+
+ - Fixed the icons for the "file save" action that were inaccurate
+   representations of a 3.5-inch floppy disk (the cut edge was on the wrong
+   side). Now all floppy representations are physically accurate.

+
+ - QCommandLineParser:
+   * [QTBUG-70174] Fixed a bug that caused the help output to show two
+     options or more in the same line if the options didn't have a
+     description.
+
+ - QDateTime:
+   * [QTBUG-70823] Fixed parsing of date/time strings when the day is the
+     start of daylight savings and that starts at midnight on the
+     timezone.
+
+ - QPluginLoader:
+   * [QTBUG-70560] Fixed a bug in parsing certain plugins, which might
+     conclude a valid plugin wasn't valid.
+
+ - QPointer:
+   * [QTBUG-71412] Fixed a race condition that would cause an assertion
+     failure when two threads created a QPointer for the same QObject.
+
+ - QUrl:
+   * Fixed a bug that caused QUrl::matches to incorrectly compare two URLs
+     with different hostnames or different usernames as equal, if certain
+     QUrl::RemoveXxx options were passed.
+   * [QTBUG-70386][QTBUG-70852] Updated the public DNS suffix list.

+****************************************************************************
+
+ - Fixed a number of incompatibilities with Linux C libraries due to use of
+   new kernel system calls statx(2) and renameat2(2). In order to enable
+   them now in Qt, they need to be provided in the C library's own
+   headers. Currently, glibc 2.28 contains them.
