(Note that for Windows users we recommend uninstalling the previous version
before installing the new one.)
-Change database backend for config file. There should be no more errors
which cause you to delete the config file.
-Don't import cherrypy if not using the sync server (workaround for mimetype
bug in non-unicode systems) (reported by Steven Lee, Pete Kovalenko).
-Don't give spurious warning about different tags in different sister cards
when creating new clozes when editing a card (reported by Scott Youngman).
-Fixed some issues with tabbing to buttons in a dialog not selecting the right
button (reported by Scott Youngman).
