CircuitPython 5.0.0-beta.5

This is the latest unstable release of CircuitPython that will work with the ARAMCON Badge 2019.

Unstable builds have the latest features but are more likely to have critical bugs.

Release Notes for 5.0.0-beta.5

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.

Past Releases

All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
