Upcoming release - coreboot 4.12
================================
The 4.12 release is planned for April 2020
coreboot 4.12 was released on May 12th, 2020.
Update this document with changes that should be in the release
notes.
* Please use Markdown.
* See the past few release notes for the general format.
* The chip and board additions and removals will be updated right
before the release, so those do not need to be added.
Since 4.11 there were 2692 new commits by over 190 developers and of
these, 59 contributed for the first time, which is quite an amazing
increase.
Thank you to all developers who again helped made coreboot better
than ever, and a big welcome to our new contributors!
Maintainers
-----------
This release saw some activity on the MAINTAINERS file, showing more
persons, teams and companies declare publicly that they intend to
take care of mainboards and subsystems.
To all new maintainers, thanks a lot!
Documentation
-------------
Our documentation efforts in the code tree are picking up steam, with
some 70 commits in that general area. Everything from typo fixes to
documenting mainboard support or coreboot APIs.
There's still room to improve, but the contributions are getting more
and better.
Hardware support
----------------
The removals due to the announced deprecations as well as the
deduplication of boards into variants skew the stats a bit, so at
a top level view this is a rare coreboot release in that it removes
more boards (51) than it adds (49).
After accounting for the variant moves the numbers in favor of more
hardware supported than the previous version. Besides a whole lot
of Chrome OS devices (again), this release features a whole bunch
of retrofits for devices originally shipping with non-coreboot OEM
firmware, but also support for devices that come with coreboot right
out of the box.
For that, a shout out to System76, Protectli, Libretrend and the
Open Compute Project!
Cleanup
--------
We simplified the header that comes at the top of every file:
Instead of a lengthy reference to the license any given file
is under, or even the license text itself, we opted for simple
[SPDX](https://www.spdx.org) identifiers.
Since people also handled copyright lines differently, we now opt for
collecting authors in AUTHORS and let git history tell the whole story.
While at it, the content-free "This file is part of this-and-that
project" header was also dropped.
Besides that, there has also been more work to sort out the headers
we include across the tree to minimize the code impacting every
compilation unit.
Now that our board-variant mechanism matured, many boards that were
individual models so far were converted into variants, making it
easier to maintain families of devices.
Deprecations
------------
For the 4.12 release a few features on x86 became mandatory. These are
relocatable ramstage, postcar stage and C_ENVIRONMENT_BOOTBLOCK.
