Important Changes

qtbase

  • bd27707c20 Always update QPalette resolve mask, regardless of QBrush
    change
    Always update resolve mask in QPalette::setBrush, even if the value of
    brush has not changed.

  • 1bdf2799eb Support test-case selection based on global data tag
    When specifying what tests to run on a QtTest command-line, it is now
    possible to include a global data tag in the same way as a function-
    specific data tag or in combination with it. Thus if the test reports
    itself as tst_Class::function(global:local), command-line option
    function:global:local will select that specific test and function:global
    will run all data-rows for the function on the given global data tag.

  • bdb4b80e9d SQLite: Update SQLite to v3.39.2
    Updated SQLite to v3.39.2

    libjpeg-turbo was updated to version 2.1.4

  • 118558c5b2 QHttp2Configuration: in QNAM, use old, higher values in
    flow control
    Stream receive window that HTTP/2 protocol in QNAM is using increased
    to 214748364 octets (from the previous 64K) not to throttle download
    speed. Clients, working with servers, not accepting such parameters,
    must set HTTP/2 configuration on their requests accordingly.

  • 978087f351 Fix crash when setting override cursor on multiple clients
    Fixed a crash when setting an override cursor on multiple clients.
