Our good guru Daniel de Rauglaudre has released at last version 5.0 of his great genealogical software Geneweb. He's been running an experimental version on his site for at least a year now, and he has finally packaged it for many OSes. The previous stable version 4.10 was over 2 years old.
A 5.01 version is in the works. The change log is missing, but if you read the distribution list, you'll get a good grasp of what is involved.
