Latest NextcloudPi version

I upgraded my ncp server to v1.16.0 a few weeks ago but cannot find any documentation for any version past v1.15.3. Is 1.16.0 the latest or is it a non stable version?

Thanks

Presently;

Latest version of NextCloudPi is v1.15.3 docs

Latest stable version of Nextcloud is 16.0.3 manuals

So is v1.16.0 a beta version?

Iā€™m still confused as to why my server upgraded to v1.16.0. Does anyone else get notifications to upgrade to v1.16.0 on their versions of NextcloudPi?
