This should mention the new API that's exposed in public headers. In 
this case it's the new FF_PROFILE_* defines.

Also, could you split this in three patches? One for DTS, one for EAC3 
and one for TrueHD? The order is not important, and the version bump and 
the APIChanges entry would then be added in the last patch.
Also, remove the mention about ffprobe since you're not touching it at 
all. The new profiles will be reported by any tool that prints them, 
like ffmpeg, not just ffprobe.
