What is the status of GNU screen?

Amadeusz Sławiński, GNU Screen’s new primary upstream maintainer uploaded 2 versions this year:

• the status quo of Screen development as version 4.2.0
• the 4.2.1 that you can find in the Ubuntu repositories

From the 4.2.0 announcement:

With this I also plan to put v.4 into maintenance mode and start developing v.5 with cleaned up source code, new features

Clearly the project is not unmaintained, but as many other projects it requires contributors to fix bugs and work on new features.
