From the GitHub release page:
This is the second beta release of CircuitPython 6.0.0. It is relatively stable overall. See
port status
below for more stability detail. This release includes a newcanio
API, support for the 128×64 OLED and many fixes. Please use 5.3.x 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.
Installation
To install follow the instructions in our new Welcome to CircuitPython! guide. To install the latest libraries, see this page in that guide.
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).
Port status
CircuitPython has a number of "ports" that are the core implementation for a variety of microcontroller families. Stability varies on a per-port basis. As of this release,
atmel-samd
,nrf
, andstm
for the F4 family are stable.cxd56
,esp32s2
, andstm
for other chip families are being actively improved but may be missing functionality and have bugs.litex
andmimxrt10xx
are in an alpha state and will have bugs and missing functionality.New features and improvements since 6.0.0 Beta 0
API changes and additions
- Add
canio
API for communicating over CAN BUS #3425 #3466 Thanks @dhalbert, @jepler and @siddacious- The default speed of busio.I2C and board.I2C is now 100khz, not 400khz as before. Use
busio.I2C
to set the speed explicitly. #3471 Thanks @caternuson, @ladyada, @hierophect and @tannewt- Add
SH1107_addressing
kwarg todisplayio.Display
to support the SH1107 used in the 128×64 OLED with the new library. #3450 Thanks @mdroberts1243 and @jeplerFixes and enhancements
- Fix memory corruption with sharp display. #3497 Thanks @jepler
- Fix hang when using OnDiskBitmap with a file on an SDCard. #3449 Thanks to @foamyguy and @jepler
- Update TinyUSB to get MIDI SysEx fix. #3473 Thanks @mzero and @tannewt
- Pins in
board
now print with their board name. #3470 Thanks @askpatrickwBoard- and port-specific changes
- ESP32-S2:
- Fix
digitalio
on pins that don’t default to GPIO and fix reading back output value. #3495 Thanks @tannewt- Fix connecting to wifi without scanning first. #3489 Thanks @astrobokonon
- Fix SPI
write_value
support so SD cards work. #3448 Thanks @hierophect, @jepler and @emard- Fix
time.time
andtime.localtime
. #3451 Thanks @microdev1, @hierophect, @askpatrickw and @anecdata- Build and release UF2 files #3475 Thanks @tannewt

no longer replaced in QSTRs. #3456 Thanks to @jeplerFull commit log is here.
Breaking changes since 5.x
i2cslave
is nowi2cperipheral
and the class in it is changed as well.- The
stop
kwarg has been removed fromI2C.writeto()
. If no stop is desired, then usewriteto_then_readfrom
.- The default speed of busio.I2C and board.I2C is now 100khz, not 400khz as before. Use
busio.I2C
to set the speed explicitly. #3471 Thanks @caternuson, @ladyada, @hierophect and @tannewtNew boards since 6.0.0 Beta 0
- Adafruit QT Py Haxpress #3476 Thanks @jepler and @ladyada
- Adafruit Metro ESP32S2 #3495 Thanks @tannewt and @ladyada

Documentation
Documentation is available in readthedocs.io.
This release is based on MicroPython 1.9.4 @25ae98f. Support upstream MicroPython by purchasing a PyBoard (from Adafruit here) or sponsoring MicroPython on GitHub.
Translations
One important feature of CircuitPython is translated control and error messages. With the help of fellow open source project Weblate, we’re making it even easier to add or improve translations. Sign in with an existing account such as Github, Google or Facebook and start contributing through a simple web interface. No forks or pull requests needed!
Troubleshooting
Check out this guide for info on common problems with CircuitPython. If you are still having issues, then post to the Adafruit Support Forums and join Discord.
Assets
Builds are no longer stored as assets on this release page, because there are too many of them. Please see the Download from circuitpython.org section above.
