0.4.0

  • Greenlet has an instance dictionary now, which means it can be used for implementing greenlet local storage, etc. However, this might introduce incompatibility if subclasses have __dict__ in their __slots__. Classes like that will fail, because greenlet already has __dict__ out of the box.
