sorry, I might be just blind. But there don't seem to be release notes
for the version from June:

  [icon at bob FSP]$ git checkout KabylakeFsp0001
  HEAD is now at d88078a... initial Kabylake FSP check-in.
  [icon at bob FSP]$ find . -iname *release*
  [icon at bob FSP]$ git grep -i release
  KabylakeFspBinPkg/Fsp.bsf:        Help "Size of SMRAM memory reserved.
0x400000 for Release build and 0x1000000 for Debug build"
  KabylakeFspBinPkg/Include/FspmUpd.h:  Size of SMRAM memory reserved.
0x400000 for Release build and 0x1000000 for Debug build
  KabylakeFspBinPkg/SampleCode/Vbt/Vbt.bsf:$RelStage
            1 byte      ; Release status
  [icon at bob FSP]$

The release notes of the Gold release mention it, though. But, earlier
versions often listed only one variant while they supported all. Doesn't
matter any more, I guess. If they force people to reverse engineer their
stuff, that's ok for me (I'm pretty sure now that this is less effort,
than ensuring their undocumented blobs work).

Now this is what I call a Google Support Package.
