How is is going the developing in Gatein 4? I see the github branch is not used since one year about. gatein/gatein-portal at 4.0.0 · GitHub . Is the developing stopped? I see the in the eXo repository a branch exoplatform/gatein-portal at release/4.2.0-M2-PLF · GitHub much worked. Are the sources moved there? Does jboss community continue to support Gatein?
I don't know about the road map of gatein 4.0.0 but gatein branches at exoplatform repository.
exoplatform/gatein-portal/tree/stable/4.2.x-PLF is dedicated to eXo Platform 4.2. It is still based on https://github.com/gatein/gatein-portal/tree/3.5.x/. The branch exoplatform/gatein-portal/tree/release/4.2.0-M2-PLF is temporary during the release of gatein 4.2.0-M2-PLF for eXo Platform 4.2.0-M2.
