MediaGoblin 0.12.0 released

[Ben Sturmfels]

Happy Software Freedom Day! Today we're pleased to announce the release
of MediaGoblin 0.12.0.

MediaGoblin is a free software media publishing platform that anyone can
run. You can think of it as a self-hosted alternative to Flickr, YouTube
or SoundCloud

This release resolves two significant issues in the Celery backend media
processing. The first was causing processed media to be marked as failed and the
second was inhibiting useful error messages. We've also resolved installation
issues caused by deprecated upstream code in the Werkzeug and jsonschema
libraries.

We've added provisional `gmg serve` and `gmg celery` commands to simplify
deployment. These commands may change in the future and are not yet recommended
in the deployment documentation. If your deployment is already running smoothly,
there's no reason to switch at this stage.

See the release notes and upgrade instructions:
https://docs.mediagoblin.org/en/v0.12.0/siteadmin/relnotes.html

If you have any problems, please drop in to the #mediagoblin IRC chat, report an
