[Koha] Getting a newer version of Koha

[George Adams]

(Koha 3.0alpha, (Gentoo) Linux 2.6.24, MySQL 5.0.56)

I've seen some terms thrown around like "latest snapshot", "git" and such
that seems to indicate it's possible to get a newer version of Koha
than 3.0alpha.

I found my way to
http://git.koha.org/cgi-bin/gitweb.cgi?p=Koha;a=summary , but I'm not
sure what to do there.  Clicking on any of the links labeled "snapshot"
seems to trigger a really big download, though.

So, to get the latest version of Koha, should I just download the top
"snapshot" link?  Or is there a better way to do it?

(Is there a revised release date for the beta, BTW?)

Thank you.
