They moved away from SWIG and to PyBind11. As they mention, this is going to be an annoying transition for my custom out-of-tree modules. Overall though, I'm excited for the changes.

Lots of new GUI blocks in this release. I'm especially glad to see the new eye diagram.

Also the ability to load non-WAV audio files will be nice. OGG/Vorbis and FLAC are now supported. Plus a slew of minor conveniences such as a freq shift block and scaling options in the IShort to Complex block (useful for loading recorded samples from hardware).

If only it would compile easily on my Mac. (https://github.com/ktemkin/gnuradio-for-mac-without-macports has a prebuilt 3.8 version)
