Complete changelog:
https://github.com/EGroupware/egroupware/compare/23.1.20250902…23.1.20251021
New functions / preferences or other important things:
- Mail/Sieve: support numeric comparison to a header e.g. “X-Spam-Score”
Mail filters can now apply a numerical comparison to headers.
For example, ‘X-Spam-Score’ can be used to evaluate the spam rating of an email and filter it into a subfolder once it reaches a certain value.
- Calendar: allow adding resources to subscribed calendars e.g. for migrating a ressource-calendar to EGroupware
It is now possible to assign resources as additional participants to subscribed calendars. This is helpful when migrating resource calendars.
- API/Authentication: new App-password backend to deny authentication with the real password, to force usage of tokens for Cal/CardDAV or eSync
It is now possible to enforce app passwords for authentication in the EGroupware Setup for CalDAV/CardDAV and eSysnc (ActiveSync). This means that it is no longer possible to log in there with normal access data.
- LDAP/ADS: allow to import aliases from AD or LDAP, incl. download of an .ldif file to first set them in the directory
It is now possible to import aliases from AD/LDAP and export an .ldif file.
