Mikrotik Changelog V4.4

It can be found here.

Looks like a small round of bug fixes.

Notable are
*) removed support for xen;
Interesting drop.

*) routing – added support for BFD protocol;
Looks like they are starting to roll it out. Still nothing in the wiki on it, though.

*) fixed problem – MetaROUTER sometimes froze on RB4xx;
All you 450/metarouter users need to upgrade.
