## 3.0.4 (2016-02-25) ### 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. ## 2.6.4 (2015-11-12) ### Fixes Fix crash in loose parser when parsing invalid object pattern. ### New features Support plugins in the loose parser. ## 2.6.2 (2015-11-10) ### Fixes Don't crash when no options object is passed. ## 2.6.0 (2015-11-09) ### Fixes Add `await` as a reserved word in module sources. Disallow `yield` in a parameter default value for a generator. Forbid using a comma after a rest pattern in an array destructuring. ### New features Support parsing stdin in command-line tool. ## 2.5.2 (2015-10-27) ### Fixes Fix bug where the walker walked an exported `let` statement as an expression. ## 2.5.0 (2015-10-27) ### Fixes Fix tokenizer support in the command-line tool. In the loose parser, don't allow non-string-literals as import sources. Stop allowing `new.target` outside of functions. Remove legacy `guard` and `guardedHandler` properties from try nodes. Stop allowing multiple `__proto__` properties on an object literal in strict mode. Don't allow rest parameters to be non-identifier patterns. Check for duplicate paramter names in arrow functions.
