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. feedback: 0004_index_together hybridcloud: 0016_add_control_cacheversion nodestore: 0002_nodestore_no_dictfield remote_subscriptions: 0003_drop_remote_subscription replays: 0004_index_together sentry: 0787_make_dashboard_perms_col_nullable social_auth: 0002_default_auto_field uptime: 0017_unique_on_timeout workflow_engine: 0011_action_updates
