Revision control
++ Qt 5.13.1 is a bug-fix release. It maintains both forward and backward
++ compatibility (source and binary) with Qt 5.13.0.
++
++ For more details, refer to the online documentation included in this
++ distribution. The documentation is also available online:
++
++
++ The Qt version 5.13 series is binary compatible with the 5.12.x series.
++ Applications compiled for 5.12 will continue to run with 5.13.

++ ****************************************************************************
++ * Important Behavior Changes *
++ ****************************************************************************
++
++ - [QTBUG-76521] RCC's default compression algorithm was changed back to
++ Zlib, as it was in all previous releases until 5.13.0. The default will
++ remain Zlib for all Qt 5.x releases but will change in Qt 6.0. To
++ activate Zstd compression for your resources, either pass the
++ --compress-algo=zstd option to the rcc tool or add the XML attribute
++ compression-algorithm="zstd" to the <file> tags in the .qrc file.
++
++ ****************************************************************************
++ * Android *
++ ****************************************************************************
++
++ - [QTBUG-76293] Fix NDK r20 linking.
++
++ ****************************************************************************
++ * QtCore *
++ ****************************************************************************
++
++ - Global:
++ * [QTBUG-72073] Added the QT_NO_FLOAT16_OPERATORS macro in order to work
++ around a Microsoft <= VS2017 compiler bug that is exposed when using
++ std::bitset along with any Qt header that includes <qfloat16.h>.
++
++ - QCborStreamReader:
++ * Fixed a bug that caused the QIODevice that the data was being read
++ from not to show the entire CBOR message as consumed. This allows the
++ user to consume data that may follow the CBOR payload.
++
++ - QDeadlineTimer:
++ * [QTBUG-69750] Fixed integer overflows leading to immediate timeouts.
++
++ - QStorageInfo:
++ * Fixed a bug that caused QStorageInfo to be unable to report all
++ filesystems if the options to mounted filesystems were too long (over
++ 900 characters, roughly), such as those found in Docker overlay
++ mounts.
++
++ - QTextBoundaryFinder:
++ * Sentence breaking now no longer breaks between uppercase letters and
++ comma. This is a deviation from the Unicode specification, but
++ produces less surprising behavior.
++
++ - QTimeZone:
++ * The IANA timezone database backend now properly follows symlinks even
++ when they point to variable locations like /run or /var (useful when
++ /etc is mounted read-only).
++
++ - QVector:
++ * Fixed a regression that caused fill() not to detach, corrupting shared
++ copies.
++
++ ****************************************************************************
++ * QtNetwork *
++ ****************************************************************************
++
++ - Windows:
++ * Correctly emit errors when trying to reach unreachable hosts or
++ services
++
++ - QNetworkAccessManager:
++ * Fixed QNetworkAccessManager::sendCustomRequest for Qt For WebAssembly.
++
++ ****************************************************************************
++ * QtGui *
++ ****************************************************************************
++
++ - [QTBUG-73231] QWindow::mapToGlobal()/mapFromGlobal() now handle windows
++ spanning screens correctly.
++
++ - QImage:
++ * Improve loading time when loading png files that have the same size as
++ the target.
++
++ - QPixmapCache:
++ * [QTBUG-76694][QTBUG-72523] Ignore unsafe access from non-main threads
++
++ - Text:
++ * [QTBUG-76219] Fixed a bug which could cause the font cache to grow
++ larger than it was supposed to.
++ * [QTBUG-55096][QTBUG-74761] Fixed bug where regular text rendered with
++ a color font would always display in black.
++
++ ****************************************************************************
++ * QtWidgets *
++ ****************************************************************************
++
++ - QSystemTrayIcon:
++ * On macOS, show the icon passed into showMessage in the notification
++ popup
++
++ - QDateTimeEdit:
++ * Use the information provided by the locale to determine the AM/PM
++ strings, unless they are already translated.
++
++ - QGraphicsView:
++ * Ignore disabled items when setting the mouse cursor.
++
++ - QMenu:
++ * Shortcuts are again shown by default in context menus, except on
++ macOS. They can be forced off by setting
++ AA_DontShowShortcutsInContextMenus to true.
++
++ - QSplashScreen:
++ * On macOS, lower the splash screen when a modal dialog is shown to make
++ sure the user sees the dialog.
++
++ ****************************************************************************
++ * Third-Party Code *
++ ****************************************************************************
++
++ - Updated bundled SQLite to version 3.28.0
++ - Updated QLocale's data to CLDR v35.1
++
++ ****************************************************************************
++ * qmake *
++ ****************************************************************************
++
++ - [QTBUG-75653] The CONFIG value c++latest was added to select the latest
++ C++ standard the currently used toolchain supports.
