PropEr version 1.4.0 comes with the following release highlights:
- Parallel execution of tests (thanks to @pablocostass)
- An implementation of Targeted Stateful Property-Based Testing (thanks to @xspirus)
- A generator of Erlang programs in abstract code format (thanks to @uabboli)
- Support for Erlang/OTP versions 20.0 to 24.0
In addition, there have been various code improvements and bug fixes (see THANKS file).
A notable backwards incompatible change is the new, cleaner interface for targeted property-based testing.
