So MySQL 5.1 is declared GA, contains enough bugs to make Monty rail against it publically, doesn't (as far as I've been able to gather) have a stable cross-release pluggable storage engine ABI (despite that being a major release feature -- meaning you have to have new plugin releases for each MySQL server release before upgrading anything), and continues the madness of less frequent community releases and less stable enterprise releases against the wishes of every sensible enterprise customer and (I would guess) every community member.

I know enough about running MySQL to know that Monty's comments don't necessarily reflect much on the practicalities of someone trying to run something using MySQL rather than developing it, but the rest of the noise about this release definitely makes me want to seriously reconsider a policy of using MySQL Enterprise version and look at a real community-released version instead for production use.. There's just a "small" question of figuring out which community..
