Mycroft-core v21.2.1 is an iterative release with a whole smattering of goodies.

Most noticeably mycroft-core is becoming compliant with the XDG Base Directory specification. This moves some files from their traditional directories, to those defined by the XDG spec:

• settings to $XDG_CONFIG_DIR/mycroft, which most of the time is ~/.config/mycroft
• data to $XDG_DATA_DIRS/mycroft, which most of the time is ~/.local/share/mycroft
• cache to $XDG_CACHE_HOME/mycroft, which most of the time is ~/.cache/mycroft

Mycroft Skills currently remain at /opt/mycroft/skills/

A series of improvements have also been made to the Voight Kampff test suite to make them more reliable and robust. The better our tests, the quicker we can push other updates.
