effet-0.2.0.0: ChangeLog.md

# Changelog for effet

## 0.1.0.0 (2020-07-17)

* Initial release

## 0.2.0.0 (2020-07-29)

* Lifted the restriction that one handler can exactly handle one effect. Handlers can now handle multiple effects.
* Effects whose definitions refer to other effects (see the RWS effect, for example) are now possible to implement, but only manually for now (i.e., no code generation).
