Matthias Clasen has written the best overview and it is in the official channel for news from Gnome. Link above for the official project release notes. I am a long time user of Gnome and have recently become a huge fan once again.
I have been using Gnome since version 2 in 2003. A long hiatus of XFCE as GTK, Web, and Qt were all finding their way. Fortunately we now have a complete package of Gnome for use with all modern machines.
Gnome Shell and Mutter has come a long way and all those reports are hosted here:

In all due respects, this is the best Desktop I've ever run on GNU/Linux and I foresee it taking the lion's share of Linux Desktop as well as becoming an enterprise OS with the help of Canonical and IBM.

IBM will be tough competition, but I welcome it.
Thank you #gnome40 contributors.
