Comment:
Relevant sections of release notes with my annotations:

> NOTE: The 4.0.0 Release of SCons dropped Python 2.7 Support

This is what we want largely. Need to test build of packages using scons because the build scripts are literally python files.

> - Allow user specified location for vswhere.exe specified by VSWHERE.
> NOTE: This must be set at the time the 'msvc' 'msvs' and/or 'mslink' tool(s) are initialized to have any effect.

Does not apply to us.

> - Resolve Issue #3248 - Removing '-Wl,-Bsymbolic' from SHLIBVERSIONFLAGS
> NOTE: If your build depends on the above you must now add to your SHLIBVERSIONFLAGS

Might apply to us? We will see during rebuild I guess.

> - Fixed Github Issue 3628 - Hardcoding pickle protocol to 4 (supports python 3.4+)
> and skipping Python 3.8's new pickle protocol 5 whose main advantage is for out-of-band data buffers.
> NOTE: If you used Python 3.8 with SCons 3.0.0 or above, you may get a a pickle protocol error. Remove your
> .sconsign.dblite. You will end up with a full rebuild.

Does not apply to us (only ever used python2).
