[#1450](https://github.com/rustwasm/wasm-bindgen/pull/1450)
[#1490](https://github.com/rustwasm/wasm-bindgen/pull/1490)
* A new `skip` attribute to `#[wasm_bindgen]` has been added to skip fields and
methods when generating bindings.
[#1410](https://github.com/rustwasm/wasm-bindgen/pull/1410)
* More bindings have been added to `web-sys` for interfaces tagged with
`[NoInterfaceObject]` in WebIDL. These types always fail `dyn_ref` and friends
and must be manually casted into.

* The `Closure` type now always implements `Debug`.
[#1408](https://github.com/rustwasm/wasm-bindgen/pull/1408)
* Closures which take one `&T` argument are now supported. More implementations
may be added in the future, but for now it's just one argument closures.
[#1417](https://github.com/rustwasm/wasm-bindgen/pull/1417)
* The TypeScript bindings for `--web` now expose the `init` function.
[#1412](https://github.com/rustwasm/wasm-bindgen/pull/1412)
* A `js_sys::JsString::is_valid_utf16` method has been added to handle unpaired
surrogates in JS strings. Surrounding documentation has also been updated to
document this potential pitfall.
[#1416](https://github.com/rustwasm/wasm-bindgen/pull/1416)
* A `wasm_bindgen::function_table()` function has been added to expose the
`WebAssembly.Table` and get access to it in wasm code.
[#1431](https://github.com/rustwasm/wasm-bindgen/pull/1431)
### Fixed
* Reexporting the `wasm_bindgen` macro in crates has been fixed.
[#1359](https://github.com/rustwasm/wasm-bindgen/pull/1359)

## 0.2.40
Released 2019-03-21.
### Added
* TypeScript and JS generation will now attempt to preserve argument names in
the generated JS where possible.
[#1344](https://github.com/rustwasm/wasm-bindgen/pull/1344)
* Enable `Option<T>` support for enums defined in WebIDL.
[#1350](https://github.com/rustwasm/wasm-bindgen/pull/1350)
* Add a `raw_module` attribute to `#[wasm_bindgen]` which is the same as
`module` except doesn't attempt to recognize `./`, `../`, `or `/` prefixed
paths.
[#1353](https://github.com/rustwasm/wasm-bindgen/pull/1353)
* The `wasm-bindgen` CLI flags have now all been renamed under a `--target`
flag. Instead of `--web` you'll now pass `--target web`, for example. This
increases consistency between the `wasm-bindgen` and `wasm-pack` CLI.
[#1369](https://github.com/rustwasm/wasm-bindgen/pull/1369)
### Fixed
* Definitions for `TypedArray` imports of `js-sys` have been unified with a
macro to improve consistency and fix future bugs.

already.
[#1330](https://github.com/rustwasm/wasm-bindgen/pull/1330)
### Fixed
* A bug where if `nom` was in a crate graph and was compiled with the
`verbose-errors` feature has been fixed. Previously the `wasm-bindgen-webidl`
crate wouldn't compile, and now it will.

avoid conflicts with other crates that have a `Context` type being exported.
[#1280](https://github.com/rustwasm/wasm-bindgen/pull/1280)
* The headless test runner for Safari on macOS High Sierra has been fixed.
[#1298](https://github.com/rustwasm/wasm-bindgen/pull/1298)
### Changed
* The `wasm-bindgen` CLI tool now emits the `producers` section again with
relevant bugs having been fixed in the meantime. The
`--remove-producers-section` flag can continue to be used to omit emission of
this section.
[#1263](https://github.com/rustwasm/wasm-bindgen/pull/1263)
--------------------------------------------------------------------------------
## 0.2.37
Released 2019-02-15.

`f64` indices.
[#1225](https://github.com/rustwasm/wasm-bindgen/pull/1225).
* A `--remove-producers-section` flag has been added to the CLI tool to, well,
remove the `producers` section from the final wasm file.
[#1256](https://github.com/rustwasm/wasm-bindgen/pull/1256).
### Fixed
* The `wasm-bindgen` CLI tool will correctly strip DWARF debug information
unless `--keep-debug` is passed.
[#1255](https://github.com/rustwasm/wasm-bindgen/pull/1255).
