zstd - Zstandard - Fast real-time compression algorithm

Zstd, short for Zstandard, is a lossless compression algorithm. Speed vs. compression trade-off is configurable in small increments. Decompression speed is preserved and remains roughly the same at all settings, a property shared by most LZ compression algorithms, such as zlib or lzma.

At roughly the same ratio, zstd (v1.4.0) achieves ~870% faster compression than gzip. For roughly the same time, zstd achives a ~12% better ratio than gzip. LZMA outperforms zstd by ~10% faster compression for same ratio, or ~1–4% size reduction for same time.

  • Bump Standards-Version to 4.4.1, changes noted above
  • Update symbols file for libzstd1
  • Call dh_makeshlibs with -V 'libzstd1 (>= 1.4.4)', since this version introduced new public symbols
  • Add an entry in debian/source/lintian-overrides to prevent libzstd1's Section entry from triggering binary-control-field-duplicates-source, since this field is necessary for the build
