You can fix bugs in a release candidate.
Yes, but as mentioned in another mail thread, its better to keep it in head until ready to make the RC (which now that the windows release it out, and hopefully more people playing it, a few bugs should be reported and fixed before the RC goes out).\
There was a big package mess:
* Playable only on some distributions.
* Playable only on intel processors
* No Maps or campaigns in the package.
Yes, the package was a mess. But I'll make sure alpha 23 has all the right stuff (I'll release alpha23 for windows and mandriva at the same time).--
