v1.2.0

Upgrade notes

This release contains a database change which might take a while. In order to support quotas, this
release tracks how much a user has uploaded, which might take a while to initially calculate. If you have
a large database (more than about 100k uploaded files), run the following steps before upgrading:

1. The PostgreSQL script described here.
   This can be run while the server is running.
2. If you have no intention of using stats or quotas, you're done (the stats table will be inaccurate). If
   you do plan on using either, run INSERT INTO user_stats SELECT user_id, SUM(size_bytes) FROM media GROUP BY user_id;
   which may take a while.
3. Change the owner of the table and function to your media repo's postgresql user. For example, if your postgres
   user is media, then run:

   ALTER TABLE user_stats OWNER TO media;
   ALTER FUNCTION track_update_user_media() OWNER TO media;
