Exciting news this week as CircuitPython released its 1.0.0 stable release!  This release follows a small set of earlier release candidates that fixed small issues, updated documentation and stabilized the API’s for accessing hardware from CircuitPython.  Check out the releases page on GitHub for the latest CircuitPython binaries for boards like the Adafruit Feather & Metro M0 line, Circuit Playground Express, and more.  For the M0 & Circuit Playground Express boards in particular you can follow these steps to load CircuitPython firmware on your board too.

This is the first stable release of CircuitPython! That means we believe everything works well and that the APIs are largely fixed. This release was made from the stable branch. The master branch is now working towards the 2.0.0 release.
