  - http://review.coreboot.org/#/c/5324/ (merged)
- Documentation: removed the section about tft_brightness on X60 (new
  code makes it obsolete)
- Removed all patches from resources/libreboot/patch/ and added new
  patch: 0000_t60_textmode.git.diff
- Updated getcb script and DEBLOB script.
- Updated configuration files under resources/libreboot/config/ to
  accomodate new coreboot version.
- Removed grub_serial*.cfg and libreboot_serial*.rom, all
  configs/rom's are now unified (containing same configuration as
  serial rom's from before).
  - Documentation: updated ../docs/index.html#rom to reflect the above.
- Updated GRUB to new version from August 14th, 2014.
- Unified all grub configurations for all machines to a single
  grub.cfg under resources/grub/config/
- Updated flashrom to new version from August 20th, 2014
- Added getseabios and builddeps-seabios (builddeps and getall were
  also updated)
  - Added instructions to 'buildrom-withgrub' to include bios.bin.elf
    and vgaroms/vgabios.bin from SeaBIOS inside the ROM.
- Added seabios (and sgavgabios) to grub as payload option in menu
- Disabled serial output in Memtest86+ (no longer needed) to speed up
  tests.
  - MemTest86+ now works properly, it can output on the laptop screen
    (no serial port needed anymore).
- Added getgrubinvaders, builddeps-grubinvaders scripts. Added these
  to getall and builddeps.
  - Added GRUB Invaders menu entry in resources/grub/config/grub.cfg
- Added rules to builddeps-coreboot to build libpayload with
  TinyCurses. (added appropriate instructions to cleandeps script).
- Commented out lines in resources/grub/config/grub.cfg for loading
  font/background (not useful anymore, now that GRUB is in text-mode).
- Commented out lines in buildrom-withgrub that included
  backgrounds/fonts (not useful anymore, now that GRUB is in
  text-mode).
- Added resources/utilities/i945-pwm/ (from
  git://git.mtjm.eu/i945-pwm), for debugging acpi brightness on i945
  machines.
  - Added instructions for it in builddeps, builddeps-i945pwm,
    builddeb and cleandeps
- 'build' script: removed the parts that generated sha512sum manifests
  (not needed, since release tarballs are GPG-signed)
- 'build' script: removed the parts that generated libreboot_meta
  directory (not needed anymore, since _meta will be hosted in git)
  - Updated ../docs/index.html#build_meta (and other parts of
    documentation) to accomodate this change.
- Documentation: simplified (refactored) the notes in
  ../docs/index.html#rom
- 'build' script: removed the parts that generated libreboot_bin and
  added them to a new script: 'build-release'
  - Documentation: ../docs/index.html#build updated to reflect the
    above.
- Removed 'sudo' from builddeb, builddeb-flashrom, powertop.trisquel6
  and builddeb-bucts scripts (assuming that the user has it is a
  really bad idea).
- Added all gcry_* modules to grub (luks/cryptomount): gcry_arcfour
  gcry_camellia gcry_crc gcry_dsa gcry_md4 gcry_rfc2268 gcry_rmd160
  gcry_seed gcry_sha1 gcry_sha512 gcry_twofish gcry_blowfish
  gcry_cast5 gcry_des gcry_idea gcry_md5 gcry_rijndael gcry_rsa
  gcry_serpent gcry_sha256 gcry_tiger gcry_whirlpool
- Added GNUtoo's list of GRUB modules (includes all of the gcry_*
  modules above), cryptomount should be working now.
- Removed builddeb-bucts and builddeb-flashrom, merged them with
  builddeb (../docs/index.html updated accordingly)
- Removed buildpac-bucts and buildpac-flashrom, merged them with
  buildpac (../docs/index.html updated accordingly)
- Renamed builddeb to deps-trisquel (../docs/index.html updated
  accordingly)
- Renamed buildpac to deps-parabola (../docs/index.html updated
  accordingly)
- Documentation: removed all parts talking about build dependencies,
  replaced them with links to ../docs/index.html#build_dependencies
- Documentation: emphasized more strongly on the documentation, the
  need to re-build bucts and/or flashrom before flashing a ROM image.
- build-release: flashrom, nvramtool, cbfstool and bucts are no longer
  provided pre-compiled in binary archives, and are now in source form
  only. (to maximize distro compatibility).
- Documentation: added ../docs/howtos/encrypted_trisquel.html showing
  how to setup a fully encrypted Trisquel installation (including
  /boot) and boot it from the GRUB payload.
- 'build' script: replaced grub.elf assembly instructons, it's now
  handled by a utility added under resources/utilities/grub-assemble
- Moved resources/grub/keymap to
  resources/utilities/grub-assemble/keymap, and updated that utility
  to use it
- Documentation: removed useless links to pictures of keyboard layouts
  and unmodified layouts.
- Removed all unused fonts from dejavu-fonts-ttf-2.34/ directory
- 'buildrom-withgrub' script: updated it to create 2 sets of ROM's for
  each machine: one with text-mode, one with coreboot framebuffer.
- Documentation: updated ../docs/index.html#rom to reflect the above
- Deleted unused README and COPYING file from main directory
- Removed some rm -rf .git* instructions from the get* scripts and
  moved them to build-release script
- Split up default grub.cfg into 6 parts:
  extra/{common.cfg,txtmode.cfg,vesafb.cfg} and
  menuentries/{common.cfg,txtmode.cfg,vesafb.cfg}
  - buildrom-withgrub script uses these to generate the correct
    grub.cfg for each type of configuration.
- grub_memdisk.cfg (used inside grub.elf) now only loads grub.cfg from
  cbfs. It no longer enables serial output or sets
  prefix. (menuentries/common.cfg does instead)
- resources/grub/config/extra/common.cfg, added:
  - insmod instructions to load those modules: nativedisk, ehci, ohci,
    uhci, usb, usbserial_pl2303, usbserial_ftdi, usbserial_usbdebug
  - set prefix=(memdisk)/boot/grub
  - For native graphics (recommended by coreboot wiki):
  - gfxpayload=keep
  - terminal_output --append gfxterm
  - Play a beep on startup:
  - play 480 440 1
- Documentation: added note about 'fb=false' workaround for text-mode
  debian-installer (Trisquel net install) to
  ../docs/howtos/grub_boot_installer.html
- Documentation: updated ../docs/howtos/grub_cbfs.html to make it
  safer (and easier) to follow.
