0.14.1

  • Change the way modules are autodiscovered (use Django utility). It should work now with new style apps.

0.14.0

  • Added index on the stored_entity_id field which fixes performance issue when there are many events. It requires migration, version change reflects that.

0.13.4

  • Switched to schema_version = None default when deserializing events without schema_version.

0.13.3

  • Stopped overriding schema_version if it exists.
  • Started passing all event attributes to event constructor during deserialization. This allows to handle event structure migration ("upcasting") in each event's constructor: one can modify kwargs before calling super().__init__.

0.13.2

  • Made @abstract non inheritable: now only classes explicitly marked with the @abstract decorator are abstract. Their subclasses are not. This was always the intended behavior.

0.13.1

  • Switched to adding schema_version to event objects themselves instead of just transcoded events. This way events will pass validation if their Avro schemas require schema_version.

  • Renamed setting responsible for the above feature from EVENT_TRANSCODER.ADDS_EVENT_VERSION_TO_DATA to ADDS_SCHEMA_VERSION_TO_EVENT_DATA.

0.13.0

  • Renamed Event.schema_version to Event.version.
  • Started setting Event.version based on schema file with the highest number.
  • Added event version to stored event envelope under the event_version key.
  • Added setting to add event version to event data as well (see "Event version" section in README).

0.12.0

  • Started automatically choosing Avro schemas with the highest version (based on file names on disk).

  • Changed way how event type string is computed. For example, given User aggregate and Created event, now it would be "user_created" (while in older versions that would be simply "Created" which sometimes is not sufficient enough). Moreover it is now possible to override that with event_type attribute set on an event class.

0.9.4

  • Made DomainEvent.metadata optional during serialization (PR #10).

0.9.3

  • Fixed exception when DomainEvent.metadata is not defined on saving to event store. PR#7

0.9.2

  • When attempt to create an aggregate using ID of existing one, esdjango.exceptions.AlreadyExists error would be raised. NOTE: This is possibly a breaking change: previously Django's standard IntegrityError was raised.
