### Bug fixes

Allow all forms of member expressions to be parenthesized as lvalue.

## 4.0.10 (2017-02-07)

functions, even when already in strict mode.

targets, so that `(x) = 1` parses again.

even relatively small source files) introduced by the new 'use strict'
check.

### Bug fixes

Disallow parenthesized pattern expressions.

Allow keywords as export names.

Fix crash when `export` was followed by a keyword that can't be
exported.

## 4.0.3 (2016-08-16)

branches in loose mode. Forbid them entirely in strict mode.

of arrow functions.

## 4.0.0 (2016-08-07)

### Breaking changes

The default `ecmaVersion` option value is now 7.

A number of internal method signatures changed, so plugins might need
to be updated.

### Bug fixes

The parser now raises errors on duplicated export names.

`arguments` and `eval` can now be used in shorthand properties.

Duplicate parameter names in non-simple argument lists now always
produce an error.

### New features

The `ecmaVersion` option now also accepts year-style version numbers
(2015, etc).

Support for `async`/`await` syntax when `ecmaVersion` is >= 8.

Support for trailing commas in call expressions when `ecmaVersion`
is >= 8.

## 3.3.0 (2016-07-25)

### Bug fixes

Fix bug in tokenizing of regexp operator after a function declaration.

Fix parser crash when parsing an array pattern with a hole.

### New features

environment.

rather than copying properties into a fresh object.

## 3.1.0 (2016-04-18)

### Bug fixes

Fix issue where the loose parser created invalid TemplateElement nodes
for unclosed template literals.

Properly tokenize the division operator directly after a function
expression.

Allow trailing comma in destructuring arrays.

operator.

## 3.0.2 (2016-02-10)

### Breaking changes

The default value of the `ecmaVersion` option is now 6 (used to be 5).

Support for comprehension syntax (which was dropped from the draft
spec) has been removed.

### Fixes

`let` and `yield` are now “contextual keywords”, meaning you can
mostly use them as identifiers in ES5 non-strict code.

A parenthesized class or function expression after `export default` is
now parsed correctly.

### New features

When `ecmaVersion` is set to 7, Acorn will parse the exponentiation
operator (`**`).

The identifier character ranges are now based on Unicode 8.0.0.

Plugins can now override the `raiseRecoverable` method to override the
way non-critical errors are handled.
