OpenSSL
Qt 5.14.0 requires OpenSSL 1.1.1 version on Linux and Windows. Qt online installer provides as convenience both OpenSSL source code and pre-built binaries of the OpenSSL libraries used by Qt Network. However, the installer doesn't set up OpenSSL environment. User needs to define the library path and possible environment variables. OpenSSL libraries are not automatically deployed with applications that are built with Qt. If provided OpenSSL binaries are not suitable for your use case source code installation includes instructions on how to configure and build your own OpenSSL libraries.
Import and export restrictions apply for some types of software, and for some parts of the world. Developers wishing to use SSL communication in their deployed applications should either ensure that their users have the appropriate libraries installed, or they should consult a suitably qualified legal professional to ensure that applications using the code from the OpenSSL project are correctly certified for import and export in relevant regions of the world.

All platforms
QTBUG-80496: If the newly-supported CSS border-width: attribute is defined with less than 4 values for HTML table cells, an index-out-of-range error causes a crash.
QTBUG-80635: SQLite - if a sub-select uses both DISTINCT and window functions, and also has certain ORDER BY usage then it will cause a crash. A patch for this is here: https://codereview.qt-project.org/c/qt/qtbase/+/284320
Windows
- The default for MinGW switched from -debug-and-release to -debug
- MinGW binary packages are created with -release -force-debug-info -separate-debug-info, but the binaries miss the debug packages
- windeployqt does not work for MinGW QTBUG-80763 Will be fixed in 5.14.1

Android
- Qt 5.14.0: The devicePixelRatio scale factor will be rounded to an integer when setting the Qt::EnableHighDpiScaling attribute, unlike previous behavior on Android where the devicePixelRatio was not rounded. As a workaround, call QGuiApplication::setHighDpiScaleFactorRoundingPolicy(Qt::HighDpiScaleFactorRoundingPolicy::PassThrough) at application to disable rounding. Qt 5.14.1 will make PassThrough the default on Android and restore the previous behavior.
- With Qt 5.14.0, unfortunately, release packages of Qt Quick applications will be missing integral files by default, and thus they will crash on startup. You can work around this by disabling the Qt Quick Compiler in the build settings of the project (Projects -> Build Settings -> qmake -> Enable Qt Quick Compiler). See QTBUG-80713 for more details.
