It seems there used to be a GeoServer extension to support "Versioned Web Feature Services" (https://github.com/boundlessgeo/geoserver-2.1.x/tree/master/extension/wfsv).
Interestingly I can find no information about a versioning extension to the WFS standard, or about this GeoServer extension online.
So using GeoServer 2.13+, how do folks implement versioning or at least an audit log for WFS-T transactions? For example how do you track changes to a dataset maintained by multiple members of a team? This could then lead into publishing workflows etc, but I'm trying to wrap my head around how to implement a versioning workflow first ..
