Offtopic: Qt licensing changes

[Pavel Sanda]

Just FYI ( https://www.qt.io/blog/qt-offering-changes-2020 ):

...
Long-term-supported (LTS) releases will become available to commercial licensees only
...
Starting with Qt 5.15, long term support (LTS) will only be available to
commercial customers. This means open-source users will receive patch-level
releases of 5.15 until the next minor release will become available. .. We are
making this change to encourage open-source users to quickly adopt new
versions. This helps maximize the feedback we can get form the community and to
emphasize the commercial support available to those with longer product life
cycles that rely on a specific Qt version.
