What is new with AVP in Avp-20170505-a1?

Hi,
I can see that new files are present at the address:
http://www.ms1.icculus.org/projects/avp/files/avp-20170505-a1.tar.gz
Can someone say anything about this new release?

it looks like it got cmake building and maybe a few other things that could be interesting.

As far as I remember, this contained a first pass of emscripten support, for those amused by the idea of running this game through a web browser.
