Ok so the patch has gone out of beta.
You can get it here.

Also the NEW Q4MAX version is also available, although it seems that this was a rushed release, since the dev team wanted to make their release coincide with the patch and id gave them that opportunity.

The patch seems to fix almost every issue including gameplay and network. Plus the voice chat now seems to be working.
ID also threw in some maps.
