Description
Testing new software builds is one of the easiest ways to get started helping CircuitPython development.
First, find an existing project of yours that works with the latest stable release of CircuitPython. Verify that it all still works as you've set it up.
Next, load a cutting edge build from here.
Now, see if your project works as it did before. If it doesn't work, then look and see if there are open issues related to it. If there is, its likely that it intentionally doesn't work now. If there are no unrelated issues, then please file one!
In the new issue please include a list of all components you are using and the code that you are trying to run on the new version. Someone else will respond with whether its expected or whether it is in fact a bug.
