It maintains both forward and backward +compatibility (source and binary) with Qt 5.11.0 through 5.11.2. + +For more details, refer to the online documentation included in this +distribution. The documentation is also available online: + +http://doc.qt.io/qt-5/index.html + +The Qt version 5.11 series is binary compatible with the 5.10.x series. +Applications compiled for 5.10 will continue to run with 5.11. + +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. + +**************************************************************************** +* Third-Party Components * +**************************************************************************** + + - libpng was updated to version 1.6.35 + - PCRE2 was updated to version 10.32. + - Added documentation for the SLJIT part of pcre2, which is available + under the BSD-2-Clause license. + +**************************************************************************** +* Documentation * +**************************************************************************** + + - 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. + +**************************************************************************** +* QtCore * +**************************************************************************** + + - 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. + +**************************************************************************** +* QtGui * +**************************************************************************** + + - QPicture: + * [QTBUG-71208] Fix crash reading malformed picture file + +**************************************************************************** +* QtNetwork * +**************************************************************************** + + - SSL: + * [QTBUG-68156] OpenSSL >= 1.0 is now required to build Qt with OpenSSL + support. + +**************************************************************************** +* Linux * +**************************************************************************** + + - 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. + +**************************************************************************** +* macOS * +**************************************************************************** + + - Offline renderers will be disabled when the application is + using Qt WebEngine and running on one of the late 2013 Mac Pro models.
