+## Version 0.12.0
+- Add BindReturn to Property CE ([#364][364], [@TysonMN][TysonMN])
+  - A breaking change.  Previously, returning a `bool` from a `property` CE caused the CE to have return type `Property<unit>`.  Now this results in a return type of `Property<bool>`.  The previous behavior can now be expressed by piping the `Property<bool>` instance into `Property.failOnFalse`.

 ## Version 0.11.0 (2021-09-22)
