Whatever happened to this?, bloodtype is still flagged as *development version only* on the Zdoom Wiki, whereas this thread was moved to closed feature suggestions long ago.
ZDoom hasn't been officially updated in a very very long time.
If you want the new features, then use the SVN build, which can be easily found via the wiki.
Yeah, I shouldn't have been slacking off during the first half of the year, and now getting the new website ready is taking longer than I expected (mostly to customize phpBB 3).
