+### Versioning
+
+Recently Microsoft decided to update the base images to alpine 3.22.
+Before 2025-11-11 the latest supported version was alpine 3.21.
+In order to support these changes the naming scheme will need to be changed.
+Going forward specefic tags will be vailable for the different versions: by example `9.0.11-alpine-21` and `9.0.11-alpine-22`.
+By default alpine 22 will be used and the older versions will be supported as long Microsoft does.
