“Instant WordPress Beta Build”
I grabbed the title from a post on « planetOzh: “the link at the very bottom of the page that will send you a fresh build in a zip archive. Handy for when you don’t have an SVN install to play with.”
Point is that you don’t need to use SVN if you want the newest version of WordPress.
At the very bottom of trac.wordpress / trunk we find the link that Ozh mentioned.
And if you want a up-to-the-minute GZip, there’s the directory at static.wordpress.org / builds.
