We are happy to announce the immediate availability Doctrine ORM 2.5.0-alpha2.

This is a pre-release meant to allow users and contributors to try out the new upcoming features of the ORM.

We encourage all of our users to help us by trying out this alpha release. Please report any possible problems or incompatibilities that may have been introduced during development.

This pre-release is not yet at feature-freeze, therefore we urge contributors to contact us if there is any change that requires our attention before we reach the beta (feature-freeze) release stage.
