  • Fixed a bug in {f32, f64}_{min, max} implementations. (wasmi-labs#295)

    • In some artificial benchmarks we saw improvements of up to 42%!
  • Introduce a more efficient LittleEndianConvert trait. (wasmi-labs#290)

[0.10.0] - 2021-12-14

Added

Changed

  • The wasmi and wasmi-validation crates now both use Rust edition 2021.
  • The README now better teaches how to test and benchmark the crate.
  • Updated num-rational from version 0.2.2 -> 0.4.0.

Deprecated

  • Deprecated MemoryInstance::get method.
    • Users are recommended to use MemoryInstance::get_value or MemoryInstance::get_into methods instead.

Removed

  • Removed support for virtual memory on 32-bit platforms.
    • Note that the existing support was supposedly not more efficient than the Vec based fallback implementation anyways due to technical design.
  • Removed the core crate feature that previously has been required for no_std builds.
    • Now users only have to specify --no-default-features for a no_std build.

Internal

  • Fully deploy GitHub Actions CI and remove deprecated Travis based CI. Added CI jobs for:
    • Testing on Linux, MacOS and Windows
    • Checking docs and dead links in docs.
    • Audit crate dependencies for vulnerabilities.
    • Check Wasm builds.
    • File test coverage reports to codecov.io.

[0.9.1] - 2021-09-23

Changed

  • Added possibility to forward reduced_stack_buffers crate feature to parity-wasm crate.

Internal

  • Added a default rustfmt.toml configuration file.
  • Fixed some warnings associated to Rust edition 2021.
    • Note: The crate itself remains in Rust edition 2018.

[0.9.0] - 2021-05-27

Changed

  • Updated parity-wasm from verion 0.41 to 0.42.
