2.3.0

New Home Assistant "button" is now available which can be used to mark all unread messages (school communication) as read.

This number of unread messages is also shown as the smartschool mobile app counter. When many message are received, this number is hard to get down (nee to open each message one by one).

Witht he new button, all can be marked as read at once.

Also small cleanup in logging to make sure all smartschool is details are logged in custom_component.smartschool.
