traps during legalization.

#11002

#11051
The x64 backend now has lowering rules for {add,sub,or,and} mem, imm
#11043

#11055
#11172

(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

division.
#11129

... (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 ofcl.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) andcfg(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
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.
