Django migrations lock file. This helps us avoid migration conflicts on master. If you have a conflict in this file, it means that someone has committed a migration ahead of you. To resolve this, rebase against latest master and regenerate your migration. This file will then be regenerated, and you should be able to merge without conflicts. nodestore: 0002_nodestore_no_dictfield replays: 0003_add_size_to_recording_segment sentry: 0530_new_notification_tables social_auth: 0002_default_auto_field
