Thanks. Is it possible that the NEWS file could be corrected for the 5.2.0 release as well? I suspect this should say "Multi-threaded compression" (as opposed to decompression). http://git.tukaani.org/?p=xz.git;a=blob;f=NEWS;hb=HEAD 69 - Multi-threaded decompression can be enabled with the 70 --threads (-T) option. -Andy
