- To avoid redefining migrate manage command is added new application configuration class which emit post_migration signal. This signal require models module inside application and defined AppConfig Instance as signal sender. Documentation here: https://docs.djangoproject.com/en/1.8/ref/signals/#post-migrate. - Add AppConf subclass to __init__ zerver app file to make apllication load it by default. Fixes #1084.
