> [!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.
> ### For Systems with disabled IPv6
> This Update included some changes for NGINX, make sure to check out the updated [Disable IPv6](https://docs.mailcow.email/post_installation/firststeps-disable_ipv6/) Documentation to apply the changes if needed.

> [!WARNING]
> This update include a fixed security issue. Which can only be exploited if an attacker has access to a victims computer.
