v0.40.0 - 2024-11-28

This release focuses on compile time improvements for Wasmi,
significantly reducing the time it takes to compile Wasmi and
decrease its compiled artifact size.

Added

• Added optimization for load and store lowering. #1303
  • This reduces the total number of Wasmi instructions.
• Added prefix-symbols crate feature to wasmi_c_api_impl crate. #1315
  • This allows to prefix all exported symbols with wasmi_ in order to
    avoid duplicate symbols when linking multiple Wasm runtimes implementing
    the Wasm C-API.

Fixed

• C-API
  • Fix a minor compilation issue. #1296
  • Fix the name of wasmi_config_compilation_mode_set #1298
• Conditionally forward the string-interner/std crate feature. #1304
• Fix Wasmtime fuzzer oracle config usage. #1314

Changed

• Bumped minimum supported Rust version from v1.79 -> v1.80. #1318
• Replace the wasmparser-nostd fork with upstream wasmparser. #1141
  • This allows Wasmi to implement new Wasm proposals.
  • Unfortunately this update also regresses Wasmi translation performance
    by roughly 5-15% depending on the exact Wasm blob and translation mode.
• Update the string-interner and hashbrown dependencies. #1305

Internal

• Update the wast dependency for Wasmi's Wast runner. #1306
• Update wasm-tools dependencies to v0.221. #1318
