Release note

Qt 6.5.1 release is a patch release made on the top of Qt 6.5.0.
As a patch release, Qt 6.5.1 does not add any new functionality but provides
bug fixes and other improvements and maintains both forward and backward
compatibility (source and binary) with Qt 6.5.0.

For detailed information about Qt 6.5, refer to the online documentation
included in this distribution. The documentation is also available online:

https://doc.qt.io/qt-6/index.html

The Qt version 6.5 series is binary compatible with the 6.4.x series.
Applications compiled for 6.4 will continue to run with 6.5.

Some of the changes listed in this file include issue tracking numbers
corresponding to tasks in the Qt Bug Tracker:

https://bugreports.qt.io/

Each of these identifiers can be entered in the bug tracker to obtain
more information about a particular change.

To make it easier to port to Qt 6, we have created a porting guide to
summarize those changes and provide guidance to handle them. In the
guide, you can find links to articles about changes that may affect your
application and help you transition from Qt 5.15 to Qt 6:

Important Changes

qtbase

bc070591c2 QMessageAuthenticationCode: remove lazy initialization of
messageHash
No longer delays processing of the key to the first setData() or
result() call. While passing a default-constructed key to the
constructor and then calling setKey() continues to work, for optimal
performance, we suggest to pass the actual key as a constructor argument
and call setKey() only to change the key.
1ac4375135 QErrorMessage: Reset 'again' check box between each error
message
QErrorMessage will now reset the check box for showing a message again
for each new message shown, as each individual message has its own
suppression state.
7508dad289 QFSFileEngine: fix overflow bug when using lseek64
Fixed a bug where opening a file in append mode may fail if the file
size was bigger than INT_MAX.
fa34315a5a CMake: Add NO_COMPILER_RUNTIME to deploy script macros
Added the option NO_COMPILER_RUNTIME to qt_generate_deploy_app_script.
b006c2437a SQLite: Update SQLite to v3.41.1
Updated SQLite to v3.41.1
b105e128db QProcess: reimplement systemEnvironment() using
QProcessEnvironment
Fixed a bug that would cause systemEnvironment() to produce corrupted
entries (mojibake) on Windows if the environment contains characters
outside of the ANSI character set.
d3bc8c79bb QTimer: fix new-style slot invocation for receiver in
another thread
Fixed a bug that caused slots connected to single-slot timers using the
new-style connection mechanism to be delivered in the wrong thread.
b9d25848f0 Update license specification for PCRE2
Clarifying license of PCRE2 to be BSD-3-Clause with advertisement
exception for binary-like packages.
766d5daf3b SQLite: Update SQLite to v3.41.2
Updated SQLite to v3.41.2
72487c52fb QMultiHash: fix missing update to m_size
to not be counted, resulting in a hash map with an incorrect element
count and which could cause an assertion failure depending on how the
hash was later mutated.
b87883951e QPluginLoader: don't instantiante multiple, identical
instances
staticInstances() will not call duplicated registrations of the same
instantiation function, which can only happen as a result of duplicated
Q_IMPORT_PLUGIN for the same plugin name.
dd8b648e69 Fix accessibility on XCB when running as root
On XCB applications running as root are now accessible.
92b56cab18 CMake: Store unsanitized plugin type names in module .json
files
The module information JSON files now contain the unsanitized plugin
types of a module, e.g. wayland-decoration-client instead of
wayland_decoration_client. Consumers of the module information file must
sanitize plugin types themselves if necessary.
e53911842a win: Fix default fallback font for some languages
Fixed an issue querying a default font for certain languages not
supported by the primary system font.
709e603664 Windeployqt: Add a check for LLVM-MinGW runtimes
Windeployqt now supports LLVM-MingGW runtimes.
55aee86975 QDnsLookup/Unix: make sure we don't overflow the buffer
Fixed a bug that could cause a buffer overflow in Unix systems while
parsing corrupt, malicious, or truncated replies.

qtsvg

2570796 Don't rasterize gigantic shapes
Unreasonably large shapes are now ignored in SVG files to avoid
stalling the application. The check can be disabled by setting
QT_SVG_DISABLE_SIZE_LIMIT=1 in the environment.
d40f1c6 QSvgFont: Initialize used member, remove unused
Fixed undefined behavior from using uninitialized variable.

qtdeclarative

50cff47d14 CMake: Add NO_COMPILER_RUNTIME to
qt_generate_deploy_qml_app_script
Added the option NO_COMPILER_RUNTIME to
qt_generate_deploy_qml_app_script.
8fae0aa4ae QQuickItemView: Skip instantiating delegates if size is 0
If a ListView has size zero, it won't instantiate any delegates until
its size becomes non-zero.
466e17a9ae Fix StackLayout to keep the current visible item after
insert/removal
StackLayout will now update currentIndex if an Item is inserted or
removed at an index less than or equal to the current index.

qttools

54a77b524 lupdate: Handle C++ string literals
lupdate now supports prefixed string literals like u"foo".
