This entry is rather confusing:
lyx
This is the unstable development branch, and is not in use anymore. Use this only if you know want to see in what direction LyX is going (e.g. the new LyX kernel). Expect this to crash frequently.
The second and third sentences should be deleted (if I understand correctly, all current development happens in lyx-devel).
