[PATCH] D28746: Mention ThinLTO with PGO in ReleaseNotes 4.0

[Mehdi AMINI via Phabricator via cfe-commits]

Oh I didn't notice that we were in the clang Release Notes, actually I've only updated the LLVM ones in the past.

So yes, I think this should be in LLVM as well, I don't know if it should differ in some way?
