New major release 2.0 for Node and ES5 browsers builds on 1.x branch, and adds following features:

• Simplified API.
• Supports ES5 features: getters, setters, generic property descriptors.
  • Internally all properties are defined using ES5 property descriptor API.
• Properties can be defined using the classic object notation, and the list of property descriptors.
• New decorator: dcl.prop().
  • Property descriptors can be specified directly.
  • Getter and setters can be advised as easy as regular methods.
  • Supports “class”-wide defaults for configurable, enumerable, and writable.
• detectProps mode can detect property descriptors in-line without decorators.
• Node’s require() import, and AMD are supported out of box.
• For convenience a version based on browser globals is provided.

At the same time it continues to support successful familiar features:

• Mixin-style OOP.
  • The same trusted and proven C3 MRO linearization algorithm for inherited mixins.
• Full set of AOP.
  • Supports “class” definitions.
  • Regular objects can be advised dynamically.
• The same library of useful advices, bases, and mixins.
• Special debugging facilities, which helped our users with tricky cases.
• Rigorously documented.

Version 1.x is still supported and will continue to be available for legacy browsers.
