v1.7.0

Compare Source

version 1.7.0

Changes since 1.6.1:

• The C implementation has gained multithreading support, based on
  Intel's oneTBB library. This works similarly to the Rayon-based
  multithreading used in the Rust implementation. See c/README.md for
  details. Contributed by @​silvanshade (#​445).
• The Rust implementation has gained a WASM SIMD backend, gated by the
  wasm32_simd Cargo feature. Under Wasmtime on my laptop, this is a 6x
  performance improvement for large inputs. This backend is currently
  Rust-only. Contributed by @​monoid (#​341).
• Fixed cross-compilation builds targeting Windows with cargo-xwin.
  Contributed by @​Sporif and @​toothbrush7777777 (#​230).
• Added b3sum --tag, which changes the output format. This is for
  compatibility with GNU checksum tools (which use the same flag) and
  BSD checksum tools (which use the output format this flag turns on).
  Contributed by @​leahneukirchen (#​453) and @​dbohdan (#​430).
