|
|
|
|
* **Bug Fix**
|
|
* `babel-helper-remap-async-to-generator`: [#3288](https://github.com/babel/babel/pull/3288) Async arrow functions should compile to regular functions because they reference `arguments`.
|
|
|
|
## 6.4.5 (2016-01-19)
|
|
|
|
* **Bug Fix**
|
|
* `babel-plugin-transform-es2015-modules-commonjs`: [#3118](https://github.com/babel/babel/pull/3118) Fix bad import hoisting interaction (copy `_blockHoist` values) regarding import statements. ([T6738](https://phabricator.babeljs.io/T6738)). Thanks @benjamn for your patience for this one!
|
|
- This fixes:
|
|
```js
|
|
var _templateObject = (0, _taggedTemplateLiteral3.default)(["foo"], ["foo"]); // this should come after _taggedTemplateLiteral 2 and 3
|
|
var _taggedTemplateLiteral2 = require("babel-runtime/helpers/taggedTemplateLiteral");
|
|
var _taggedTemplateLiteral3 = _interopRequireDefault(_taggedTemplateLiteral2);
|
|
|
|
tag(_templateObject);
|
|
```
|

|
|

|
|
```js
|
|
class A {

|
|
- This fixes a specific issue with the [react preset](https://babeljs.io/docs/plugins/preset-react/) since it includes `syntax-flow` and `transform-flow-strip-types` which caused an issue with the flow types not to be stripped and the general case of other people are including the flow syntax option in their own plugins.

## 5.5.1

|
* **Bug Fix**
|
|
* Remove `ClassProperty` nodes always in the `Flow` transformer. This is fine now since class properties aren't supported in any engine that supports classes but the `es7.classProperties` transformer will need to be updated in the future to desugar to ES6 classes instead of relying on the `es6.classes` transformer from being ran.

|
* When performing single-reference inlining, ensure that the single reference isn't a child of the binding itself.

|
|
* Fix bug with paren printing in `compact` and `retainLines` mode where a left paren was already printed before catching up.
|
|
* **Internal**

|
|
* **Polish**
|
|
* Clean up `shouldIgnore` algorithm to work how you'd expect rather than being a hacky piece of shit. It now crawls the entire path, checking each section of it against the input ignore/only patterns. This means that the pattern `foo` will ignore the paths `foo/bar.js`, `bar/foo` etc.
|
|
|
|
## 5.4.0

|
* **New Feature**

* **Polish**
|
|
* Normalise path separators for souce map paths when using `$ babel`.
|
|
* Rework `PathHoister` to ignore global references and to not deopt on reassignments to referenced bindings, instead it tries to hoist to the highest scope.

|
|
* Properly hoist temp param declarations when doing TCO.
|
|
* **Internal**
|
|
* Add `--harmony_generators` flag to `$ babel-node`.
|
|
* Internal AST traversals have been minimised **drastically**. Transformers have been grouped together which means entire tree traversals are much fewer. Visiting nodes is now also skipped if the traversal context can detect that the handler is a noop. This sames precious cycles as it avoids constructing traversal paths and creating a new traversal context. See issues [#1472](https://github.com/babel/babel/issues/1472) and [#1486](https://github.com/babel/babel/issues/1486) for related discussion.

|
|
* Remove internal check for traversal path replacement of self. This is a pattern that **could** come up in the wild and it could lead to pretty nasty code and may lead to internal regressions as the test coverage isn't 100% :( Instead, just put it in the fast path.

## 5.2.0
|
|
|
|
* **Bug Fix**
|
|
* Fix plugin strings splitting arbitrarily on `:` which caused full paths on Windows to fail as they include `:` after the drive letter.
|
|
* Call class property `initializer`s with their target instead of their descriptor.
|
|
* Fix `ignore` and `only` not properly working on Windows path separators. Thanks [@stagas](https://github.com/stagas)!

|
|
* Allow passing an array of globs to `babel/register` `only` and `ignore` options. Thanks [@Mark-Simulacrum](https://github.com/Mark-Simulacrum)!
|
|
* When inferring function names that collide with upper bindings, instead of doing the wrapper, instead rename them.
|
|
* Consider constant-like variable declaration functions to always refer to themselves so TOC can be performed.
|
|
* Process globs manually when using `$ babel` as some shells such as Windows don't explode them. Thanks [@jden](https://github.com/jden)!
|
|
* Add alternative way to execute plugins via a closure that's called with the current Babel instance.
|
|
* **Internal**
|
|
* Remove multiple internal transformers in favor of directly doing things when we need to. Previously, declarations such as `_ref` that we needed to create in specific scopes were done at the very end via the `_declarations` transformer. Now, they're done and added to the scope **right** when they're needed. This gets rid of the crappy `_declarations` property on scope nodes and fixes the crappy regenerator bug where it was creating a new `BlockStatement` so the declarations were being lost.
|
|
* Rework transformer traversal optimisation. Turns out that calling a `check` function for **every single node** in the AST is ridiculously expensive. 300,000 nodes timesed by ~30 transformers meant that it took tens of seconds to perform while it's quicker to just do the unnecessary traversal. Seems obvious in hindsight.
|
|
* **New Feature**
|
|
* Add `jscript` transformer that turns named function expressions into function declarations to get around [JScript's horribly broken function expression semantics](https://kangax.github.io/nfe/#jscript-bugs). Thanks [@kondi](https://github.com/kondi)!

* Add `@@hasInstance` support to objects when using the `es6.spec.symbols` transformer.
