A git-buildpackage(1)-style Debian package can be found at

This being the first release, there is no changelog;
the upstream homepage is at https://google.github.io/snappy/
(but really it's actually https://github.com/google/snappy).
The Snappy compression algorithm aims for very high speeds
and reasonable compression, suitable for real-time RPC scenarios,
but is also used by, i.a., Firefox to compress parts of the profile.
This package provides snappy(1) and unsnappy(1),
which handle Snappy compression and decompression with and without framing.

The high-lights of this release include:
1. snappy < /dev/tty on systems with loose lseek(2) semantics fixed
3. loong64 CRCC-accelerated CRC32C [not measured on hardware :/]
4. arm64 CRC32C-accelerated CRC32C [246=E2=86=925016MiB/s on MT8173's Corte=
x-A72]
5. soft CRC32Cs computed in parallel when compressing -f [130=E2=86=92199Mi=
B/s on E6400]
