xxHash v0.8.0 - Stable XXH3
Stable XXH3
After more than a year in the making, XXH3 has finally reached stable status, for both its 64-bit and 128-bit variants.
While the code itself was in good enough shape for production use, the generated values could still change between versions. This limited XXH3 to local sessions only.
From now on, output values produced by XXH3 for a given input and parameter set will remain identical across systems and across future versions. It makes it possible to store these values for later comparison, or to exchange them across network connections.
BSD-style checksums
Official stabilization being the main goal of this release, there are only minimal additional changes.
A notable one though is the ability for xxhsum CLI to produce and check BSD-style checksum lines, using command --tag.
One advantage of --tag format is that it explicitly specifies the algorithm and format used to represent the checksum. For example, it explicitly mentions if a checksum value follows the canonical format (XXH32) or the alternative little-endian format (XXH32_LE).
Generating BSD-style checksum lines was actually already possible, but as the CLI was unable to --check them, it remained a hidden option.
This situation changes with v0.8.0, thanks to a patch by @WayneD which makes it possible to --check BSD-style checksum lines.
