NASM 3.0 released a few weeks back with the headline functionality being support for APX and AVX10 instruction sets. Plus new pre-processor functions including %b2hs(), %chr(), %depend(), %find(), %findi(), %hs2b(), %null(), %ord(), %pathsearch(), and %realpath(). There are also some new preprocessor directives, various fixes, documentation updates, and other minor changes but arguably most notable with this big release is the APX and AVX10 support.
NASM 3.01 released a week later with a new obj2 version of the obj output format for use on OS/2, new %selbits() preprocessor function, and other minor additions.
