Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning. Additionally we have an Internal section for changes that are of interest to developers.

[0.13.2] - 2022-09-20

Note: This is going to be the last release with the legacy wasmi engine. Future releases are going to use the new Wasm execution engines that are currently in development. We may consider to publish the legacy wasmi engine as wasmi-legacy crate.

Fixed

[0.13.1] - 2022-09-20

Note: Yanked because of missing wasmi_core bump.

[0.13.0] - 2022-07-25

Note: This is going to be the last release with the legacy wasmi engine. Future releases are going to use the new Wasm execution engines that are currently in development. We may consider to publish the legacy wasmi engine as wasmi-legacy crate.

Changed

  • Update dependency: wasmi-validation v0.4.2 -> v0.5.0

[0.12.0] - 2022-07-24

Changed

  • wasmi now depends on the wasmi_core crate.
  • Deprecated RuntimeValue::decode_{f32,f64} methods.
    • Reason: These methods expose details about the F32 and F64 types. The RuntimeValue type provides from_bits methods for similar purposes.
    • Replacement: Replace those deprecated methods with F{32,64}::from_bits().into() respectively.
  • Refactor traps in wasmi: PR
    • This change also renames TrapKind to TrapCode.
    • The wasmi crate now properly reuses the TrapCode definitions from the wasmi_core crate.
  • Updated dependency:
    • parity-wasm v0.42 -> v0.45
    • memory_units v0.3.0 -> v0.4.0

Internal

  • Rename RuntimeValue to Value internally.
  • Now uses wat crate dependency instead of wabt for reading .wat files in tests.
  • Updated dev-dependencies:
    • assert_matches: v1.1 -> v1.5
    • rand 0.4.2 -> 0.8.2
  • Fix some clippy warnings.

[0.11.0] - 2022-01-06

Fixed

  • Make wasmi traps more conformant with the Wasm specification. (wasmi-labs#300)
  • Fixed a bug in {f32, f64}_copysign implementations. (wasmi-labs#293)
  • Fixed a bug in {f32, f64}_{min, max} implementations. (wasmi-labs#295)

Changed

  • Optimized Wasm to host calls. (wasmi-labs#291)
    • In some artificial benchmarks we saw improvements of up to 42%!
  • Introduce a more efficient LittleEndianConvert trait. (wasmi-labs#290)

Internal

  • Refactor and clean up benchmarking code and added more benchmarks.
  • Apply some clippy suggestions with respect ot #[must_use]. (wasmi-labs#288)
  • Improve Rust code formatting of imports.
  • Improve debug impl of ValueStack so that only the live parts are printed.

[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.
  • Bumped wasmi-validation from version 0.3.1 to 0.4.0.
