"Release" means that a new coreboot git revision with substantially different code has been adapted for libreboot.
"Revision" means a modification to an existing release, where the result is insubstantially different from what preceded it.
The 1st, 2nd, 3rd and 4th releases were really just older revisions of the 5th release.
For historical reasons (and to avoid confusion), these are still called 'releases' instead of correcting the mistake.
6th release (pre-release, 5th beta)
Released 2014 July 11th (pre-release) 1st beta
Revised (pre-release, 2nd beta) 2014 July 16th

If flashing on an X60 then note that you might want to enable wifi and trackpoint after
booting libreboot the first time (meaning, **after** you powered off and subsequently booted again).
See ../docs/index.html#x60_wifi and
../docs/index.html#x60_trackpoint for how to do that.
Binaries (for flashing) (right-click save as, or use wget)
Machines no longer supported (compared to previous release):
All previous machines still supported!

Documentation: added information about how to use the 'get' scripts in libreboot_meta.tar.gz (to generate libreboot_src.tar.gz)
Documentation: mention that meta doesn't create libreboot_src/ directory, but that libreboot_meta itself becomes the same.
Documentation: advise to rename libreboot_meta to libreboot_src after running 'getall'.
Annotated the 'builddeb' script, to say what each set of dependencies are for.
Separated bucts/flashrom builddeb sections into separate scripts: builddeb-flashrom, builddeb-bucts.

Created patched version of the relevant source files and added it into resources/cbfstool/patch
see coreboot/util/cbfstool/rmodule.c and then the patched version in resources/cbfstool/patch/rmodule.c
see coreboot/src/include/rmodule-defs.h and the rule in 'build' for including this in ../libreboot_bin/cbfstool_standalone
Added instructions to 'build' script for applying this patch to the cbfstool_standalone source in libreboot_bin
Added instructions to 'build' script for then re-compiling cbfstool_standalone in libreboot_bin after applying the patch
Added a 'builddeps-cbfstool' script (in src, but only used in bin and put in bin by 'build') that compiles cbfstool_standalone in libreboot_bin (make), moves the cbfstool and rmodtool binaries into libreboot_bin/ and then does 'make clean' in libreboot_bin/cbfstool_standalone
Updated the 'build' script to put 'builddeps-cbfstool' in libreboot_bin
Updated the 'build' script in the cbfstool (standalone) part to accomodate the above.
Documentation: added notes about cbfstool (standalone) in libreboot_bin

it's FRU P/N 41W1478 (on T60 14.1") so this was added to the docs.
it's P/N 42T0078 FRU 42T0079 or P/N 41W1338 (on T60 15.1") so this was added to the docs.
Documentation: added information about names of LCD panels for T60 to the relevant parts of the documentation.
Documentation: added information (with pictures) about the differences between T60 with Intel GPU and T60 with ATI GPU.
Documentation: added pictures of keyboard layouts (US/UK Qwerty/Dvorak) to the ROM list, to let the user compare with their own keyboard.

Added to docs/index.html#serial
Revisions for 2nd beta (2014 July 16th)
Deleted all git-related files from the coreboot directory. This was necessary because
with those it is possible to run 'git diff' which shows the changes made in the form
of a patch (diff format); this includes the blobs that were deleted during deblobbing.
Revisions for 3rd beta (2014 July 20th)
Fixed typo that existed in 2nd beta where the release date of the 2nd beta was listed as being in year 2016, when in actual fact it was 2014.
Documentation: added (preliminary) details about (rare) buggy CPU's on the ThinkPad T60 that were found to fail (instability, kernel panics, etc)
without the microcode updates.

Re-factored those scripts (made easier to read/maintain): build-x60, build-x60t, build-t60, build-macbook21
Reduced the number of grub configs to 2 (or 1, for macbook21), the build scripts now generate the other configs at build time.
Deleted build-x60, build-x60t, build-t60, build-macbook21 and replaced with intelligent (generic) buildrom-withgrub script
Updated build to use buildrom-withgrub script for building the ROM images.
coreboot.rom and coreboot_serial.rom renamed to coreboot_usqwerty.rom and coreboot_serial_usqwerty.rom
coreboot_dvorak and coreboot_serial_dvorak.rom renamed to coreboot_usdvorak.rom and coreboot_serial_usdvorak.rom
Renamed coreboot*rom to libreboot*rom
Made flash, lenovobios_firstflash and lenovobios_secondflash scripts fail if the specified file does not exist.
Updated all relevant parts of the documentation to reflect the above.
Replaced background.png with background.jpg. added gnulove.jpg. (resources/grub/background/)
Updated buildrom-withgrub to use background.jpg instead of background.png
Updated buildrom-withgrub to use gnulove.jpg aswell
Updated resources/grub/config/macbook21/grub*cfg to use gnulove.jpg background.
Updated resources/grub/config/{x60,t60,x60t}/grub*cfg to use background.jpg background.
Documentation: updated docs/index.html#grub_custom_keyboard to be more generally useful.
nvramtool:
Updated builddeps-coreboot script to build it
Updated build script to include it in libreboot_bin
Documentation: added docs/howtos/x60_security.html (security hardening for X60)
Revisions for 4th beta (2014 July 29th)

