-Upcoming release - coreboot 4.9
+coreboot 4.9 release notes
 ==========================
 
-The 4.9 release is planned for November 2018
+The 4.9 release covers commit 532b8d5f25 to commit 7f520c8fe6
+There is a pgp signed 4.9 tag in the git repository, and a branch will
+be created as needed.
 
-Update this document with changes that should be in the release
-notes.
-* Please use Markdown.
-* See the [4.7](coreboot-4.7-relnotes.md) and [4.8](coreboot-4.8.1-relnotes.md)
- 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.
+In the little more than 7 months since 4.8.1 we had 175 authors commit
+2610 changes to master. The changes were, for the most part, all over
+the place, touching every part of the repository: chipsets, mainboards,
+tools, build system, documentation.
 
+In that time we also had 70 authors made their first commit to coreboot:
+Welcome and to many more!
 
+Finally, 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.
+
+Clean up
+--------
+If there's any topic to give to this release, "clean up" might be the
+most appropriate: There was lots of effort to bring the codebase into
+compliance with our coding style, to remove old idioms that we'd like
+to retire like the overloaded `device_t` data type, and to let features
+percolate through the entire tree to bring more uniformity to its parts.
+
+For example, during the coreboot 4.4 cycle, coreboot gained the notion
+of mainboard variants to avoid duplication of code in rather similar
+mainboards.
+
+Back then, this feature was developed and used mostly for the benefit
+of Chrome OS devices, but more recently the code for various Lenovo
+Thinkpads was deduplicated in the same way.
+
+Another part of cleaning up our tree is improving our tools that help
+developers follow coding style and avoid mistakes, as well as the
+infrastructure we have for automated build tests and we've seen quite
+some activity in that space as well.
+
+Documentation
+-------------
+Since the last release we also moved the documentation into the
+repository. No need for a special wiki account to edit the documentation,
+and by colocating sources and documentation, it's easier to keep the
+latter in sync with the code, too.
+
+This effort is still under way, which is why we still host the old wiki (now
+read-only) in parallel to the [new documentation
+site](https://doc.coreboot.org) that is rendered from coreboot.git's
+Documentation/ directory.
+
+Blobs handling
+--------------
+Another big change is in our blobs handling: Given that Intel now
+provides a reasonably licensed repository with FSP binaries, we were
+able to mirror it to coreboot.org and integrate it in the build system.
+This makes it easier to have working images out of the box for devices
+that depend on Intel's proprietary init code.
+
+As usual the blobs aren't part of the coreboot tree and only downloaded
+with the `USE_BLOBS` options.
+
+Deprecations
+------------
+One of the first changes to coreboot after the 4.8 release was to remove
+boards that didn't support certain new features and were apparently
+unmaintained, as discussed in the release notes of coreboot 4.6.
+
+We didn't follow up on all plans made back then to deprecate boards more
+aggressively: The board status reporting mechanism is still rather raw
+and therefore places quite a burden on otherwise sympathetic contributors
+of build results.
+
+Also, there will be no deprecations after 4.10: Due to its slipping
+schedule, coreboot 4.9 is released rather late, and as a result 4.10
+will only see about 4 months of development. We considered that a rather
+short timeframe in which to bring old boards up to new standards, and
+so the next deprecation cycle may be announced with 4.10 to occur after
+4.11 is released, in late 2019.
 
 General changes
 ---------------
-
 * Various code cleanups
- * Removed `device_t` in favor of `struct device*` in ramstage code
- * Improve adherence to coding style
+  * Removed `device_t` in favor of `struct device*` in ramstage code
+  * Removed unnecessary include directives
+  * Improved adherence to coding style
+  * Deduplicated boards by using the variants mechanism
 * Expand use of the postcar stage
 * Add bootblock compression capability: on systems that copy the bootblock
-  from very slow flash to ERAM, allow adding a stub that decompresses the
-  bootblock into ERAM to minimize the amount of flash reads
+  from very slow flash to SRAM, allow adding a stub that decompresses the
+  bootblock into SRAM to minimize the amount of flash reads
 * Rename the POWER8 architecture port to PPC64 to reflect that it isn't limited
   to POWER8
+* Added support for booting FIT (uImage) payloads on arm64
+* Added SPI flash write protection API
+  * Implemented on Winbond
+* Implemented TCPA log for measured boot
+* Implemented GDB support for arm64 architecture in libpayload
