Celery 2.3 released!
After several delays, 2.3 is finally here!
This release contains automatic connection pool support (not enabled by default), chords (aka taskset callbacks), custom time limits for individual tasks, and more.
Results are now disabled by default, if you depend on the amqp result backend being the default, then you have to configure that manually before upgrading.
Everything is detailed in the Changelog, which you should have read before upgrading.
Users of Django must also upgrade to django-celery 2.3.
Big thanks to all contributors and users!
