## 6.1.0 - 08/10/2025

This release adds:

* The dynamic linker which, paired with [wasixcc](https://github.com/wasix-org/wasixcc),
  can load DL modules at runtime
* New WASIX syscalls for reflection, dynamic function invocation and closure creation;
  this makes WASIX compatible with libffi
* Better support for the Exception Handling proposal in the LLVM backend
* The `--build-remote` flag for `wasmer deploy`, which lets you build packages in the
  cloud rather than locally
* And many more stability fixes and improvements.

A new major release, with a few breaking changes and the removal of many deprecated functions. Also, some methods previously available from on `Engine` has been moved to the `NativeEngineExt` trait.
Deserialize has changed, with the default version using artifact layout validation. The old function has been renamed to `_unchecked` variant. The speed impact is usually negligeable , but the old function are still present if needed

## 3.2.0 - 18/04/2023

A lot of new features since last stable version:
RISCV Support, new Runners (WCGI), API convergence for JS/SYS, and WASI eXtended.

 * RISCV support, on both Cranelift and LLVM Compiler.
 * New Runners, with WCGI as a new one
 * Most WAPM command are now available on the wasmer CLI directly
 * Using Wasmer on `sys` or `js` backend is more transparent now, with now support for running wasmer on`JavaScriptCore`

 * The WASI implementation has undergone a major refactoring, and will continue evolve significantly over the coming months.
    - The old `wasmer_wasi` crate was deprecated.

    - To continue using WASI, please switch to the new `wasmer_wasix` crate, which follows a different versioning scheme than the main Wasmer releases.
    Major changes:
    - An async runtime is now required. The runtime is pluggable, but only tokio is officially supported at the moment.
    - The virtual file system layer was renamed from `wasmer-vfs` to `virtual-fs`, and now is built around an async interface that builds on top of `tokio::{AsyncRead/Write}`

    This refactor will unlock many exciting new features that will be announced soon!
    Just be aware that you will have to expect some instability and frequent releases with potential breaking changes until our new implementation settles. down.

## 1.0.1 - 2021-01-12

This release includes a breaking change in the API (changing the trait `enumset::EnumsetType` to `wasmer_enumset::EnumSetType` and changing `enumset::EnumSet` in signatures to `wasmer_enumset::EnumSet` to work around a breaking change introduced by `syn`) but is being released as a minor version because `1.0.0` is also in a broken state due to a breaking change introduced by `syn` which affects `enumset` and thus `wasmer`.

This change is unlikely to affect any users of `wasmer`, but if it does please change uses of the `enumset` crate to the `wasmer_enumset` crate where possible.

### Added
- [#2010](https://github.com/wasmerio/wasmer/pull/2010) A new, experimental, minified build of `wasmer` called `wasmer-headless` will now be included with releases. `wasmer-headless` is the `wasmer` VM without any compilers attached, so it can only run precompiled Wasm modules.
- [#2005](https://github.com/wasmerio/wasmer/pull/2005) Added the arguments `alias` and `optional` to `WasmerEnv` derive's `export` attribute.

### Changed
- [#2006](https://github.com/wasmerio/wasmer/pull/2006) Use `wasmer_enumset`, a fork of the `enumset` crate to work around a breaking change in `syn`
- [#1985](https://github.com/wasmerio/wasmer/pull/1985) Bump minimum supported Rust version to 1.48

### Fixed
- [#2007](https://github.com/wasmerio/wasmer/pull/2007) Fix packaging of wapm on Windows
- [#2005](https://github.com/wasmerio/wasmer/pull/2005) Emscripten is now working again.

### Changed
- [#1979](https://github.com/wasmerio/wasmer/pull/1979) `WasmPtr::get_utf8_string` was renamed to `WasmPtr::get_utf8_str` and made `unsafe`.

### Fixed
- [#1979](https://github.com/wasmerio/wasmer/pull/1979) `WasmPtr::get_utf8_string` now returns a `String`, fixing a soundness issue in certain circumstances. The old functionality is available under a new `unsafe` function, `WasmPtr::get_utf8_str`.

## 1.0.0-rc1 - 2020-12-23

### Added

* [#1894](https://github.com/wasmerio/wasmer/pull/1894) Added exports `wasmer::{CraneliftOptLevel, LLVMOptLevel}` to allow using `Cranelift::opt_level` and `LLVM::opt_level` directly via the `wasmer` crate

- [#1949](https://github.com/wasmerio/wasmer/pull/1949) The `wasm_frame_vec_t`, `wasm_functype_vec_t`, `wasm_globaltype_vec_t`, `wasm_memorytype_vec_t`, and `wasm_tabletype_vec_t` are now boxed vectors in the Wasmer C API

* [#1911](https://github.com/wasmerio/wasmer/pull/1911) Generalized signature type in `Function::new` and `Function::new_with_env` to accept owned and reference `FunctionType` as well as array pairs. This allows users to define signatures as constants. Implemented `From<([Type; $N], [Type; $M])>` for `FunctionType` to support this.

### Changed

### Changed

- [#1739](https://github.com/wasmerio/wasmer/pull/1739) Environments passed to host function- must now implement the `WasmerEnv` trait. You can implement it on your existing type with `#[derive(WasmerEnv)]`.
- [#1838](https://github.com/wasmerio/wasmer/pull/1838) Deprecate `WasiEnv::state_mut`: prefer `WasiEnv::state` instead.
- [#1663](https://github.com/wasmerio/wasmer/pull/1663) Function environments passed to host functions now must be passed by `&` instead of `&mut`. This is a breaking change.

- [#1841](https://github.com/wasmerio/wasmer/pull/1841) We will now panic when attempting to use a native function with a captured env as a host function. Previously this would silently do the wrong thing. See [#1840](https://github.com/wasmerio/wasmer/pull/1840) for info about Wasmer's support of closures as host functions.
- [#1764](https://github.com/wasmerio/wasmer/pull/1764) Fix bug in WASI `path_rename` allowing renamed files to be 1 directory below a preopened directory.
