Changes for this release (latest changes first, earliest changes last)
----------------------------------------------------------------------
- grub.cfg: Added (ahci1) to list of devices for ISOLINUX parser
(CD/DVD) (this is needed for the X200 docking station).
- grub.cfg: ISOLINUX parsing is now done on all USB partitions.
- grub.cfg: Automatically switched to /boot/grub/libreboot\_grub.cfg
on a partition, if it exists.
- libreboot\_bin: added static ARM binaries for flashprog, cbfstool,
ich9gen and ich9deblob (tested on beaglebone black).
- Flashrom: removed redundant Macronix flashchip definitions (for X200
owners).
- Flashrom: added whitelist for ThinkPad X200.
- X200: fixed uneven backlight (at low levels)
- ich9macchange (new script, uses ich9gen): for changing the default
MAC address on X200 ROM images.
- ich9gen: added capability to change the default MAC address (and
update the checksum)
- ich9deblob: added new utility ich9gen: this can generate a
descriptor+gbe image without a factory.rom dump present.
- Modified ich9deblob to use a struct for Gbe, documenting everything.
- Massively updated the ich9deblob utility: re-factored everything
completely.
- Enabled cstates 1 and 2 on macbook21. This reduces idle heat / power
consumption.
- buildrom-withgrub: disabled creation of \*txtmode\*.rom for X200
(only framebuffer graphics work)
- Updated SeaBIOS (again)
- docs/install/\#flashprog\_x200: improve instructions
- Updated flashprog (again) - patches updated
- Updated GRUB (again)
- Updated coreboot (again)
- build-release: not all files were copied to libreboot\_src. fix
that.
- build-release: include cbmem (statically compiled) in libreboot\_bin
- Documentation (X200): added software-based flashing instructions
- Documentation: remove all references to the bus pirate (replaced
with BBB flashing tutorials)
- **New board:** ThinkPad X200S and X200 Tablet support added to
libreboot
- build: automatically find board names (configs) to build for
- **New board:** ThinkPad X200 support added to libreboot
- coreboot-libre config (all boards): enable USB dongle log output
(for BeagleBone Black)
- cleandeps: actually clean grubinvaders
- .gitignore: add powertop directory
- cleandeps: clean i945-pwm utility
- scripts (all): fix typos
- Documentation: general cleanup.
- builddeps-flashprog: reduce build commands to a single for loop
- scripts (all): replace unnecessary rm -Rf with rm -f
- docs/release.html: add lenovo g505s to the list of candidates
- .gitignore: add libreboot\_bin.tar.xz and libreboot\_src.tar.xz
- libreboot\_bin.tar.xz: Include utils as statically linked binaries
- This means that the user does not have to install build
dependency or build from source anymore.
- grub.cfg: Add more path checks to isolinux parser (more ISOs should
work now)
- Update SeaBIOS
- x60flashfrom5 (new), for X60 users upgrading from 5th/early release
- Update flashprog
- Update GRUB
- Updated coreboot-libre
- i945: permanently set tft\_brightness to 0xff (fixes bug on X60
where turning up brightness at max would make it loop back to
low brightness)
- getcb: Revert X60/T60 to legacy backlight controls
- The ACPI brightness patches were abandoned and obsolete.
- grub.cfg: Only load initrd.img if it exists. Add rw to linux line

- New links added to docs/security/x60\_security and
docs/security/t60\_security
- lenovobios\_secondflash: Warn if BUCTS is not present. (not a
dealbreaker. Can just pull out nvram battery/coin).
- lenovobios\_firstflash: Fail if BUCTS fails. (anti-bricking
precaution)
- Removed obnoxious warnings from flashing scripts, improved
documentation instead.
- scripts (all): add proper error checking (fail fast, fail early. Do
not continue if there are errors)
- buildrom-withgrub: rename image to boardname\_layout\_romtype.rom
- buildrom-withgrub: don't move cbfstool, execute directly
- resources/utilities/grub-assemble: add French Dvorak (BEPO) keyboard
layout.
- Documentation: add docs/hardware/x60\_keyboard.html (show how to
replace keyboard on X60/X60T)
- Documentation: major cleanup (better structure, easier to find
things)
- docs/release.html: Remove Acer CB5 from list of future candidates.
- Too many issues. Chromebooks are crippled (soldered
RAM/storage/wifi) and have too many usability issues for the
libreboot project.
- docs/linux/grub\_cbfs.html Major cleanup. Usability improvements.
- flash (flashprog script): remove boardmismatch=force
- This was put there before for users upgrading from libreboot r5
to r6, but also allows the user to flash the wrong image. For
example, the user could flash a T60 image on an X60, thus
bricking the system. It's almost certain that most people have
upgraded by now, so remove this potentially dangerous option.
- Documentation: update compatibility list for X60T LCD panels.
- docs/release.html: add note about X60 Tablet board in X60/X60s
- docs/howtos/grub\_boot\_installer.html: small corrections
- docs/howtos/grub\_boot\_installer.html: improved readability, fixed
html errors
- Documentation (macbook21 related): clean up
