Release v13 is mainly a bug fix release, in particular,
it should fix a major database corruption bug which caused the
database to be cleared in some cases.

v12 brings:

* better support of removable media: non-existent directories are no longer immediately removed from the database
* respect people's home directories: try to put stuff in ~/.local/share/autojump when possible
* better installers
* ...and of course, the usual bug fixes!

software polishing

Lots of new features since the first (arch) release:

* zsh support
* performance improvements
* jumpapplet
* many bugfixes
