 - `services.clamsmtp` is unmaintained and was removed from Nixpkgs.
 
+- The latest available version of Nextcloud is v32 (available as `pkgs.nextcloud32`). The installation logic is as follows:
+  - If [`services.nextcloud.package`](#opt-services.nextcloud.package) is specified explicitly, this package will be installed (**recommended**)
+  - If [`system.stateVersion`](#opt-system.stateVersion) is >=25.05, `pkgs.nextcloud32` will be installed by default.
+  - If [`system.stateVersion`](#opt-system.stateVersion) is >=24.11, `pkgs.nextcloud31` will be installed by default.
+  - `nextcloud30` is EOL and was thus removed.
+  - Please note that an upgrade from v30 (or older) to v32 directly is not possible. Please upgrade to `nextcloud31` (or earlier) first. Nextcloud prohibits skipping major versions while upgrading. You can upgrade by declaring [`services.nextcloud.package = pkgs.nextcloud30;`](#opt-services.nextcloud.package).
+
 - `services.eris-server` was removed from Nixpkgs due to a hostile upstream.
 
 - `prosody` gained a config check option named `services.prosody.checkConfig` which runs `prosodyctl check config` and is turned on by default.

 However, it's possible to use e.g. `httpd` by explicitly disabling
 `nginx` using [](#opt-services.nginx.enable) and fixing the
 settings `listen.owner` & `listen.group` in the
