Monotone has been updated on Breezy to version 0.44.

If you have existing monotone databases, you will  need to migrate them to the new format. Depending on the size of your database this may take a few seconds to some minutes. To migrate your database issues the following command:

mtn -d YOURDATABSE.DB db migrate

Please remember to make a backup of your existing monotone database prior to migrating it.
