release notes for details http://www.slimdevices.com/Changelog6.html.
Fix a longstanding bug that caused mDNS support to not actually work.
Take advantage of improvements in rc.subr to reduce the amount of code
in the shutdown path including removing the pgrep dependancy.
The biggest change is that the database is now MySQL instead of SQLite.
Slimserver starts it's own MySQL instance so you don't need to deal with
MySQL configuration, but both the client and server are now
dependencies. For more info see the change log at:

Most of the binary perl modules are now port dependencies. YAML-Syck is
not yet because it didn't work. I suspect a version issues (the ports
version is newer).
