They don't (and won't) exist. We just went to version 5 wholesale to
make it easier to distinguish between the new and old file format -- in
the future new features etc. won't be announced by versions but by TLVs
in the file format (see the code that loads the ucode file from disk)
unless the firmware is completely incompatible.
