As usual, the full release notes are found on Github: https://github.com/facebook/zstd/releases/tag/v1.4.5 Notable changes include: * Improved decompress performance on amd64 and arm (5-10% and 15-50%, respectively). * '--patch-from' zstd(1) CLI option, which provides something like a very fast version of bspatch(1) with slightly worse compression. See release notes. In this update, I dropped the 3-year old -O0 workaround for an LLVM ARM bug; the bug was fixed in LLVM SVN in 2017, but we didn't remove this workaround from our tree until now. MFC after: I won't, but feel free Relnotes: yes
