### 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. |

* 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. |
