New in 1.99:
* New relocator. Allows for more kernel support and more
straightforward loader writing.
* Handle USB pendrives exposed as floppies.
* New Automake-based build system.
* Add `sendkey' command (i386-pc only).
* ZFS support in `grub-install' and `grub-mkconfig'. Note: complete
functionality requires external ZFS implementation (available from
grub-extras).
* Support 1.x versions of mdadm metadata.
* Fix corruption when reading Reiserfs directory entries.
* Bidirectional text and diacritics support.
* Skip LVM snapshots.
* MIPS Yeeloong firmware port.
* Change grub-mkdevicemap to emit /dev/disk/by-id/ names where possible
on GNU/Linux.
* Add `grub-mkconfig' support for Xen with Linux.
* Add `grub-mkconfig' support for initrd images on Fedora 13.
* Support >3GiB and <16MiB RAM in i386-qemu.
* Add support for Cirrus 5446 and Bochs video cards.
* Load more appropriate video drivers automatically in `grub-mkconfig'.
* USB improvements, including hotplugging/hotunplugging, hub support,
and USB serial support.
* AMD Geode CS5536 support.
* Extensive updates to the Texinfo documentation.
* Add `grub-probe' support for the btrfs filesystem, permitting / to
reside on btrfs as long as /boot is on a filesystem natively supported
by GRUB.
* Handle symbolic links under /dev/mapper on GNU/Linux.
* Handle installation across multiple partition table types.
* Add `cmostest' command (i386/x86_64 only).
* Add support for DM-RAID disk devices on GNU/Linux.
* Remove `grub-mkisofs'. `grub-mkrescue' now uses GNU xorriso to build
CD images.
* `grub-mkrescue' support for EFI, coreboot, and QEMU platforms.
* Unify `grub-mkimage' source code across platforms.
* Fix VGA (as opposed to VBE) video driver, formerly a terminal driver.
* Add menu hotkey support.
* Add support for the nilfs2 filesystem.
* `grub-probe' and `grub-mkconfig' support for NetBSD.
* Support setting a background image in `grub-mkconfig'.
* Support multiple terminals in `grub-mkconfig'.
* Regexp support.
* MIPS multiboot2 support.
* Multiboot2 tag support.
* sunpc partition table support.
* Add a number of new language features to GRUB script: `for', `while',
`until', `elif', function parameters, `break', `continue', and
`shift'.
* Support nested partition tables. GRUB now prefers to name partitions
in the form `(hd0,msdos1,bsd1)' rather than `(hd0,1,a)'.
* Speed up consecutive hostdisk operations on the same device.
* Compile parts of `grub-emu' as modules.
New in 1.98 - 2010-03-06:
* Multiboot on EFI support.

@chapter Supported boot targets
X86 support is summarised in following table. ``Yes'' means that kernel works on the given platform, ``crashes'' means an early kernel crash which we hove will be fixed by concerned kernel developpers. ``no'' means GRUB doesn't load given kernel on a given platform. ``headless'' means that the kernel works but lacks console drivers (you can still use serial or network console). In case of ``no'' and ``crashes'' the reason is given in footnote.

@item Requires BIOS
@item Crashes because the memory at 0x0-0x1000 isn't available
@item EFI only
@item 32-bit and 64-bit EFI have different structures and work in different CPU modes so it's not possible to chainload 32-bit bootloader on 64-bit platform and vice-versa
@item Some modules may need to be disabled
@item Requires ACPI

PowerPC and Sparc ports support only Linux. MIPS port supports Linux and multiboot2.
@chapter Boot tests
As you have seen in previous chapter the support matrix is pretty big and some of the configurations are only rarely used. To ensure the quality bootchecks are available for all x86 targets except EFI chainloader, Appleloader and XNU. All x86 platforms have bootcheck facility except ieee1275. Multiboot, multiboot2, BIOS chainloader, ntldr and freebsd-bootloader boot targets are tested only with a fake kernel images. Only Linux is tested among the payloads using Linux protocols.
