All platforms

• Calling mapFromItem() or mapToItem() between items where one of the items are not yet in a scene may crash (see QTBUG-129500). As a workaround, condition the call on the items both having a Window.window.
• Using the 'Repeated' suffix in the protobuf message name causes compilation issue (see QTBUG-129652).
• Qt Designer does not write out layout alignment properties correctly (QTBUG-129503)
• 6.8.0: 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, fixed in 6.8.1).
• 6.8.0: The newly-added support for recognizing time-zones by various aliases may, in some cases, fail to recognise some aliases (fixed in 6.8.1).

Linux

• When using GNOME Wayland 46.0, Qt Designer's main window may not show under certain circumstances. The issue should be resolved in GNOME Wayland 46.2 (see QTBUG-127920 ).
• For Linux arm64/aarch64, if system glibc < 2.38, can't use official binary from Qt Installer. Workaround is build from source. (see QTBUG-129421 ).

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

• Windows on ARM: Debuggers And Tools ARM64 redistributable package is not available from Qt online installer / Qt Creator. Debuggers And Tools can be installed e.g. with MSVC 2022 ARM64 installation (see QTBUG-129157).
• 6.8.0: Windows with ICU: fails to build, see QTBUG-129896 (fixed in 6.8.1).
