# `wasm-bindgen` Change Log

--------------------------------------------------------------------------------

## 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

Released 2018-07-25.

### Fixed

* Fixed compilation errors on targets that use
  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.

### 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.
