Today we have released a new version, 0.11.1. As with all point releases it is a bug fix only release. With over 81 tickets closed, this is definetly a significant release for Doctrine towards 1.0. We recommend that you upgrade.
We have also created the 1.0 branch and will begin actively working on it. We have hit the final straight away towards 1.0! This was originally slated to be the 0.12 branch but we feel it is ready and we will spend the next 2 months furiously working on tickets before we release it on September 1st. We will have some short intermediate BETA and RC releases before then but these will primarily be bug fix releases only. Make some hype please, thanks. ;)
