Adafruit has today announced the availability of its
new CircuitPython 3.0.0 Alpha 6 release which was made available and offers the
latest major revision of CircuitPython and features new support for the SAMD51
(aka M4) and preliminary support for the nRF52 BLE chipset. The CircuitPython
3.0.0 also features enhanced memory utilisation allowing users to load more
into the same amount of space.
The latest CircuitPython 3 release has now been made
available via the official Github page. But remember This is an alpha release
of 3.0.0. Alpha releases do not have the complete API from 2.x and are only
meant for testing. (Beta release will have the full API but still need work.)
if you are just starting out using CircuitPython use the latest stable release
which is currently CircuitPython 2.2.4 which was launched last month on March
7th, 2018.
