 Upcoming release - coreboot 4.19
 ========================================================================
 
-The 4.19 release is planned for January 2023.
+The 4.19 release is planned for the 15th of January 2023.
+
+Since the last release, the coreboot project has merged almost 1500
+commits from over 150 authors.  Of those authors, more than 20 were
+first-time committers to the coreboot project.
+
+As always, we are very grateful to all of the contributors for helping
+to keep the project going.  The coreboot project is different from many
+open source projects in that we need to keep constantly updating the
+codebase to stay relevant with the latest processors and technologies.
+It takes constant effort to just stay afloat, let alone improve the
+codebase.  Thank you very much to everyone who has contributed, both
+in this release and in previous times.

+Significant or interesting changes
+----------------------------------
+
+### Show all Kconfig options in saved config file, compress it
+
+The coreboot build system automatically adds a 'config' file to CBFS
+that lists the exact Kconfig configuration that the image was built
+with. This is useful to reproduce a build after the fact or to check
+whether support for a specific feature is enabled in the image.
+
+This file has been generated using the 'savedefconfig' Kconfig command,
+which generates the minimal .config file that is needed to produce the
+required config in a coreboot build. This is fine for reproduction, but
+bad when you want to check if a certain config was enabled, since many
+options get enabled by default or pulled in through another option's
+'select' statement and thus don't show up in the defconfig.
 
-### Add significant changes here
+Instead coreboot now includes a larger .config instead. In order to save
+some space, all of the comments disabling options are removed from the
+file, except for those included in the defconfig.
 
+We can also LZMA compress the file since it is never read by firmware
+itself and only intended for later re-extraction via cbfstool, which
+always has LZMA support included.
