* ARM U-Boot and EFI ports.
* Reorganise platform-dependent code in utilities to avoid #ifdef mess.
* AROS and Haiku support for userspace utilities.
* Xen PV port.
* Fix EFI stack alignment.
* ARM64 EFI port.
* On Linux, read partition start offsets from sysfs if possible.
* New grub-macbless utility, and better integration with Mac firmware in
grub-install.
* Support Yeeloong 3A.

* Support network boot with Oracle sun4v vnet devices.
* Added SAS disks to the IEEE 1275 Open Firmware device list.
* Try multiple methods for TSC (timestamp counter) calibration - PIT, pmtimer,
EFI Stall. If everything fails, use hardcoded frequency 800MHz.

* Map UEFI Persistent Memory to E820 persistent memory.
* New Xen loader on ARM64.
* Respect alignment requirement for block device IO buffers on EFI.
* Security:
* Add optional facility to enforce that all files read by the core image
from disk have a valid detached digital signature.
* Performance:
* Avoid costly division operations in many places.
* New boot time analysis framework (`./configure --enable-boot-time').
* Initialise USB ports in parallel.
* New `testspeed' command to test file read speed.
* Speed-up gfxterm by storing intermediate results in more compact format.
* Lazy LVM/mdraid scan.
* Disk hints.
* Scripting:
* New `eval' and `tr' commands.
* grub-script-check fails on scripts containing no commands.
* Installation and other utility improvements:
* Add option to compress files on installation or image creation.
* Using grub-reboot no longer requires setting `GRUB_DEFAULT=saved'.
* Support probing EFI System Partition (requires os-prober >= 1.58).
* Fix inconsistent use of `GRUB_CRYPTODISK_ENABLE' and
`GRUB_ENABLE_CRYPTODISK'; the latter is now used consistently.
* grub-mount handles symbolic links to directories.
* Support disabling submenus with `GRUB_DISABLE_SUBMENU' configuration key
for grub-mkconfig.
* grub-install, grub-mknetdir, grub-mkrescue, and grub-mkstandalone
rewritten in C. They should now work in supported non-Unix-like
environments.
* Native mingw support.
* Ability to install on EFI under windows.
* Reorganise timeout handling using new `timeout_style' environment
variable and `GRUB_TIMEOUT_STYLE' configuration key for grub-mkconfig.
Menu hotkeys pressed during a hidden timeout now boot the corresponding
menu entry immediately.
* New `file' command and grub-file utility to check file types.
* New syslinux configuration file parser.
* Set menu entry class to primary OS name returned by os-prober to display
OS specific icon.
* On Linux x86 detect EFI word size in grub-install and automatically select
correct platform (x86_64-efi or i386-efi) to install. Requires Linux kernel
4.0 or higher.
* Build system:
* Remove all uses of nested functions; GRUB no longer requires an
executable stack.
* Fix documentation build with Texinfo >= 5.1.
* More robust and documented cross-compiling support.
* Partial clang support for some platforms (experimental).
* Partial mingw64 x86_64-efi compile support (highly experimental).
* Partial mingw32 i386-* (other than already present i386-pc)
compile support (highly experimental).
* Support for grub-mkpasswd on Windows.
* Eliminate the use of AutoGen. This allowed some performance
improvements to the build system.
* Remove variable length arrays.
* OpenBSD compile and tools support (NetBSD and FreeBSD were already supported).
* Fix build with FreeType >= 2.5.1.
* Make gentpl.py compatible with Python 3. It now requires at least
Python 2.6.
* modinfo.sh contains build information now.
* Added many new tests to improve robustness.
* Target is built without libgcc now. Necessary builtins are reimplemented
directly. This removes requirement for target-specific runtime on build
system.
* emu libusb support removed (was broken and unmaintained).
* powerpc64le compile support.
* Use fixed timestamp when generating GRUB image for reproducible builds.
* Verify at build time that modules contain only supported relocations and their
structure matches what boot-time module loader expects.
* Do not require fonts on powerpc-ieee1275.
* Revision control moved to git.
