Subject [ANN] Cayenne 3.1M3 release
Date Mon, 26 Sep 2011 07:19:26 GMT
We are glad to announce 3.1M3 release of Cayenne. This is an important milestone on our way
to Beta. In fact there is a good chance that the next release will be announced as Beta. Upgrade
to M3 is strongly recommended to all 3.1 users, as it contains some critical bug fixes. The
highlights of the M3:

* Core API improvements - cleaner vararg APIs in ObjectContext and Cayenne classes, ObjectContext.localObject(Object),
* Switching more of the internals to DI (query cache providers, loggers, various strategies
controlling ObjectContext behavior, etc.).  We'll keep working on this, so M4 will have more
of it, and in fact there are a number of existing patches waiting for review (e.g. DI-based
* New QueryCache implementation based on EHCache (not thoroughly tested yet, so user feedback
will be very helpful).
* Refactoring of "cayenne-lifecycle" based on experience using it in the real apps.
* Fixing a number of critical bugs.
