0x000b06a8 was updated to the same microcode revision as the other steppings (0x000b06a2, 0x0000b06a3) were, so it looks like a simple omission from the release notes. Still, it would be nice to know for sure whether this update was intended or not [for this release].

Yes, you are correct. The MCU was updated for 06-ba-08 and is missing from the releasenotes.md file.

Just to check, are you asking about 06-ba-08 because somebody has a processor with this CPUID or because it was included in the updated files? I went back and verified, 06-ba-08 is not yet a production product and so we don't need to support this family-model-stepping yet.

[stormi]

Just because it was included in the updated files.

This signature is an extended signature in a single microcode data file that covers sigs 0x000b06a2, 0x000b06a3 as well. It doesn't even make sense to not distribute it.

Also, now that I did a search for it, we've been distributing this one since 20240312 in Debian (and so does everyone else)... it is on our automated changelogs generated using iucode_tool.
