Maybe I am too tired:
I've just compiled r8681 on Linux - that' what I was hoping for. To check, I fired it up but I can only see the version number "2.6.3" in the About-Menu. Weren't there brackets containing the release number behind this line in previous versions? Or do I exchange this with the windows versions I used with wine before?
If you compiled from a snapshot that's normal
If you compiled from svn/git, it's not normal
Bang :o , yes, I used a snapshot ::) ... Will try again soon - but I'm pretty sure this makes the difference.
