Context: Zstandard is a compression algorithm invented by Yann Collet, with the goal to exceed zlib's compression performance along every dimension (those being compression ratio, compression speed, and decompression speed). Although that bar was cleared long ago, we've continued to work to improve Zstd, and with this release, we've made Zstd just that little bit more hardened/better/faster/stronger.
Zstd is awesome. I’d love to see desktop archive software include these algorithms. There’s a fork of 7-Zip called 7-Zip ZS that includes zstd and some other algorithms and I found they performed really well for my use case, proving fairly comparable compression to alternatives at a much, much faster speed. Handy for when you want to archive a massive directory of files or a small number of really large files.
