.3 QString::replace(pos, len, replacement) fails to check that replacement doesn't alias *this before resizing, causing a read of possibly-deleted data (fix: https://codereview.qt-project.org/c/qt/qtbase/+/627375). Work-around: make sure that the replacement is not aliasing *this.
- 6.7.0-3 QAbstactItemView fails to disconnect from the old QAbstractItemDelegate (fix: https://codereview.qt-project.org/c/qt/qtbase/+/636220). Work-around: ensure the old item delegate is deleted after the new one is set.
Linux
- Commercial only Debian repositories
- missing debian packages for QtWebengine, QtWebview and QtGrpc
- missing qt6.6.0-full-dbg meta package.
- Building QtApplicationManager projects using the arm64 config from the Installer might fail because of a missing dependency (QTBUG-123796)
macOS
- Due to changes in notarization from XCode 13 onwards, macOS debug information files are delivered as part of the online installer only and installed automatically.
Windows
WindowsVistaStyle: Embedding QComboBox into QScrollArea results in black QComboBox-Popup.
WebEngine: Using OpenGL as RHI backend will unconditionally crash WebEngine in 6.7.0. The issue is resolved in the 6.7.1 release.
Android
iOS
- Deploying and running applications on iOS 17 devices via Qt Creator is currently unsupported, due to changes in the underlying Apple libraries used to communicate with the device. As a workaround, open the Xcode project generated by Qt Creator and run and debug the application via Xcode.
WebAssembly
Embedded Linux
- Widget applications using QMenu crash when menus are used with EGLFS platform plugin, see QTBUG-123962
