GRUB 2.00 Release Candidate 1 was uploaded to the GNU.org FTP server on Saturday. On the GRUB development list was then a brief message.
Hello, all. I'm proud to introduce 2.00~rc1 to you.The GRUB 2.00 release didn't come on Monday, but there's been some technical follow-up messages since the RC1 announcement so they may still be addressing last minute issues.
It's available as
As far as I'm aware all issues have been either postponed or resolved correctly, so I'll release 2.00 on Monday. Give ~rc1 a spin over the weekend and report any issues.

GRUB 2 is a complete rewrite compared to GRUB Legacy and has been in development for more than a decade without seeing a GRUB 1.00 release. Among the many new features to GRUB2 is Btrfs file-system support, ZFS support, using ACPI to shutdown where possible, a new relocator, a new build system, support for new platforms like the MIPS Yeeloong, improved video card support, menu hot-key support, support for booting XNU (the MacOS X kernel), many new commands, EFI handling, improved ATA support, and a whole lot more.
Embedded below is the official change-log found within the GRUB2 source package that covers the major features that happened during the GRUB 1.9x development releases since the first GRUB 1.90 release back in 2005. Look for the official GRUB 2.00 release any day now.
