I really can't take credit... the NewOS archives are named like that (ok, year, month, day) and I've been grabbing updates of it that way for over a year.
It really helps silly people like me so we don't get confused at which archive is the new one.
Oh, and you can avoid updating the web page all the time if you just point the link to a directory with the latest files and have it set up for FTP. Then set up scripts to do the file updates automatically when your ready to distribute a new version.
FWIW, never versions of GRUB support display of a splash screen image. The version of AROS GRUB I looked at didn't appear to have it. If you incorporate that you could bring up the AROS logo while it's booting. Not because we need it... but just because it would look cool!
