Changes to the calendar can affect various things in Koha, including due dates, fine calculation and sending of overdue notices. Sometimes a strange behavior can only be explained by holidays having been added or removed. In order to "debug" these issues, it would be great if changes to the calendar were logged.
Great idea. +1
This is a great idea - we have definitely encountered the strange behavior caused by adding/removing holidays. A calendar log would make tracking down these issues much quicker. +1
