Python 3.12.0 Release Candidate 3 now available #Python @ThePSF
Python 3.12 is at release candidate 3, now out for community review (it will be the last release preview for 3.12).
New features
More flexible f-string parsing, allowing many things previously disallowed (PEP 701).
Support for the buffer protocol in Python code (PEP 688).
A new debugging/profiling API (PEP 669).
Support for isolated subinterpreters with separate Global Interpreter Locks (PEP 684).
Even more improved error messages. More exceptions potentially caused by typos now make suggestions to the user.
Support for the Linux perf profiler to report Python function names in traces.
Many large and small performance improvements (like PEP 709 and support for the BOLT binary optimizer), delivering an estimated 5% overall performance improvement.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
