Adding Pierre's Opinion


MySQL 5.5 is now in [extra]. This is a major version upgrade from the
5.1 editions previously in the repositories. Archive, Blackhole, and
Federated engine support are no longer included in this package, since
they are not heavily used.

After upgrading the MySQL package and restarting the database, you
will need to run `mysql_upgrade` to ensure your tables, views and
stored procedures are up to date and compatible with MySQL 5.5.

Is always good to do a backup of your databases, before doing the
update, you will also need to adjust my.cnf options in order to make
it compatible with 5.5 release, <a
info available here</a>

End of Draft

I've delayed the update until the draft is completely approved, but I
hope to do it today.
