+coreboot 4.10 release notes
 ===========================
 
-The 4.10 release is planned for April/May 2019
+The 4.10 release covers commit a2faaa9a2 to commit ae317695e3
+There is a pgp signed 4.10 tag in the git repository, and a branch will
+be created as needed.

-Significant changes
+Between the releases the tree grew by about 11000 lines of code plus

+Again, a big Thank You to all contributors who helped shape the coreboot
+project, community and code with their effort, no matter if through
+development, review, testing, documentation or by helping people asking
+questions on our venues like IRC or our mailing list.
+
+What's New
+----------
+
+Most of the changes were to mainboards, and on the chipset side, lots
+of activity concentrated on x86. However compared to previous releases
+activity (and therefore interest, probably) increased in vboot and in
+non-x86 architectures. However it's harder this time to give this release
+a single topic like the last: This release accumulates some of everything.
+
+Clean Up
+--------
+As usual, there was a lot of cleaning up going on, and there notably,
+a good chunk of this year's Google Summer of Code project to clean out
+the issues reported by Coverity Scan is already in.
+
+The only larger scale change that was registered in the pre-release
+notes was also about cleaning up the tree:

 That data type is now gone.

+Release Notes maintenance
+-------------------------
+Speaking of pre-release notes: After 4.10 we'll start a document for
+4.11 in the git repository. Feel free to add notable achievements there
+so we remember to give them a shout out in the next release's notes.
+
+Known Issues
+------------
+Sadly, Google Cyan is broken in this release. It doesn't work with the
+"C environment" bootblock (as compared to the old romcc type bootblock)
+which is now the default. Sadly it doesn't help to simply revert that
+change because doing so breaks other boards.
+
+If you want to use Google Cyan with the release (or if
+you're tracking the master branch), please keep an eye on
+https://review.coreboot.org/c/coreboot/+/34304 where a solution for this
+issue is sought.
+
+Deprecations
+------------
+As announced in the 4.9 release notes, there are no deprecations after 4.10.
+While 4.10 is also released late and we target a 4.11 release in October we
+nonetheless want to announce deprecations this time: These are under
+discussion since January, people are working on mitigations for about as long
+and so it should be possible to resolve the outstanding issues by the end of
+October.
+
+Specifically, we want to require code to work with the following Kconfig
+options so we can remove the options and the code they disable:
+
+* C\_ENVIRONMENT\_BOOTBLOCK
+* NO\_CAR\_GLOBAL\_MIGRATION
+
+These only affect x86. If your platform only works without them, please
+look into fixing that.
