 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.
