Wasmtime 48.0.0 ڈاؤن لوڈ

Added
- Wasmtime has an initial implementation of the component model fixed-length-lists feature. #12315
- Wasmtime's reflection of component imports/exports now exposes external-id information. #13874
- Cranelift's alias analysis pass now eliminates dead stores. #13806 #13947
- Winch now supports the wasm SIMD proposal on AArch64. #13911 #13921 #13928 #13937 #13945 #13938 #13946 ...
- Cranelift now supports an AVX512-VNNI lowering for the dot-product wasm instruction and usdot on AArch64. #14006 #14054
- Wasmtime's bindgen! macro now has an include_component_type option to generate a COMPONENT_TYPE constant with the encoded type of the world being bound. #14013
- Wasmtime now supports configurable fuel costs for variable-length wasm opcodes. #13931
Changed
- Host-implemented traits in wasmtime-wasi-http are now the same across wasip2/wasip3 and no longer require separate implementations/structures. #13810 #13812 #13835
- Wasmtime will now use the process_madvise syscall on Linux where available which can improve the performance of the pooling allocator when the deallocation batch size is configured to larger than 1. #13830
- Synchronous cancellation of streams/futures/subtasks now traps if the waitable was already in a waitable set. #13708
- Winch is now flagged to be compatible with component-model-async. #13845
- Wasmtime's pooling allocator now uses more sharding to reduce lock contention. #13840
- Wasmtime now requires Rust 1.95.0 to build. #13853
- Cranelift now has a uniform maximum size across all backends on the bounds of a function's stack frame. #13783
- Wasmtime's LinkerInstance for components now supports being reopened to gradually add more items. #13908
- The wasmtime-wasi crate's default configuration now denies creation of TCP/UDP sockets by default. #13936
- Wasmtime now configures async task context fields on realloc calls to zero. #13949
- Work has continued on continuous verification of Cranelift's lowering rules on AArch64. #13935 #13929 #13998
- Codegen for loads on AArch64 has been optimized slightly to improve sharing common sub-expressions. #13766
- Work continues on implementing the stack-switching proposal. #11717 #13996 #14052
- Permissions for wasi-filesystem in the implementation of the wasmtime-wasi crate have been simplified to either read-write or read-only for a directory. #14010
Fixed
- A late-drop of host-defined stream producers/consumers has been fixed. #13891
- Call hooks are now invoked around async yields when dealing with concurrent execution. #13871
- Extreme filesystem timestamps no longer cause panics. #13894
- An erroneous trap was fixed where an async-delivered write-closed event was sent to a future. #13914
- An erroneous trap where Wasmtime internally used the wrong thread id has been fixed. #13926
- Cross-component instance streams are no longer erroneously flagged as being intra-instance. #14018
- A panic in the wasmtime CLI with non-utf8 environment variables has been fixed. #14017