### Changed
* The `wasm-bindgen` CLI tool no longer emits the `producers` custom section by
default to work around a [webpack bug]. See
[#1260](https://github.com/rustwasm/wasm-bindgen/pull/1260).
[webpack bug]: https://github.com/webpack/webpack/pull/8786
--------------------------------------------------------------------------------
## 0.2.36
Released 2019-02-12.
### Fixed
* Fixed a bug where using closures and LTO together caused a panic inside the
`wasm-bindgen` CLI tool. See
[#1244](https://github.com/rustwasm/wasm-bindgen/issues/1244).
--------------------------------------------------------------------------------
## 0.2.35
Released 2019-02-12.
### Changed
* `wasm-bindgen` now internally uses the `walrus` crate to perform its
transformations of the wasm that rustc/LLVM emits. See
[#1237](https://github.com/rustwasm/wasm-bindgen/pull/1237).
### Fixed
* When `WebAssembly.instantiateStreaming` fails due to incorrect MIME type,
*actually* properly recover. See
[#1243](https://github.com/rustwasm/wasm-bindgen/pull/1243).
--------------------------------------------------------------------------------
## 0.2.34
Released 2019-02-11.
### Added
* Added support for optional `enum`s. See
[#1214](https://github.com/rustwasm/wasm-bindgen/pull/1214).
* Added the `UnwrapThrowExt<T>` trait, which can enable smaller code sizes for
panics. See [#1219](https://github.com/rustwasm/wasm-bindgen/pull/1219).
### Fixed
* Some `WebGlRenderingContext` methods are now whitelisted to use shared slices
instead of exclusive slices. See
[#1199](https://github.com/rustwasm/wasm-bindgen/pull/1199).
* Fixed TypeScript definitions for optional types. See
[#1201](https://github.com/rustwasm/wasm-bindgen/pull/1201).
* Quiet clippy warnings inside generated code. See
[1207](https://github.com/rustwasm/wasm-bindgen/pull/1207).
* Fixed using `cfg_attr` and `wasm_bindgen` together like `#[cfg_attr(...,
wasm_bindgen)]`. See
[1208](https://github.com/rustwasm/wasm-bindgen/pull/1208).
* The WebAudio example program was fixed. See
[#1215](https://github.com/rustwasm/wasm-bindgen/pull/1215).
* Fixed logging HTML in `wasm-bindgen-test`. See
[#1233](https://github.com/rustwasm/wasm-bindgen/pull/1233).
* When `WebAssembly.instantiateStreaming` fails due to incorrect MIME type,
properly recover. See
[#1235](https://github.com/rustwasm/wasm-bindgen/pull/1235).
--------------------------------------------------------------------------------
## 0.2.33
Released 2019-01-18.
### Added

* Bindings for `JSON.stringify` and its optional arguments have been added
[#1190](https://github.com/rustwasm/wasm-bindgen/pull/1190)
### Fixed
* A bug with windows binaries being released has ben resolved.
--------------------------------------------------------------------------------
## 0.2.32
Released 2019-01-16.
### Added
* Added support for Web IDL sequences. This enabled bindings generation for a
couple more Web APIs. We generate functions for Web APIs that take sequences
to accept any iterable, and for Web APIs that return sequences, a
`js_sys::Array` is returned. See
[#1152](https://github.com/rustwasm/wasm-bindgen/pull/1152) and
[#1038](https://github.com/rustwasm/wasm-bindgen/issues/1038).
* The `wasm-bindgen-test` test runner will capture `console.debug`,
`console.info`, and `console.warn` log messages and print them to `stdout`
now. It already supported `console.log` and `console.error` and continues to
support them. See
[#1183](https://github.com/rustwasm/wasm-bindgen/issues/1183) and
[#1184](https://github.com/rustwasm/wasm-bindgen/pull/1184).
* Added additional `--debug`-only assertions in the emitted JS glue for cases
where an imported JS function that is not annotated with
`#[wasm_bindgen(catch)]` throws an exception. This should help catch some bugs
earlier! See [#1179](https://github.com/rustwasm/wasm-bindgen/pull/1179).
### Fixed
* Fixed a bug where `#[wasm_bindgen_test]` tests would fail in non-headless Web
browsers if they used `console.log`. See
[#1167](https://github.com/rustwasm/wasm-bindgen/pull/1167).
