From the GitHub release page:
This is the second alpha release of CircuitPython 6.0.0. It is alpha because we are planning one more API change to
ulab. It is relatively stable.
Feature-wise, 6.x 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.
Download from circuitpython.org
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.
Try the latest version of the Mu editor for creating and editing your CircuitPython programs and for easy access to the CircuitPython serial connection (the REPL).

displayiooperations that read from an SD card (e.g.,
OnDiskBitmap) will interfere with other SD card operations and can cause lockup. To work around this problem, do not read or write files on the SD while the display is updating, and vice versa.
