v1.1.2
Improved : faster decompression speed at ultra compression settings and in 32-bits mode
cli : new : preserve file attributes, by Przemyslaw Skibinski
cli : fixed : status displays total amount decoded when stream/file consists of multiple appended frames (like pzstd)
cli : new : gzstd, experimental version able to decode .gz files, by Przemyslaw Skibinski
cli : new : preserve file attributes
cli : new : added zstdless and zstdgrep tools
cli : fixed : status displays total amount decoded, even for file consisting of multiple frames (like pzstd)
cli : fixed : zstdcat
API : changed : zbuff prototypes now generate deprecation warnings
API : changed : streaming decompression implicit reset on starting new frame
Changed : reduced stack memory use
v1.1.1
New : command -M#, --memory=, --memlimit=, --memlimit-decompress= to limit allowed memory consumption