* Fixed a bug where returning closures from exported functions sometimes
resulted in a faulty error. See
[#1174](https://github.com/rustwasm/wasm-bindgen/issues/1174) and
[#1175](https://github.com/rustwasm/wasm-bindgen/pull/1175).
* Sometimes our generated TypeScript interface files had syntax errors in them
(missing semicolons). This has been fixed. See
[#1181](https://github.com/rustwasm/wasm-bindgen/pull/1181).
--------------------------------------------------------------------------------
## 0.2.31
Released 2019-01-09.

module.
[#1084](https://github.com/rustwasm/wasm-bindgen/pull/1084)
* Support for importing the `default` export has been added.
[#1106](https://github.com/rustwasm/wasm-bindgen/pull/1106)

[#1117](https://github.com/rustwasm/wasm-bindgen/pull/1117)
### Fixed
* A small bug with LTO and closures has been fixed.
[#1145](https://github.com/rustwasm/wasm-bindgen/pull/1145)
--------------------------------------------------------------------------------
## 0.2.29
Released 2018-12-04.
### Added
* Add a `#[wasm_bindgen(start)]` attribute to customize the `start` section of
the wasm module.
[#1057](https://github.com/rustwasm/wasm-bindgen/pull/1057)
* Add support for producing the new "producers" section of wasm binaries
[#1041](https://github.com/rustwasm/wasm-bindgen/pull/1041)
* Add support a `typescript_custom_section` attribute for producing custom
typescript abstractions
[#1048](https://github.com/rustwasm/wasm-bindgen/pull/1048)
* Generate `*.d.ts` files for wasm files in addition to the JS bindings
[#1053](https://github.com/rustwasm/wasm-bindgen/pull/1053)
* Add a feature to assert that all attributes in `#[wasm_bindgen]` are used to
help catch typos and mistakes
[#1055](https://github.com/rustwasm/wasm-bindgen/pull/1055)
### Changed
* JS glue generation has received a few small optimizations such as removing
shims and removing object allocations
[#1033](https://github.com/rustwasm/wasm-bindgen/pull/1033)
[#1030](https://github.com/rustwasm/wasm-bindgen/pull/1030)
* JS glue now just uses one array of JS objects instead of two
[#1069](https://github.com/rustwasm/wasm-bindgen/pull/1069)
### Fixed
* Fix a typo in the `--no-modules` generated JS
[#1045](https://github.com/rustwasm/wasm-bindgen/pull/1045)
--------------------------------------------------------------------------------
## 0.2.28
Released 2018-11-12.
### Added
* The `js_class` support is now supported on exported types to define a
different class in JS than is named in Rust
[#1012](https://github.com/rustwasm/wasm-bindgen/pull/1012)
* More WebIDL bindings are exposed with some internal restructuring to ignore
unimplemented types at a different location
[#1014](https://github.com/rustwasm/wasm-bindgen/pull/1014)
* All imported types now implement `Deref` to their first `extends` attribute
(or `JsValue` if one isn't listed). This is intended to greatly improve the
ergonomics of `web-sys` bindings by allowing easy access to parent class
methods
[#1019](https://github.com/rustwasm/wasm-bindgen/pull/1019)
* A new attribute, `final`, can be applied to JS imports. This attribute is
relatively nuanced and [best explained in documentation][final-dox], but is
added since `structural` is now the default
[#1019](https://github.com/rustwasm/wasm-bindgen/pull/1019)
[final-dox]: https://rustwasm.github.io/wasm-bindgen/reference/attributes/on-js-imports/final.html
* A new CLI flag, `--remove-name-section`, can be passed to remove the wasm
`name` section which contains the names of functions for debugging (typically
not needed in release mode)
[#1024](https://github.com/rustwasm/wasm-bindgen/pull/1024)
### Changed
* All imported functions are now `structural` by default. This shouldn't change
the semantics of imported functions, only how they're invoked in the JS
function shims that are generated by `wasm-bindgen`. More discussion can be
founed on [RFC 5] and the PR
[#1019](https://github.com/rustwasm/wasm-bindgen/pull/1019)
[RFC 5]: https://rustwasm.github.io/rfcs/005-structural-and-deref.html
* JS glue assertions for moved arguments are now only emitted in debug mode,
which is still off by default
[#1020](https://github.com/rustwasm/wasm-bindgen/pull/1020)
### Fixed
* Typescript generated bindings now correctly reflect `Option<T>` for more types
[#1008](https://github.com/rustwasm/wasm-bindgen/pull/1008)
* The JS shim code generation has been optimized for `structural` bindings (now
the default) to include fewer JS shims and more easily optimizable for JS
engines
[#1019](https://github.com/rustwasm/wasm-bindgen/pull/1019)
* Passing a `WebAssembly.Module` to the `--no-modules` constructor has been
fixed
[#1025](https://github.com/rustwasm/wasm-bindgen/pull/1025)
--------------------------------------------------------------------------------
## 0.2.27
Released 2018-10-29.
