+  * Update AMD module formatter to add import default remapping.
+
+## 5.4.3
+
+ * **Bug Fix**
+  * Fix `module` being incorrectly rewritten when used as in an export declaration.
+  * When performing single-reference inlining, ensure that the single reference isn't a child of the binding itself.
+  * Fix a bug in `minification.deadCodeElimination` where a new binding instance was being created for local class bindings instead of just inheriting the parent one.
+  * Fix bug with paren printing in `compact` and `retainLines` mode where a left paren was already printed before catching up.
+ * **Internal**
+  * Handle contexts for paths much better. This will ensure that the path node location info is in sync.
+
+## 5.4.2
+
+ * **Polish**
+  * `ignore` and `only` patterns are now **very** liberal. The pattern can now exist anywhere in the path.
+
+## 5.4.1
+
+ * **Bug Fix**
+  * Add missing `slash` dependency. Thanks [@browncolyn](https://github.com/browncolyn)!
+ * **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**
+  * Added [function bind syntax](https://github.com/zenparsing/es-function-bind) behind stage 0. Thanks [@RReverser](https://github.com/rreverser)!
+  * Added `env` option. Especially handy when using the `.babelrc`.
+ * **Bug Fix**
+  * Fix files not properly being ignored when `babel.transform` ignores them when using `$ babel`.
+  * Fix scope tracking registering loop head bindings to their `VariableDeclaration` instead of `VariableDeclarator`.
+ * **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)!
+  * Optimise `regenerator` transformer. Thanks [@benjamn](https://github.com/benjamn)!
+
+## 5.3.3
+
+ * **Bug Fix**
+  * Fix `minification.deadCodeElimination` transformer incorrectly trying to inline import declarations.
+  * Fix `minification.inlineExpression` transformer getting into an infinite loop.
+
+## 5.3.2
+
+ * **Bug Fix**
+  * Fix patterns not being considered when hoisting variables in the `es6.blockScoping` transformer.
+
+## 5.3.1
+
+ * **Bug Fix**
+  * Fix unique export specifiers not being cloned when exploding class and function exports,
+ * **Polish**
+  * Turn import remaps to sequence expressions to remove their context and improve performance.
+
+## 5.3.0
+
+**Speeeeeeed**

