### Added
* Initial support for shared memories and the `threads` WebAssembly proposal
has been added. Note that this feature is still experimental and not ready
for production use yet.
[#4187](https://github.com/bytecodealliance/wasmtime/pull/4187)
* A new `Linker::define_unknown_imports_as_traps` method and
`--trap-unknown-imports` CLI flag have been added to conveniently support
running modules with imports that aren't dynamically called at runtime.
[#4312](https://github.com/bytecodealliance/wasmtime/pull/4312)
* The VTune profiling strategy can now be selected through the C API.

* Parallel compilation of WebAssembly modules is now enabled in the C API by
default.
[#4270](https://github.com/bytecodealliance/wasmtime/pull/4270)
* Implicit Cargo features of the `wasmtime` introduced through `optional`
dependencies may have been removed since namespaced features are now used.
It's recommended to only used the set of named `[features]` for Wasmtime.

[#4333](https://github.com/bytecodealliance/wasmtime/pull/4333)
* Lowering bugs for the `i8x16.swizzle` and `select`-with-`v128`-inputs
instructions were fixed for the x86\_64 code generator. Note that aarch64 and
s390x are unaffected.
[#4334](https://github.com/bytecodealliance/wasmtime/pull/4334)
* A bug in the 8-bit lowering of integer division on x86-64 was fixed in
Cranelift that could cause a register allocator panic due to an undefined
value in a register. (The divide instruction does not take a register `rdx`
as a source when 8 bits but the metadata incorrectly claimed it did.) No
impact on Wasm/Wasmtime users, and impact on direct Cranelift embedders
limited to compilation panics.
