ActiveRecord Versioning plugin/gem compatible with rails3?

I googled for the the plugin/gem to do the ActiveRec开发者_运维知识库ord versioning for Rails3.

But all I've got is not compatible for Rails3. I even searched in RailsPlugins.org too, but no luck.

Do you know any that is Rails3 ready?

The acts_as_versioned gem seems to not officially support rails3 yet, but this guy has forked the project and created a rails3 branch. Take a look at it.
