The version number will be incremented based on [semantic versioning](http://semver.org/) as features and bug fixes are added. - -The immediate plans are: - -1. Move away from giant files and move towards small, modular files that are easier to manage. -1. Move towards CommonJS for all files and use browserify to create browser bundles. -1. Support ECMAScript version filtering, allowing users to specify which version the parser should work in (similar to Acorn's `ecmaVersion` property). -1. Add tests to track comment attachment. -1. Add well-thought-out features that are useful for tools developers. -1. Add full support for ECMAScript 6. -1. Add optional parsing of JSX. - ## Esprima Compatibility Going Forward -The primary goal is to produce the exact same AST structure as Esprima and Acorn, and that takes precedence over anything else.

Releases will happen periodically as changes are made and incremental releases will be made towards larger goals. For instance, we will not have one big release for ECMAScript 6 support. Instead, we will implement ECMAScript 6, piece-by-piece, hiding those pieces behind an `ecmaFeatures` property that allows you to opt-in to use those features. - ## Contributing Issues and pull requests will be triaged and responded to as quickly as possible.