### Fixed
* Fixed an internal panic where the gc passes were being too aggressive
[#995](https://github.com/rustwasm/wasm-bindgen/pull/995)
--------------------------------------------------------------------------------
## 0.2.26
Released 2018-10-29.
### Added
* The `TypedArray.slice` methods have now been bound in `js-sys`.
[#956](https://github.com/rustwasm/wasm-bindgen/pull/956)
* The `Debug` and `Clone` traits are now implemented for `js_sys::Promise`.
[#957](https://github.com/rustwasm/wasm-bindgen/pull/957)
* The `js_sys::DataView` type now exposes overloads to specify endianness.
[#966](https://github.com/rustwasm/wasm-bindgen/pull/966)
* When using `--no-modules` a `WebAssembly.Module` can now be directly passed
into the instantiation glue.
[#969](https://github.com/rustwasm/wasm-bindgen/pull/969)
### Fixed
* The `JsValue` type is no longer considered `Send`.
[#955](https://github.com/rustwasm/wasm-bindgen/pull/955)
* The generated JS glue is now more robust in the face of missing APIs.
[#959](https://github.com/rustwasm/wasm-bindgen/pull/959)
* An issue with the latest version of `safaridriver` used to run headless tests
has been resolved.
[#991](https://github.com/rustwasm/wasm-bindgen/pull/991)
--------------------------------------------------------------------------------
## 0.2.25
Released 2018-10-10.
### Fixed
* Using `wasm-bindgen` will no longer unconditionally pull in Rust's default
allocator for Wasm (dlmalloc) regardless if you configured a custom global
allocator (eg wee_alloc).
[#947](https://github.com/rustwasm/wasm-bindgen/pull/947)
* Fixed web-sys build on some Windows machines.
[#943](https://github.com/rustwasm/wasm-bindgen/issues/943)
* Fixed generated ES class bindings to Rust structs that were only referenced
through struct fields.
[#948](https://github.com/rustwasm/wasm-bindgen/issues/948)
--------------------------------------------------------------------------------
## 0.2.24
Released 2018-10-05.
### Added
* Constructors for types in `web-sys` should now have better documentation.
* A new `vendor_prefix` attribute in `#[wasm_bindgen]` is supported to bind APIs
on the web which may have a vendor prefix (like `webkitAudioContext`). This is
then subsequently used to fix `AudioContext` usage in Safari.
* The `#[wasm_bindgen(extends = Foo)]` attribute now supports full paths, so you
can also say `#[wasm_bindgen(extends = foo::Bar)]` and such.
### Changed
* The `Closure<T>` type is now optimized when the underlying closure is a ZST.
The type now no longer allocates memory in this situation.
* The documentation now has a list of caveats for browser support, including how
`TextEncoder` and `TextDecoder` are not implemented in Edge. If you're using
webpack there's a listed strategy available, and improvements to the polyfill
strategy are always welcome!
* The `BaseAudioContext` and `AudioScheduledSourceNode` types in `web-sys` have
been deprecated as they don't exist in Safari or Edge.
### Fixed
* Fixed the `#[wasm_bindgen_test]`'s error messages in a browser to correctly
escape HTML-looking output.
* WebIDL Attributes on `Window` are now correctly bound to not go through
`Window.prototype` which doesn't exist but instead use a `structural`
definition.
* Fixed a codegen error when the `BorrowMut` trait was in scope.
* Fixed TypeScript generation for constructors of classes, it was accidentally
producing a syntactially invalid file!
--------------------------------------------------------------------------------
## 0.2.23
Released 2018-09-26.
