<li>
Move most files in CBFS to GRUB memdisk, except grub.cfg and grubtest.cfg

will want to modify, which remains in CBFS.
</ul>
</li>
<li>docs/release.html Add DMP vortex86ex to list of candidates.</li>
<li>docs/release.html Add ThinkPad X201 to list of candidates.</li>
<li>New links added to docs/security/x60_security and docs/security/t60_security</li>

<li>Removed obnoxious warnings from flashing scripts, improved documentation instead.</li>
<li>scripts (all): add proper error checking (fail fast, fail early. Do not continue if there are errors)</li>
<li>buildrom-withgrub: rename image to boardname_layout_romtype.rom</li>
<li>buildrom-withgrub: don't move cbfstool, execute directly</li>
<li>resources/utilities/grub-assemble: add French Dvorak (BEPO) keyboard layout.</li>
<li>Documentation: add docs/hardware/x60_keyboard.html (show how to replace keyboard on X60/X60T)</li>
<li>Documentation: major cleanup (better structure, easier to find things)</li>
<li>
docs/release.html: Remove Acer CB5 from list of future candidates.
<ul>
<li>
Too many issues. Chromebooks are crippled (soldered RAM/storage/wifi)
and have too many usability issues for the libreboot project.
</li>
</ul>
</li>
<li>docs/gnulinux/grub_cbfs.html Major cleanup. Usability improvements.</li>
<li>hocs/gnulinux/encrypted_trisquel.html: Fixed mistakes/typo's. General improvements</li>
<li>
flash (flashrom script): remove boardmismatch=force
<ul>
<li>
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 machine. It's almost certain that most people
have upgraded by now, so remove this potentially dangerous
option.
</li>
</ul>
</li>
<li>Documentation: update compatibility list for X60T LCD panels.</li>
<li>docs/release.html: add note about X60 Tablet board in X60/X60s</li>
<li>docs/howtos/grub_boot_installer.html: small corrections</li>
<li>docs/howtos/grub_boot_installer.html: improved readability, fixed html errors</li>
<li>Documentation (macbook21 related): clean up</li>
</ul>

<h2 id="critical_tasks">
Critical tasks for future release
</h2>
<ul>
<li>
X200: only framebuffer graphics work. This is fine, since it's what most people use,
but text-mode graphics initialization is currently broken, which means that
memtest86+ will require serial output or ehci debugging.
</li>
<li>
X200: at very low brightness levels, the backlight is uneven. Fix that.
</li>
<li>
Fix remaining incompatible LCD panels in native graphics on T60.
See <a href="future/index.html#lcd_i945_incompatibility">future/index.html#lcd_i945_incompatibility</a>.
</li>
<li>i945: fix VRAM size (currently 8MB. should be 64MB). See <a href="future/index.html#i945_vram_size">future/index.html#i945_vram_size</a>.</li>
<li>
Add proper GS45 raminit for enabling all X200S and X200 Tablets to work properly. See <a href="hcl/x200.html#x200s_raminit">hcl/x200.html#x200s_raminit</a>
</li>
<li>
Look into those machines:
<ul>
<li>
ThinkPad X201 - ME ignition is an issue. Watchdog for ME is an issue. Might be possible to disable watchdog in the flash descriptor
(soft straps).
</li>
<li>
ThinkPad R400/R500/T400/T400S/T500/W500: see <a href="hcl/x200.html#new_targets">hcl/x200.html#new_targets</a>.
</li>
<li>
Lenovo G505S - might need video bios and microcode updates. These would have to be removed and/or replaced to be in libreboot
<a href="https://github.com/alterapraxisptyltd/lenovo-g505s">https://github.com/alterapraxisptyltd/lenovo-g505s</a>.
It's AMD (not Intel) based on the same design as the HP Pavillion 1035DX. No ME/AMT to worry about!
<a href"http://www.coreboot.org/User_talk:MrNuke/LTS_Candidates">http://www.coreboot.org/User_talk:MrNuke/LTS_Candidates</a>
and <a href="http://www.coreboot.org/Board:hp/pavilion_m6_1035dx#Native_graphics_init">http://www.coreboot.org/Board:hp/pavilion_m6_1035dx#Native_graphics_init</a>
</li>
<li>
F2A85-M and E350M1 (libreboot_*_headless.rom). Find cards that work without the VBIOS (load, but not execute).
</li>
</ul>
</li>
</ul>
</div>
<div class="important">
<h2 id="noncritical_tasks">
Other tasks (non-critical, but still important)
</h2>
<ul>
<li>linux 3.18 broke acpi brightness on i945. Libreboot reverted to legacy brightness for now. Look into why it
broke on 3.18 (do a git bisect).</li>
<li>
Look at vortex86ex boards. See <a href="http://libreboot.org/vortex86ex">http://libreboot.org/vortex86ex</a>.
</li>
<li>Adapt linux-libre deblob scripts for use with coreboot. Libreboot is already deblobbed
using it's own script, but updating it is still a bit too manual. linux-libre's deblob
scripts do an excellent job and (adapted) will make it much easier to maintain coreboot-libre.</li>
