Emacs 29 for Windows - snapshot @64a2b0d36fe now on GNU Alpha FTP sites

Windows "snapshot" binaries for emacs-29@64a2b0d36fe are uploading now
and should be available from your fav GNU alpha FTP mirror shortly.

https://alpha.gnu.org/gnu/emacs/pretest/windows/emacs-29/?C=M;O=D

Notes:
- I changed the file-naming convention with this version. Binary sets
are now named to include the git revision short code instead of the
date of build.
- My build script seems to work well; I'll probably start making new
snapshots pretty aggressively, as I see commits come into the emacs-29
branch during the final push to release of Emacs 29.1.
