    This is not a beta release. This is an alpha release for 9.08.

    5/5 for me

    but of course need better UI, because we are not in Win98 era... ;p

    Dead end, eh?! Riiight...

    So that is why Adobe switched compressing its CS from WinRAR to 7-Zip, and Microsoft adopted 7-Zip for its Silverlight distribution?

    This would be more authoritative place for compression ratings, where 7-Zip isn't doing so bad:

    I mainly use archivers for archiving multimedia contents, and even Winrar with the lowest compression beats 7-zip on highest compression. Taking that and the cluncky UI makes 7-zip more or less useless, and so it will remain for the rest of the time. It's a dead end project.

    Interface is a bit outdated. Not very user friendly but looks promising.

    Here is a gist from the forums regarding why version jump. Not much explained though.