MacBook2,1 tested (confirmed)
macbook21: Added script 'macbook21_firstflash' for flashing libreboot while Apple EFI firmware is running.
Documentation: macbook21: added software-based flashing instructions for flashing libreboot while Apple EFI firmware is running.
Reduced size of libreboot_src.tar.gz:
Removed .git and .gitignore from grub directory (libreboot_src); not needed.
Removing them reduces the size of the archive (by a lot). GRUB development should be upstream.
Removed .git and .gitignore from bucts directory (libreboot_src); not needed.
Removing them reduces the size of the archive. bucts development should be upstream.
Removed .svn from flashrom directory (libreboot_src); not needed.
Removing it reduces the size of the archive. flashrom development should be upstream.
Added ROM's with Qwerty (Italian) layout in GRUB (libreboot*itqwerty.rom)
Added resources/utilities/i945gpu/intel-regs.py for debugging issues related to LCD panel compatibility on X60 Tablet and T60. (courtesy of Michał Masłowski)

Documentation: added preliminary information about preventing/mitigating cold-boot attack in x60_security.html and t60_security.html
Documentation: added info to ../docs/index.html#macbook21 warning about issues with macbook21
Documentation: X60/T60: added information about checking custom ROM's using dd to see whether or not the top 64K
region is duplicated below top or not. Advise caution about this in the tutorial that deals with flashing on top
of Lenovo BIOS, citing the correct dd commands necessary if it is confirmed that the ROM has not been applied with
dd yet. (in the case that the user compiled their own ROM's from libreboot, without using the build scripts, or if they forgot to use dd, etc).
Split resources/libreboot/patch/gitdiff into separate patch files (getcb script updated to accomodate this change).
Re-added .git files to bucts
Fixed the oversight where macbook21_firstflash wasn't included in binary archives
Corrections to 5th beta (2014 August 2014)
Fixed typo where revision list for 5th beta was listed as March 11th 2014, when in fact it was August 11th 2014
Fixed incorrect grub.cfg that was actually placed in resources/grub/config/x60/grub_usqwerty.cfg which broke the default GRUB menu entry on X60
Other tasks (to be completed before declaring the initial stable release)
TODO: Submit 3D fix (for X60/T60/macbook21/X60T on kernel 3.12+) upstream for 5320 changeset.
TODO: Re-tooled linux-libre deblob scripts for use with coreboot. Deblobbing is already complete; completion of this additional task will simply make future deblobbing work easier.
TODO: Remove mention of blob/3rdparty repository in Kconfig
TODO: Modified coreboot to make wifi and trackpoint be enabled by default on the ThinkPad X60 (so no need for nvramtool)
TODO: added this as a patch under resources/libreboot/patch/
(Remove from or add comment in the documentation the notes about disabling wifi/trackpoint)
TODO: Modify coreboot so that tft_brightness is 0xff by default (for fixing the looping issue automatically)
TODO: Modify the Kconfig options in coreboot so that the (non-existent, deleted) microcode is never loaded when building.
TODO: Ask Mono what license he wants to use for his pages (see notes in docs/index.html#macbook21) and then include a copy in the relevant part of the documentation. (note: the backups are not included for now, for this exact reason)
TODO: Retroactively GPG-sign the final revisions of each previous release. (SHA512 sums aswell).
TODO: Tested all of the remaining untested LCD panels under docs/index.html#supported_t60_list
TODO: Documentation: macbook2,1: Show how to physically remove the built-in webcam (which doesn't work unless you install a non-free driver)
TODO: Documentation: macbook2,1: Check if there is another webcam to replace it that can work without requiring any non-free drivers.
TODO: T60 15" QXGA (2048x1536): fixed issue where GRUB wouldn't show any graphics.
It might be the same issue I ran into with Paul on the X60 (not enough memory being allocated) since the same code works on T60 SXGA+ and UXGA, where GRUB actually display graphics.
This should be done in coreboot and backported into libreboot. See 5320 and 5345 on review.coreboot.org
For now, see if lowering GRUB's resolution works (as a workaround) since everything (GNU/Linux) works after that.
TODO: Documentation: added as many links as I could find, to datasheets and schematics for macbook21/x60/t60 (i945 chipset, EC info for x60/t60/macbook21)
TODO: Go over the documentation, and find the parts that are not accessible: eg, improve the docs to be friendly for colour-blind people.
TODO: the X60 unbricking tutorial could use some work. It currently has lots of red and green, for instance. Consider highlighting specific parts of pictures in bold zig-zagged white lines instead of straight red lines.
TODO: Documentation: Added (replicated) the same level of logs (from default firmware) that Mono did for macbook21, for t60/x60/x60t
TODO: Documentation: updated the X60 unbrick tutorial to use the 5-pin method instead (safer / less dangerous).
TODO: Documentation: Add a "development guide" for how to maintain libreboot ('get' scripts, deblob scripts, associated files under ./resources and so on)
TODO: Investigate high boot speeds on X60/T60/macbook21
TODO:https://wiki.archlinux.org/index.php/TLP (example article) a user
mentioned that this also removes the high-pitched noise (like powertop does). Must look into this.
"set pager=1" is set in grub.cfg, for less-like functionality
The "Parse" options read ./isolinux/isolinux.cfg on a CD or USB,
and automatically converts it to a grub config and switches to the boot menu of that distro.
This makes booting ISO's *much* easier than before.
