## v2.0.0

- Full scratch of internal implementation
  - Rendering is strongly optimized
     - Static analyzer is introduced
     - Built with C extension for runtime rendering
     - Optimized compilation for 5 types of attributes
  - Compilation became faster too
  - Many rendering incompatibilities are resolved
  - Object reference support
  - Breaking changes:
     - Replaced parser with original Haml's one
         - Incompatible parsing error will never happen, but we can no longer parse attributes with Ripper
     - Unified behavior for both static and dynamic attributes, see [5 types of attributes](REFERENCE.md#5-types-of-attributes)
         - Though inconsistent behavior is removed, we can no longer rely on completely-Haml-compatible behavior of static attributes and pass haml-spec
     - Added :escape\_attrs option
         - You should specify HTML-escaping availability for script and attrs separately.
