I'm one of the upstream maintainers of zstd. If you have any questions, please feel free to either open an issue on the issue board [1] or email me or Yann Collet (CCed). The format has been stable since version 0.8.1, which was released on August 18th 2016. We have an RFC draft describing the compression format in progress [2], so we are completely committed to keeping the format stable. Long-term data storage is as much a priority for us as real-time data streaming. IMO one of the strengths of Zstandard is the ability to maintain the same fast decompression speed at every compression level. That allows both real-time streaming and long-term storage to use the same format.
