Warning: Keep in mind that this is the bleeding edge of development.
NOTE: The server might accidentally disconnect your download connection before it is complete, especially with the larger downloads, depending on your ISP and how fast your Internet connection is. If you have trouble downloading the larger files, or any files here, please try a third-party download manager such as flashget or downthemall (a Firefox extension).

The community provides binaries, though these binaries are often quickly outdated.
