Sorry for the delay. Forge is alive, yes - I am the project lead. We are fixing bugs in forge/core as they are reported, but no new features planned so far in that repository. Every new feature is implemented as an add-on (we want to keep them separated from core so people can choose what they need), so that's where you will find new features. We had some contributions from some community members lately (the latest being support for embedded IDs in the JPA: New Entity command).
Please feel free to discuss in this list what features you would like to see in Forge.
