The Mandrakelinux 10.2 Beta 1 is now available on FTP mirrors, as well as via bittorrent. Three ISO images of 700 MB, 1700 packages, are in the Mandrakelinux/devel/iso/10.2/i586 on most Mandrakelinux mirrors.
Packages are also available directly from the FTP tree, if you want to update your system without reinstalling. Find all the media in Mandrakelinux/devel/10.2/i586 on the mirrors.
If you stop reading now and rush to test, only remember to report your bugs on Bugzilla, and perform the tests available in the Testzilla section. The Community Wiki also contains worthwhile info.
