Bumps wasmtime from 39.0.1 to 41.0.1.

Release notes

Sourced from wasmtime's releases.

v41.0.1

41.0.1

Released 2026-01-26.

Fixed

  • Fixed a bug in lowering of f64.copysign on x86-64 whereby when combined with an f64.load, the resulting machine code could read 16 bytes rather than 8 bytes. This could result in a segfault when Wasmtime is configured without signals-based traps.

v41.0.0

41.0.0

Released 2026-01-20.

Added

  • Support for {Future,Stream}Any in the component model has improved. #12142

  • Wasmtime has initial support for breakpoints and single-stepping with the debug feature for guest programs. #12133

  • Wasmtime has begun adding a new Error type which is similar to anyhow::Error but supports gracefully handling OOM. Wasmtime still uses anyhow::Error but this will change in the future to wasmtime::Error which will be a distinct type. #12163

  • An initial top-level crate for async-debugging guest programs has been added. #12183

Changed

  • Cranelift now optimizes redundant select + icmp instructions. #12135

  • Synchronous component model functions can no longer block before returning. This implements a change in the upstream specification to the upcoming async support in the component model which places stricter restrictions on non-async functions and their ability to perform blocking operations. #12043

  • Frame iteration in debug mode now visits all activations which enables seeing all frames from recursive wasm calls. #12176

... (truncated)
