 - The `lsh` package and the `services.lshd` module have been removed as they had no maintainer in Nixpkgs and hadn’t seen an upstream release in over a decade. It is recommended to migrate to `openssh` and `services.openssh`.
 
+- `opencv2` and `opencv3` have been removed, as they are obsolete and
+  were not used by any other package. External users are encouraged to
