Important Notes
---------------

This release depends on Celery version 2.1.0.
Be sure to read the Celery changelog before you upgrade:
http://celery.github.com/celery/changelog.htmlversion-2-1-0

News
----

* The periodic task schedule can now be stored in the database and edited via
the Django Admin interface.

To use the new database schedule you need to start ``celerybeat`` with the
following argument::

$ python manage.py celerybeat -S djcelery.schedulers.DatabaseScheduler

Note that you need to add your old periodic tasks to the database manually
(using the Django admin interface for example).

* New Celery monitor for the Django Admin interface.

To start monitoring your workers you have to start your workers
in event mode::

$ python manage.py celeryd -E

(you can do this without restarting the server too::

>>> from celery.task.control import broadcast
>>> broadcast("enable_events")

You need to do a syncdb to create the new tables:

python manage.py syncdb

Then you need to start the snapshot camera::

$ python manage.py celerycam -f 2.0

This will take a snapshot of the events every 2 seconds and store it in
the database.

Fixes
-----

* database backend: Now shows warning if polling results with transaction isolation level
repeatable-read on MySQL.

See http://github.com/celery/django-celery/issues/issue/6

* database backend: get result does no longer store the default result to
database.

See http://github.com/celery/django-celery/issues/issue/6

Important notes
---------------

* Due to some applications loading the Django models lazily, it is recommended
that you add the following lines to your ``settings.py``::

import djcelery
djcelery.setup_loader()

This will ensure the Django celery loader is set even though the
model modules haven't been imported yet.

News
----

* ``djcelery.views.registered_tasks``: Added a view to list currently known
tasks.
