Scarica Wasmtime 43.0.0 per Windows

Added
- Wasmtime now supports the WASIp3 snapshot 0.3.0-rc-2026-03-15. #12557
- The number of frames captured in backtrace collection can now be configured. #12542
- Wasmtime now supports fine-grained operator cost configuration for when fuel is enabled. #12541
- Configuring the gc_support option is now possible through the C API. #12630
- Configuring the concurrency_support option is now possible through the C API. #12703
- Debugging-related APIs have been added to access all modules and instances on a store. #12637
- All store entities now expose a "unique ID" for debugging purposes. #12645
- Cranelift's x64 backend now supports the cls instruction for all integer types. #12644
Changed
- Internal refactoring and support necessary for handling OOM gracefully throughout the runtime is proceeding apace. New APIs such as FuncType::try_new are available in addition to many internal changes. #12530 #12537 (... and many more ...)
- Wasmtime's representation of stack frames in the debugging API no longer borrows the store itself and is instead represented as a handle. #12566
- Wasmtime now unconditionally sets SO_REUSEADDR for guest-bound sockets. #12597
- Cranelift now supports more VRegs which means effectively that larger functions will be compilable by default rather than returning a "function too large" error. #12611
- WASIp3 implementations now limit returned memory by default for randomness and HTTP headers. #12745 #12761
Fixed
- Running wasmtime wizer over components with modules that contain an _initialize function no longer removes the function to preserve the validity of the component. #12540
- Borrow state for host async tasks is now handled more correctly throughout Wasmtime, especially in the face of cancellation. #12550
- Bindings generation now accounts for the fact that future and stream are not cloneable types. #12155
- The impementation of UDP in WASIp2 has had some wakeup-related bugs fixed. #12629
- Cancellation of host subtasks for component-model-async has been improved and works more reliably. #12640
- Subtask management for component-model-async now no longer reparents which fixes a number spec-related divergences. #12570
- Converting a wasmtime::Error into anyhow::Error and using downcast has been fixed. #12689
- Async stream/future read/write cancellation has had some corner cases fixed. #12704
- Cranelift's timing infrastructure is now more robust in the face of buggy system clocks. #12709
- The currently running guest task has been corrected in a number of cases related to component-model-async and cooperative threading. #12718 #12735 #12736 #12737
- An issue of lost wakeups with the WASIp3 stdin implementation has been fixed. #12745
