[!CAUTION] Please create a backup before updating, as several internal components got major changes

FTS Changes

Due to the FTS change, all previous Solr Indices are unused. Once updated, FTS will be disabled automatically. If you had it enabled, change the Variable SKIP_FTS from y to n.

Nextcloud Removal

This update removes the integrated Nextcloud helper-script. Any running installations with the Nextcloud implementation are unsupported. Please consider a switch to a native Nextcloud installation instead.

[!IMPORTANT]

UI changes (related to netfilter-mailcow)

If you used the external Fail2Ban List Endpoint, you have to change the Endpoint URL to the one displayed in mailcow UI, as it has changed with this update.
