What's the latest on MySQL Proxy?
From an email on the MySQL lists sent earlier this month, Shawn Green (a MySQL Principal Technical Support Engineer) reports:


  Thanks to the corporate changes of the last few years, the sole developer has been too busy doing his primary job to really put any more time into the project and no person or group from the community has stepped forward to help push the project to a final deliverable state.


So I suppose the latest state of development is it's on hold.
