Released 2025-07-22.

#10968

traps during legalization.
#10988
- The TE HTTP header can now be specified by guests.
#11002
- Winch on AArch64 should now pass all WebAssembly MVP tests. Note that it is
still not yet Tier 1 at this time, however.
#10829
#11013
#11031
#11051
- The x64 backend now has lowering rules for {add,sub,or,and} mem, imm
#11043
- Initial support for WASIp2 in the C API has started to land.
#11055
#11172
- Initial support for GC support in the component model has started to land
(note that it is not finished yet).
#10967
#11020
- The wasmtime-wasi-nn crate now has a feature to use a custom ONNX runtime.
#11060
- Cranelift now optimizes division-by-constant operations to no longer use
division.
#11129
- A native-tls backend has been added for the wasi-tls implementation.
#11064

... (and more)
- Wasmtime internally uses Pin for VM data structures to make the internal
implementations more sound to use. This has no effect on the public API of
Wasmtime.
#10934
#10937
#10943
#10959
#11042
- Fused adapters between components now transfer the enum component model type
more efficiently.
#10939
- Filenames of --emit-clif now match the symbol names found in *.cwasm
artifacts and include the function name as well.
#10947
#11040
- Wasmtime-internal crates are now all named wasmtime-internal-* to even
further discourage their use.
#10963
- Codegen of conditional traps with float compares has been improved.
#10966
- More patterns are now optimized in ISLE mid-end rules.
#10978
#10979
#11173
- Winch's support for constants/scratch registers has been improved internally.
#10986
#10998
- The C API artifacts on Windows are now produced with Clang instead of
cl.exe.
#10890
- WebAssembly operand types are now taken into account during translation to
optimize codegen better in the face of subtyping.
#11030
- The behavior of blocking-write-and-flush has been updated during flushing
when closed is found.
#11018
- WASI WITs have been updated to 0.2.6.
#11049
- OpenVINO has been updated to v2025.1.
#11054
- The size of the wasmtime.addrmap section in *.cwasm artifacts has been
shrunk slightly.
#11126
- Authorities in wasmtime-wasi-http can now contain the : character.
#11145
- Wasmtime now requires Rust 1.86 to compile.
#11142
- Wasmtime's DRC collector has been optimized and has a new more efficient means
of managing the set of over-approximated roots on the stack.
#11144
#11148
#11167
#11168
#11169
#11175
- The ComponentType trait in Wasmtime now requires the Send and Sync
bounds for all implementors.
#11160
- The V128 type is now usable on platforms other than aarch64 and x86_64.
#11165
- Wasmtime's policy on unsafe code and guidelines has been added.
#11177
- The std crate will no longer implicitly be used on cfg(unix) and
cfg(windows) targets when the std Cargo feature is disabled. This means
that these platforms now require std to be enabled to use the
platform-specific implementation of linear memory, for example.
#11152
Fixed
- A panic when optimizing icmp with vectors has been fixed.
#10948
- A panic when lowering scalar_to_vector with i16x8 types has been fixed.
#10949
- The vector state register is now considered clobbered by calls on riscv64 to
ensure it's updated across calls.
#11048
- An instance of gdb crashing on DWARF emitted by Wasmtime has been fixed.
#11077
- Fix a panic in the host caused by preview1 guests using fd_renumber.
CVE-2025-53901.
- Fix a panic in the preview1 adapter caused by guests using fd_renumber.