+
+ * **Spec Compliancy**
+  * Allow trailing param commas for methods when using the `es7.trailingCommas` transformer.
+ * **Bug Fix**
+  * Fix `es6.blockScoping` transformer not properly ignoring `break` in `SwitchCase`.
+  * Fix lookahead context saving to avoid weird tokenizer state.
+  * Explode duplicate identifiers in export/import specifiers and property shorthand to create unique objects.
+  * Skip loose mode for class methods when they have decorators.
+  * When removing nodes, share their comments with their siblings.
+  * 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.
+ * **Polish**
+  * Move many `utility` transformers to `minification`.
+
+## 5.2.17
+
+ * **Bug Fix**
+  * Fix auxiliary comments not properly being attached to function declaration helpers.
+  * Add `Super` node type to `ast-types` patch.
+  * Ignore parameter bindings when attempting to inline them in the `minification.deadCodeElimination` transformer.
+  * Correct `extensions` arguments when using the Babel CLI.
+
+## 5.2.16
+
+ * **Bug Fix**
+  * Fix plugins being disabled when using the whitelist.
+  * Fix correct function scope being passed to `nameMethod.property` when inferring the function name for class methods.
+  * Fix incorrect extensions reference causing weird issues when using the Babel CLI.
+  * Fix destructuring param reference replacements not inheriting from their original param.
+ * **Spec Compliancy**
+  * Fix order that method decorators are ran in.
+
+## 5.2.15
+
+ * **Bug Fix**
+  * Fix initializer descriptor add attempt if it doesn't exist.
+
+## 5.2.14
+
+ * **Bug Fix**
+  * Fix bug with initializer decorators where the descriptors weren't being defined if there was no `initializer` property.
+ * **Internal**
+  * Expose `retainLines` option to CLI.
+  * Fix `retainLines` option not being taken into consideration when doing multiple variable declaration declarators generation.
+  * Expose minified and unminified copies of dist scripts.
+
+## 5.2.13
+
+ * **Bug Fix**
+  * Fix `ExportDeclaration`s being incorrectly removed when using the `utility.deadCodeElimination` transformer.
+  * Fix position of `utility` transformers.
+ * **New Feature**
+  * Add built-in `esquery` support.
+ * **Internal**
+  * Consolidate notion of "virtual types".
+
+## 5.2.12
+
+ * **Polish**
+  * Make UID generation based on module declarations **much** nicer.
+ * **Internal**
+  * 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.
+
+## 5.2.11
+
+ * **Internal**
+  * Rename `getModuleName` option to `getModuleId`, doh.
+
+## 5.2.10
+
+ * **Bug Fix**
+  * Fix numerous issues in `replaceWithSourceString`. Thanks [@pangratz](https://github.com/pangratz)!
+ * **New Feature**
+  * Add `getModuleName` option. Thanks [@jayphelps](https://github.com/jayphelps)!
+
+## 5.2.9
+
+ * **Bug Fix**
+  * Fix `_blockHoist` transformer incorrectly sorting nodes on shitty environments that aren't spec compliant in their key order.
+  * Fix broken `parse` API method reference to an undeclared import.
+
+## 5.2.7
+
+ * **Bug Fix**
+  * Move `utility.deadCodeElimination` transformer up to avoid race conditions.
+  * Fix shorthand property scope binding renaming.
+ * **Polish**
+  * Turn helper variable declarations into function declarations if possible.
+ * **Internal**
+  * Removed native inheritance support from classes.
+  * Added `replaceWithSourceString` path API.
+  * Split up `es3.propertyLiterals` and `es3.memberExpressionLiterals` transformers to `minfication.propertyLiterals` and `es3.memberExpressionLiterals`.
+
+## 5.2.6
+
+ * **Internal**
+  * Fix transformer aliases being accidently set as deprecated ones.
+  * Expose `Pipeline` as `TransformerPipeline` instead.
+
+## 5.2.5
+
+ * **Bug Fix**
+  * Fix `parse` API not adding all the correct pipeline transformers.
+
+## 5.2.4
+
+ * **Bug Fix**
+  * Fix race condition with the Node API being loaded awkwardly and not being able to initialise itself when used in the browser.
+ * **Internal**
+  * Expose `transform.pipeline`.
+
+## 5.2.3
+
+ * **Bug Fix**
+  * Fix plugin containers being called with an undefined import. Thanks [@timbur](https://github.com/timbur)!
+  * Allow Flow object separators to be commas. Thanks [@monsanto](https://github.com/monsanto)!
+  * Add missing `Statement` and `Declaration` node aliases to flow types.
+
+## 5.2.2
+
+ * **Internal**
+  * Allow `util.arrayify` to take arbitrary types and coerce it into an array.
+
+## 5.2.1
+
+ * **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)!
+  * Fix shorthand properties not correctly being target for `isReferenced` checks. Thanks [@monsanto](https://github.com/monsanto)!
+ * **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
+
+ * **Polish**
+  * Remove symbol check from `defineProperty` helper.
+
+## 5.1.12
+
+ * **Bug Fix**
+  * Fix `resolveModuleSource` not being ran on `ExportAllDeclaration`s.
+  * Fix `.babelrc` being resolved multiple times when using the require hook.
+  * Fix parse error on spread properties in assignment position.
+  * Fix `externalHelpers` option being incorrectly listed as type `string`.

+  * Remove statements to expression explosion when inserting a block statement.
+ * **Internal**
+  * Remove runtime compatibility check.
+

+
+ * **Bug Fix**

+  * Fix default export specifiers not triggering AMD `module` argument inclusion.
+  * Fix assignments not having their module references properly remapped.
+ * **Internal**
+  * Upgrade to latest `acorn`.

+  * Bump `core-js` version.
+
+## 5.1.4
+
+ * **Polish**
+  * Add missing `Reflect` methods to runtime transformer.
+
+## 5.1.3
+
+ * **Internal**
+  * Switch entirely to vanilla regenerator.
+  * Clean up and make the parsing of decorators stateless.
+ * **Bug Fix**
+  * Don't do TCO on generators and async functions.
+  * Add missing `core-js` runtime definitions.
+
+## 5.1.2
+
+ * **Bug Fix**
+  * Add `getIterator` and `isIterable` to `babel-runtime` build script.

+  * Don't emit tokens when doing a lookahead.
+  * Add missing `test` declaration to `utility.deadCodeElimination` transformer.
+ * **Internal**
+  * Upgrade `regenerator` to the latest and use my branch with the hope of eventually switching to vanilla regenerator.
+  * Add support for the replacement of for loop `init`s with statements.
+  * Upgrade dependencies.
+ * **Polish**
+  * When adding the scope IIFE when using default parameters, don't shadow the function expression, just `apply` `this` and `arguments` if necessary.
+  * Use path basename as non-default import fallback.
+ * **New Feature**
+  * Add [trailing function comma proposal](https://github.com/jeffmo/es-trailing-function-commas). Thanks [@AluisioASG](https://github.com/AluisioASG)!
