v25.0.1: Release Wasmtime 25.0.1 (#9306)

25.0.1

Released 2024-09-24.

Added

• The wasmtime CLI's -Wmax-wasm-stack option now automatically configures
  the async stack size as well. A new -Wasync-stack-size option was
  additionally added to configure it too.
  #9302

v25.0.0: Release Wasmtime 25.0.0 (#9289)

25.0.0

Released 2024-09-20.

Added

• The WinML backend of wasmtime-wasi-nn now supports FP16 and I64.
  #8964

• Pooling allocator configuration options for table elements and core instance
  size can now be changed on the CLI.
  #9138

• Wasmtime now supports the extended-const WebAssembly proposal.
  #9141

• The wasmtime crate embedding API now has ArrayRef for allocating wasm GC
  arrays.
  #9145

• Cranelift now has a stack_switch CLIF instruction to be used with the
  WebAssembly stack switching proposal.
  #9078

• There are now more constructors available on bindgen!-generated structures
  for component exports now which use instantiated components rather than
  pre-instantiated components.
  #9177

Changed

• The host bindgen macro now accepts a new verbose_tracing option, which will
  trace the value of list arguments. The new behavior of the tracing option
  is that it does not print list values without verbose_tracing also being
  present.
  #9262

• Wasmtime's support for WASI is now listed with the 0.2.1 version instead of
  0.2.0. This is expected to not cause fallout or breakage, but please open an
  issue if you see any problems.
  #9063

• Work continues on Winch's AArch64 backend.
  #9114
  #9092
  #9171

• Component model resource methods can now be generated as async and will do
  so by default if async is enabled for all functions.
  #9091

• Work has continued on Wasmtime's interpreter backend, Pulley.
  #9089

• The internal implementation of input-stream and output-stream for
  filesystems in wasmtime-wasi have been refactored to directly implement
  the corresponding host traits. This additionally helps cleanup the internal
  organization of host-side resources in wasmtime-wasi.
  #9129

• Wasmtime now uses the new "user" stack maps in Cranelift rather than the old
  regalloc-based stack maps for GC references.
  #9082

• Wasmtime's handling of WebAssembly features now works slightly differently
  from before to provide better error messages and fewer panics on unsupported
  WebAssembly features depending on compiler and target selection. Additionally
  the reference-types WebAssembly proposal is always on-by-default regardless of
  crate features.
  #9158
  #9162

• The wasmtime CLI will now use the async version of I/O where possible to
  properly support -Wtimeout and timing out instances blocked in I/O.
  #9184

Fixed

• Use tracing::Instrument in generated bindings when tracing and async are
  enabled, ensuring that spans aren't present in traces from unrelated async
  tasks.
  #9217
  #9263

• Completed support for the CallHook API when using the component model.
  #9196

• The compile time for a component model enum type with many cases should be
  much improved now.
  #9122

• Some minor bugfixes have been made for when Wasmtime is working with split
  DWARF in WebAssembly files.
  #9109
  #9132
  #9134
  #9139
  #9151

• An issue with bounds checks and dynamic checks has been fixed in Winch to
  ensure bounds checks are correctly implemented.
  #9156

• Support for Winch on AArch64 continued to improve.
  #8921
  #9018
  #9033
  #9051

• An initial implementation of the wasi-runtime-config proposal was added to
  Wasmtime.
  #8950
  #8970
  #8981

• Initial support for f16 and f128 in Cranelift continued to improve.
  #8893
  #9045

• More types in wasmtime-wasi-http implement the Debug trait.
  #8979

• The wasmtime explore subcommand now supports exploring CLIF too.
  #8972

• Support for SIMD in Winch has begun, but it is not complete yet.
  #8990
  #9006

  #9022

• The s390x backend now fully supports tail calls.
  #9052

Changed

  flags. For more information about this transition see
  WebAssembly/component-model#370.
  #8882

• Multiple returns for functions in the component model are now gated by default
  and are planned to be removed.
  #8965

  the TCP stream is closed or shut down.
  #8968
  #9055

• Cranelift will now perform constant propagation on some floating-point
  operations.
  #8954

• Wasmtime and Cranelift now require at least Rust 1.78.0 to compile.
  #9010

• The wasmtime::Val type now implements the Copy trait.
  #9024

• Wasmtime's wasi-nn implementation has been updated to track the upstream
  specification.
  #9056

• Names provided to trappable_imports in bindgen! are now validated to be
  used.
  #9057

• Support for multi-package *.wit files now requires a package ...; header
  at the top of the file.

  directory for header files with configured versions of header files.
  #9102
• Wasmtime no longer requires linking with libm in Linux builds, which
  fixes linking against musl in some cases.
