I have default mg 0.8.1 setup and trying to run ./lazycelery doesn't work for me with error:

("\nThe 'celeryd' command is deprecated, please use 'celery worker' instead:\n\n$ celery worker -B\n\n",)

Starting from version 3.2 Celery will refuse to accept pickle by default.

The pickle serializer is a security concern as it may give attackers
the ability to execute any command.  It's important to secure
your broker from unauthorized access when using pickle, so we think
that enabling pickle should require a deliberate action and not be
the default choice.

If you depend on pickle then you should set a setting to disable this
warning and to be sure that everything will continue working
when you upgrade to Celery 3.2::

    CELERY_ACCEPT_CONTENT = ['pickle', 'json', 'msgpack', 'yaml']

You must only enable the serializers that you will actually use.

Right now I am debugging another issue. Chris, could you please take a look if the bug is still in 0.9.0?

A change was made to test_submission.py a while back which did the nice work of adding audio / video upload support. Unfortunately it also switched the codebase so that without the audio/video media type dependencies installed, tests would be failed, when really they should be skipped.

Currently plugins still use sqlalchemy-migrate. In order for our move to Alembic to be complete, and to remove sqlalchemy-migrate support, we need to figure out how to do migrations for plugins with Alembic.

I've been told that ​branching from multiple bases is the right route to go, but someone needs to research it further.
