* **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.
|

|
||||||
|
* **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.
|

* **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.
|
||||||
|
* Added missing exponential operator inlining. Thanks [@nkt](https://github.com/nkt)!
|
||||||

|
* **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.

|
||||||
|
* Make UID generation based on module declarations **much** nicer.
|
||||||
|
* **Internal**
|
||||||
|

|
||||||

|
||||||
|
* **Internal**
|
||||||

|
||||||
|
|
||||||
|

|
* **Bug Fix**
|
||||||
|
* Fix regression in `node/register` that caused `node_modules` to not be ignored.
|
||||||
|
|
||||||
|
## 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)!
|
||||||
|
* Fix `resolveRc` running on files twice causing issues. Thanks [@lukescott](https://github.com/lukescott)!
|
||||||

|
||||||
|
* **Polish**
|
||||||
|
* 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.
|
||||||
|
* Add `retainLines` option that retains the line (but not the columns!) of the input code.
|
||||||
|
|
||||||
|
## 5.1.13
