# `wasm-bindgen` Change Log

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

## 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.
