You can download the new release from ezQuake homepage.

I recommend reading the changelog and the ezQuake newspost.

I also recommend reading the upgrading part if you haven't already done so with the 1.8 releases, it contains really important instructions.

You can also continue on reporting bugs or requesting features as always.

Well that pretty much sums it all up. All I can say that this is a preferred release and everyone should update to it as soon as possible.
