proper url for emacs 24 alpha for Windows

[Xah Lee]

which is the proper url for alpha version of emacs 24 for Windows?

there's

http://alpha.gnu.org/gnu/emacs/pretest/windows/
and
http://alpha.gnu.org/gnu/emacs/windows/

the latter seems to have funny version numbers. e.g.

both of these

 emacs-20120507-r108144-bin-i386.zip         07-May-2012 03:05   57M
 emacs-20120514-r108224-bin-i386.zip         14-May-2012 08:36   57M

says
GNU Emacs 24.1.50.1 (i386-mingw-nt6.1.7601) of 2012-05-14 on MARVIN

• 24.1.50 ??
• and both having the same version?

but ones from
http://alpha.gnu.org/gnu/emacs/pretest/windows/
says
GNU Emacs 24.0.97.1 (i386-mingw-nt6.1.7601) of 2012-05-16 on MARVIN

which seems more proper.

Thanks.