### Added
* [This is the first release of the `web-sys`
crate!](https://rustwasm.github.io/2018/09/26/announcing-web-sys.html)
* Added support for unions of interfaces and non-interfaces in the WebIDL
frontend.
* Added a policy for inclusion of new ECMAScript features in `js-sys`: the
feature must be in stage 4 or greater for us to support it.
* Added some documentation about size profiling and optimization with
`wasm-bindgen` to the guide.
* Added the `Clamped<T>` type for generating JavaScript `Uint8ClampedArray`s.
* CI is now running on beta! Can't wait for the `rustc` release trains to roll
over, so we can run CI on stable too!
* Added the `js_sys::try_iter` function, which checks arbitrary JS values for
compliance with the JS iteration protocol, and if they are iterable, converts
them into an iterator over the JS values that they yield.
### Changed
* We now only generate null checks on methods on the JS side when in debug
mode. For safety we will always null check on the Rust side, however.
* Improved error messages when defining setters that don't start with `set_` and
don't use `js_name = ...`.
* Improved generated code for classes in a way that avoids an unnecessary
allocation with static methods that return `Self` but are not the "main"
constructor.
* **BREAKING:** `js_sys::Reflect` APIs are all fallible now. This is because
reflecting on `Proxy`s whose trap handlers throw an exception can cause any of
the reflection APIs to throw. Accordingly, `js_sys` has been bumped from
`0.2.X` to `0.3.X`.
### Fixed
* The method of ensuring that `__wbindgen_malloc` and `__wbindgen_free` are
always emitted in the `.wasm` binary, regardless of seeming reachability is
now zero-overhead.
--------------------------------------------------------------------------------
## 0.2.22
Released 2018-09-21
### Added
* The `IntoIterator` trait is now implemented for JS `Iterator` types
* A number of variadic methods in `js-sys` have had explicit arities added.
* The guide has been improved quite a bit as well as enhanced with more examples
* The `js-sys` crate is now complete! Thanks so much to everyone involved to
help fill out all the APIs.
* Exported Rust functions with `#[wasm_bindgen]` can now return a `Result` where
the `Err` payload is raised as an exception in JS.
### Fixed
* An issue with running `wasm-bindgen` on crates that have been compiled with
LTO has been resolved.
--------------------------------------------------------------------------------
## 0.2.21
Released 2018-09-07
### Added
* Added many more bindings for `WebAssembly` in the `js-sys` crate.
### Fixed
* The "names" section of the wasm binary is now correctly preserved by
wasm-bindgen.
--------------------------------------------------------------------------------
## 0.2.20
Released 2018-09-06
### Added
* All of `wasm-bindgen` is configured to compile on stable Rust as of the
upcoming 1.30.0 release, scheduled for October 25, 2018.
* The underlying `JsValue` of a `Closure<T>` type can now be extracted at any
time.
* Initial and experimental support was added for modules that have shared memory
(use atomic instructions).
### Removed
* The `--wasm2asm` flag of `wasm2es6js` was removed because the `wasm2asm` tool
has been removed from upstream Binaryen. This is replaced with the new
`wasm2js` tool from Binaryen.
### Fixed
* The "schema" version for wasm-bindgen now changes on all publishes, meaning we
can't forget to update it. This means that the crate version and CLI version
must exactly match.
* The `wasm-bindgen` crate now has a `links` key which forbids multiple versions
of `wasm-bindgen` from being linked into a dependency graph, fixing obscure
linking errors with a more first-class error message.
* Binary releases for Windows has been fixed.
--------------------------------------------------------------------------------
## 0.2.19 (and 0.2.18)
Released 2018-08-27.
### Added
* Added bindings to `js-sys` for some `WebAssembly` types.
* Added bindings to `js-sys` for some `Intl` types.
* Added bindings to `js-sys` for some `String` methods.
* Added an example of using the WebAudio APIs.
* Added an example of using the `fetch` API.
* Added more `extends` annotations for types in `js-sys`.
* Experimental support for `WeakRef` was added to automatically deallocate Rust
objects when gc'd.
* Added support for executing `wasm-bindgen` over modules that import their
memory.
* Added a global `memory()` function in the `wasm-bindgen` crate for accessing
the JS object that represent wasm's own memory.
