API Changes

This release requires that all events have a unique ID. Until recently, the event identity was checked by comparing the raw data objects. However, using duplicate IDs is usually a sign of an error or bad design and unique IDs are now enforced:

  • [Scheduler] Checking for duplicate IDs when loading events from events.list. (build 3447)
  • [Scheduler] requires a unique ID. (build 3466)

The Angular version has been enforcing unique IDs since the first release.
