redstone99/hass-alert2 v1.19.1 on GitHub

Update to release v1.19 which had a potential issue during migration from v1.18.
v1.19 changes:

generator_name is now optional. If not specified, no entity for the generator itself will be created.
New field, exception_ignore_regexes allows you to not send notifications for exceptions that happen if the exception + stack trace matches any of the regexes specified. Intended to suppress notifications due to known faulty components. Only allowed for alert global_exception spec and any alert with name="unhandled_exception" (intended for use by people writing components and using alert2 create_task)
Hysteresis state now preserved across HA restarts.
Fix bug where a hysteresis alert could get stuck on if HA restarted between when the alert turned on and would turn off.
