+## Semver versioning within this recipe
+
+The recipe version itself is updated according to the following semver
+rules, following
+[How are recipes versioned](https://docs.coopcloud.tech/maintainers/handbook/#how-are-recipes-versioned):
+These describe the minimum required bump for a given kind of change. 
+The actual impact of any change (an image update or, e.g. a compose or config change) 
+should always be considered, and the recipe version can always be bumped higher 
+than the guideline below to match the impact of the change.
+ 
+- For updates of the image in the app container (nextcloud), we match the 
+  recipe version bump to at least the image version bump.
+- Other containers in this recipe are considered dependencies of the app container 
+  unless they expose additional functionality directly.
+- For image updates of dependency containers, we judge the recipe version bump 
+  from the perspective of the app itself, but a minor or major update of a 
+  dependent container is always reflected by at least a minor recipe version bump 
+  to indicate a substantial update under the hood.
+
+Temporary exception:
+- In the past, there have been issues with upgrades from database containers 
+  (before the `pgautoupgrade` image and `MARIADB_AUTO_UPGRADE` setting). 
+  We continue treating a major update of a database container (postgresql, mariadb) 
+  as a major recipe bump until that database has had two consecutive major upgrades 
+  with no issues reported, building trust in its automatic upgrade. 
+  Once that trust is established for a given database, we continue with the 
+  default guidelines above.
+
+WARNING:
+When moving to a new major version of a dependency, the maintainer needs to make
+sure that the version is supported!
+Example: in June 2026, MariaDB got updated to version 12, but nextcloud suggests
+only up to version 11.8 for best performance.
