I rephrased it to the following:
- Amarok now depends on MariaDB embedded, since MySQL embedded was
discontinued. If you still have MySQL embedded, this will continue to work,
as does a full MySQL Server, of course. Unfortunately we need to be
prepared for MariaDB discontinuing the embedded version as well, and we are
considering a port to a new DB backend;
- the script engine has been ported to Qt5's QJSEngine. Sadly the lack of
features from Qt4's QScriptEngine makes the port limited, so there
currently are not many scripts that are compatible. It's likely that a
whole new scripting engine (using QML) will replace the current
implementation.
I will publish this later today.
Regards, Myriam
