 - `Prosody` has been updated to major release 13 which removed some obsoleted modules and brought a couple of major and breaking changes:
   - The `http_files` module is now disabled by default because it now requires `http_files_dir` to be configured.
   - The `vcard_muc` module has been removed and got replaced by the inbuilt `muc_vcard` module.
