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 sentry: 0351_project_has_checkins_monitors social_auth: 0001_initial
