This is the first alpha release of CircuitPython 6.0.0. It is a renumbered version of 5.4.0 because i2cslave module and class have been renamed to i2cperipheral. It is alpha because we may remove or rename additional APIs. It is relatively stable.
Feature-wise, this stable release adds basic lower power support when in time.sleep() and initial ESP32-S2 support. The lower power work changed time keeping and may have introduced bugs. Please use 5.3.0 if you need a stable version of CircuitPython.
Downloads are available from circuitpython.org! The site makes it easy to select the correct file and language for your board. The downloads page is here. Downloads are no longer available from the GitHub release pages because of the large number of files for each release.
