  #7854

• Add the WasiP1Ctx to ease the use of wasmtime-wasi in place of wasi-common
  #8053

• The Winch compiler backend is now feature-complete for x64. Note that minor
  issues and fuzz bugs are still being addressed, but now's a good time to test
  if you're interested.
  #7894
  #7909
  #7927
  #7932
  #7949
  #7974
  #8001

• The typed function references proposal to WebAssembly is now fully
  implemented.
  #7943

• The component::Linker type is now "semver aware" in that it enables loading
  components referring to past or future versions of interfaces so long as the
  types are compatible.
  #7994

• Wasmtime can now be built for "custom platforms" which is intended for
  bare-metal builds.
  #7995

• The wasmtime-wasi-nn crate now has a backend based on WinML.
  #7807

• The wasmtime CLI now has flags for configuring limits of the pooling
  allocator.
  #8027

Changed

• The wasmtime serve command no longer binds its port with SO_REUSEADDR
  meaning that if it is invoked twice only one will succeed.
  #7863

• The sampling-based profiler in Wasmtime now takes an explicit argument of
  the time delta between samples.
  #7873

• Many accessors for type information now require an &Engine argument to be
  specified in preparation for an implementation of wasm GC.
  #7892

• The host header is now forbidden in wasi-http.
  #7905

• Stronger type-checks are now performed for host-owned resources when
  interacting with the component model to help catch mistakes earlier.
  #7902

• Demangling Rust and C/C++ symbols in WebAssembly modules is now done by
  default in the C API.
  #7962

• Preview2-based APIs are now located at the root of the wasmtime_wasi crate
  instead of a submodule.
  #7933

• Components now reserve index 0 for handle tables to match the component model
  specification.
  #7661

• Support for externref has been moved behind a new gc Cargo feature. This
  will also gate support for wasm gc in the future.
  #7975

• Require the WASMTIME_WASI_CONFIG_PREOPEN_SOCKET_ALLOW environment variable
  to bet set to allow the use of wasi_config_preopen_socket via the c api, as
  it will be deprecated in 20.0.0.
  #8053

Fixed

• WIT interface names that are Rust keywords now correctly generate bindings.
  #7790

• PKRU state is now restored across await points.

  unary and binary operations, leading to miscompilations.
  #8005

  publication of the 18.0.0 release to not succeed.
  #7966

v18.0.0: Release Wasmtime 18.0.0 (#7958)

18.0.0

  ability to dynamically and fallibly upgrade it to an Engine.

  #7811

• The import and export types of a Component can now be inspected at runtime.

  module exports without using string lookups with Module::get_export_index.

• Owned resources represented with ResourceAny can now be passed as arguments
  to functions that require a borrow<T> parameter.
  #7783

• Generated structures from wasmtime::component::bindgen! for exported
  interfaces are now all renamed to Guest to avoid conflicting with WIT names.
  #7794

• Guest profiler output will now automatically demangle symbols.
  #7809

• The wasmtime crate now has a runtime Cargo feature which, if disabled,
  enables building Wasmtime with only the ability to compile WebAssembly
  modules. This enables compiling Wasmtime's compilation infrastructure, for
  example, to WebAssembly itself.
  #7766

• Support for the old wasi-common crate and the original implementation of
  "WASIp1" aka "preview1" is being deprecated in the wasmtime-wasi crate.
  Users should migrate to the wasmtime_wasi::preview2 implementation, which
  supports both WASIp1 and WASIp2, as in the next release the
  wasi-common-based reexports of wasmtime-wasi will be deleted.
  #7881

v17.0.1: Release Wasmtime 17.0.1 (#7890)

  invalid.
  #7859

• Fix an egraph rule bug that was allowing unconstrained recursion through the
  DFG to run away on large functions.
