Wasmbind

Released 2019-08-14.

Added

* Add binding for `Element.getElementsByClassName`.
[1665](https://github.com/rustwasm/wasm-bindgen/pull/1665)

* `PartialEq` and `Eq` are now implementd for all `web-sys` types.
[1673](https://github.com/rustwasm/wasm-bindgen/pull/1673)

* The `wasm-bindgen-futures` crate now has support for futures when the
experimental WebAssembly threading feature is enabled.
[1514](https://github.com/rustwasm/wasm-bindgen/pull/1514)

* A new `enable-interning` feature is available to intern strings and reduce the
cost of transferring strings across the JS/Rust boundary.
[1612](https://github.com/rustwasm/wasm-bindgen/pull/1612)

* The `wasm-bindgen` CLI has experimental support for reading native
`webidl-bindings` custom sections and generating JS glue. This support is in
addition to Rust's own custom sections and allows using `wasm-bindgen` with
binaries produced by other than rustc possibly.
[1690](https://github.com/rustwasm/wasm-bindgen/pull/1690)

* New environment variables have been added to configure webdriver startup
arguments.
[1703](https://github.com/rustwasm/wasm-bindgen/pull/1703)

* New `JsValue::{is_truthy,is_falsy}` methods are now available.
[1638](https://github.com/rustwasm/wasm-bindgen/pull/1638)

Changed

* JS import shims are now skipped again when they are unnecessary.
[1654](https://github.com/rustwasm/wasm-bindgen/pull/1654)

* WebAssembly output files now directly embed the module/name for imports if
supported for the target and the import, reducing JS shims even further.
[1689](https://github.com/rustwasm/wasm-bindgen/pull/1689)

Fixed

* Support for threads have been updated for LLVM 9 and nightly Rust.
[1675](https://github.com/rustwasm/wasm-bindgen/pull/1675)
[1688](https://github.com/rustwasm/wasm-bindgen/pull/1688)

* The `anyref` passes in `wasm-bindgen` have seen a number of fixes to improve
their correctness and get the full test suite running.
[1692](https://github.com/rustwasm/wasm-bindgen/pull/1692)
[1704](https://github.com/rustwasm/wasm-bindgen/pull/1704)

* Support for `futures-preview 0.3.0-alpha.18` has been added to
`wasm-bindgen-futures`.
[1716](https://github.com/rustwasm/wasm-bindgen/pull/1716)

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

Released 2019-07-11.

Added

* All typed arrays now implement `From` for the corresponding Rust slice type,
providing a safe way to create an instance which copies the data.
[1620](https://github.com/rustwasm/wasm-bindgen/pull/1620)

* `Function::bind{2,3,4}` are now available in `js-sys`.
[1633](https://github.com/rustwasm/wasm-bindgen/pull/1633)

Changed

* More WebGL methods have been updated to use shared slices instead of mutable
slices.
[1639](https://github.com/rustwasm/wasm-bindgen/pull/1639)

* When using the `bundler` target the import of the wasm file now uses the
`.wasm` extension to ensure a wasm file is loaded.
[1646](https://github.com/rustwasm/wasm-bindgen/pull/1646)

* The old internal `Stack` trait has been removed since it is no longer used.
[1624](https://github.com/rustwasm/wasm-bindgen/pull/1624)

Fixed

* The `js_sys::global()` accessor now attempts other strategies before falling
back to a `Function` constructor which can violate some strict CSP settings.
[1650](https://github.com/rustwasm/wasm-bindgen/pull/1649)

* Dropping a `JsFuture` no longer logs a benign error to the console.
[1649](https://github.com/rustwasm/wasm-bindgen/pull/1649)

* Fixed an assertion which could happen in some modules when generating
bindings.
[1617](https://github.com/rustwasm/wasm-bindgen/pull/1617)

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

small edit to the WebIDL.

[1598](https://github.com/rustwasm/wasm-bindgen/pull/1598)

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

Released 2019-05-16.

Added

* Support for exporting "fields" on JS objects wrapping Rust structs which are
hooked up to getters/setters has been added. This is in addition to `pub`
struct fields and allows performing more complicated computations in
getters/setters.
[1440](https://github.com/rustwasm/wasm-bindgen/pull/1440)

* Support for futures 0.3 (and `async` / `await` syntax) has been added to the

[1521](https://github.com/rustwasm/wasm-bindgen/pull/1521)

* Passing ASCII-only strings to WASM should now be significantly faster.
[1470](https://github.com/rustwasm/wasm-bindgen/pull/1470)

* The `selectionStart` and `selectionEnd` APIs of text areas have been enabled.
[1533](https://github.com/rustwasm/wasm-bindgen/pull/1533)

Changed

* Some more methods in `web-sys` now take immutable slices instead of mutable
