Changelog

This project follows Semantic Versioning.

v0.2.0 - 2024-12-09

This is a backwards incompatible update. The following changes are needed:

Replace all calls to Alarmist.current_alarms/0 with Alarmist.get_alarm_ids/0. This is a hard deprecation.
Update all message handling on Alarmist events to expect and use the Alarmist.Event.t(). In most usage, this means matching on :id and :state and it should simplify the handling functions.

Updates
- Simplify the API by completely abstracting away the internal implementation with uses the PropertyTables library. This will allow for further internal improvements without forcing breaking changes.
- Align the API for getting alarms with :alarm_handler. This added the Alarmist.get_alarms/0 function.
- Remove a race condition involving the use of alarm descriptions. Descriptions are sent to subscribers with the alarm status change notification now.
- Use one timestamp value for all alarms that were set at initialization time. This removes the ambiguity of whether an alarm changed a few milliseconds after Alarmist start up or was one of the original alarms.
- Report when alarms are in an :unknown state when no information is available. This is useful for the :previous_state field in alarm events.

v0.1.3 - 2024-09-26

Updates
- Don't crash on non-atom Alarm IDs. Alarmist doesn't support these yet so they're currently ignored.
