Allow object/array patterns in rest parameters.

Don't error when yield is used as a property name.

Allow async as a shorthand object property.

Make the ES module version of the loose parser actually work.

New features

Implement the template literal revision proposal for ES9.

5.0.3 (2017-04-01)

Bug fixes

5.0.2 (2017-03-30)

Bug fixes

A binary operator after a parenthesized arrow expression is no longer incorrectly treated as an error.

5.0.0 (2017-03-28)

Bug fixes

Raise an error for duplicated lexical bindings.

Fix spurious error when an assignement expression occurred after a spread expression.

Accept regular expressions after of (in for/of), yield (in a generator), and braced arrow functions.

4.0.11 (2017-02-07)

Bug fixes

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

4.0.10 (2017-02-07)

Check for use of 'use strict' directives in non-simple parameter functions, even when already in strict mode.

4.0.9 (2017-02-06)

Bug fixes

Fix incorrect error raised for parenthesized simple assignment targets, so that (x) = 1 parses again.

4.0.8 (2017-02-03)

Bug fixes

Solve spurious parenthesized pattern errors by temporarily erring on the side of accepting programs that our delayed errors don't handle correctly yet.

4.0.7 (2017-02-02)

Bug fixes

Accept invalidly rejected code like (x).y = 2 again.

Don't raise an error when a function inside strict code has a non-simple parameter list.

4.0.6 (2017-02-02)

Bug fixes

Fix exponential behavior (manifesting itself as a complete hang for even relatively small source files) introduced by the new 'use strict' check.

4.0.5 (2017-02-02)

Bug fixes

Disallow parenthesized pattern expressions.

Allow keywords as export names.

Don't allow the async keyword to be parenthesized.

Properly raise an error when a keyword contains a character escape.

Allow "use strict" to appear after other string literal expressions.

Disallow labeled declarations.

4.0.4 (2016-12-19)

Bug fixes

Fix issue with loading acorn_loose.js with an AMD loader.

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

4.0.3 (2016-08-16)

Bug fixes

Allow regular function declarations inside single-statement if branches in loose mode. Forbid them entirely in strict mode.

Properly parse properties named async in ES2017 mode.

Fix bug where reserved words were broken in ES2017 mode.

4.0.2 (2016-08-11)

Bug fixes

Don't ignore period or 'e' characters after octal numbers.

Fix broken parsing for call expressions in default parameter values of arrow functions.

4.0.1 (2016-08-08)

Bug fixes

Fix false positives in duplicated export name errors.

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

Implement check against complex argument lists in functions that enable strict mode in ES7.

3.2.0 (2016-06-07)

Bug fixes

Improve handling of lack of unicode regexp support in host environment.

Properly reject shorthand properties whose name is a keyword.

Don't crash when the loose parser is called without options object.

New features

Visitors created with visit.make now have their base as prototype, rather than copying properties into a fresh object.

Make it possible to use visit.ancestor with a walk state.

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.

New features

Fixes

Allow update expressions as left-hand-side of the ES7 exponential operator.

3.0.2 (2016-02-10)

Fixes

Fix bug that accidentally made undefined a reserved word when parsing ES7.

3.0.0 (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.

2.7.0 (2016-01-04)

Fixes

Stop allowing rest parameters in setters.

Make sure the loose parser always attaches a local property to ImportNamespaceSpecifier nodes.

Disallow y rexexp flag in ES5.

Disallow \00 and \000 escapes in strict mode.

Raise an error when an import name is a reserved word.
