+Upcoming release - coreboot 24.02
+========================================================================
+
+The 24.02 release is scheduled for Mid February, 2024
+
+
+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.
+* Note that all changes before the release are done are marked upcoming.
+  A final version of the notes are done after the release.
+
+### Release number format update
+
+The previous release was the last to use the incrementing 4.xx release
+name scheme. For this and future releases, coreboot has switched to a
+Year.Month.Sub-version naming scheme. As such, the next release,
+scheduled for May of 2024 will be numbered 24.05, with the sub-version
+of 00 implied. If we need to do a fix or incremental release, we’ll
+append the values .01, .02 and so on to the initial release value.
