Just a notice that yafray 0.0.5 is out. However, it's considered unstable: "After hidding the new features for a long time we finally release this version. You may have seen some of this things in previous code previews. This is in fact an unstable release. There are some not fully tested new things that could fail with some scenes. Also halo in spot light could not work properly. The new features need a lot of doc and tutorials. I just began to write a bit about them. You can find the changes explained in the ChangeLog Notice that there are links to the wiki doc. With a tutorial in the new GI scheme and an example scene." I do not have ebuild skills, otherwise I would submit.
Needs gcc 3.3.2 to compile. I was unable to compile it with gcc 3.2.3 and confirmed with the author.
Cannot be tested, zero activity as well.