### Removed
* Removed `AsMut` implementations for imported objects.
### Fixed
* Fixed the `constructor` and `catch` attributes combined on imported types.
* Fixed importing the same-named static in two modules.
--------------------------------------------------------------------------------
## 0.2.17
Released 2018-08-16.
### Added
* Greatly expanded documentation in the wasm-bindgen guide.
* Added bindings to `js-sys` for `Intl.DateTimeFormat`
* Added a number of `extends` attributes for types in `js-sys`
### Fixed
* Fixed compile on latest nightly with latest `proc-macro2`
* Fixed compilation in some scenarios on Windows with paths in `module` paths
--------------------------------------------------------------------------------
## 0.2.16
Released 2018-08-13.
### Added
* Added the `wasm_bindgen::JsCast` trait, as described in [RFC #2][rfc-2].
* Added [the `#[wasm_bindgen(extends = ...)]` attribute][extends-attr] to
describe inheritance relationships, as described in [RFC #2][rfc-2].
* Added support for receiving `Option<&T>` parameters from JavaScript in
exported Rust functions and methods.
* Added support for receiving `Option<u32>` and other option-wrapped scalars.
* Added reference documentation to the guide for every `#[wasm_bindgen]`
attribute and how it affects the generated bindings.
* Published the `wasm-bindgen-futures` crate for converting between JS
`Promise`s and Rust `Future`s.
### Changed
* Overhauled the guide's documentation on passing JS closures to Rust, and Rust
closures to JS.
* Overhauled the guide's documentation on using serde to serialize complex data
to `JsValue` and deserialize `JsValue`s back into complex data.
* Static methods are now always bound to their JS class, as is required for
`Promise`'s static methods.
### Removed
* Removed internal usage of `syn`'s `visit-mut` cargo feature, which should
result in faster build times.
### Fixed
* Various usage errors for the `#[wasm_bindgen]` proc-macro are now properly
reported with source span information, rather than `panic!()`s inside the
proc-macro.
* Fixed a bug where taking a struct by reference and returning a slice resulted
in lexical variable redeclaration errors in the generated JS glue. [#662][]
* The `#[wasm_bindgen(js_class = "....")]` attribute for binding methods to
renamed imported JS classes now properly works with constructors.

--------------------------------------------------------------------------------
## 0.2.15
Released 2018-07-26.
### Fixed
* Fixed `wasm-bindgen` CLI version mismatch checks that got broken in the last
point release.
--------------------------------------------------------------------------------
## 0.2.14

Mach-O. [#545](https://github.com/rustwasm/wasm-bindgen/issues/545)
--------------------------------------------------------------------------------
## 0.2.13
Released 2018-07-22.
### Added
* Support the `#[wasm_bindgen(js_name = foo)]` attribute on exported functions
and methods to allow renaming an export to JS. This allows JS to call it by
one name and Rust to call it by another, for example using `camelCase` in JS
and `snake_case` in Rust
### Fixed
* Compilation with the latest nightly compiler has been fixed (nightlies on and
after 2018-07-21)
--------------------------------------------------------------------------------
## 0.2.12
Released 2018-07-19.
This release is mostly internal refactorings and minor improvements to the
existing crates and functionality, but the bigs news is an upcoming `js-sys` and
`web-sys` set of crates. The `js-sys` crate will expose [all global JS
bindings][js-all] and the `web-sys` crate will be generated from WebIDL to
expose all APIs browsers have. More info on this soon!
[js-all]: https://github.com/rustwasm/wasm-bindgen/issues/275
### Added
* Support for `Option<T>` was added where `T` can be a number of slices or
imported types.
* Comments in Rust are now preserved in generated JS bindings, as well as
comments being generated to indicate the types of arguments/return values.
* The online documentation has been reorganized [into a book][book].
* The generated JS is now formatted better by default for readability.
* A `--keep-debug` flag has been added to the CLI to retain debug sections by
default. This happens by default when `--debug` is passed.
[book]: https://rustwasm.github.io/wasm-bindgen/
### Fixed
* Compilation with the latest nightly compiler has been fixed (nightlies on and
after 2018-07-19)
* Declarations of an imported function in multiple crates have been fixed to not
conflict.
* Compilation with `#![deny(missing_docs)]` has been fixed.
