I understand that a new version of the Arduino software will have live debugging with STEP,WATCH etc.
When is this scheduled to be released?
Is there a link to the Arduino software future road map?
don't expect it for Uno/Nano/Mini. ATmega328p has poor debug support.
maybe for Nano Every and Uno WiFi. the 4809 has good debug support.
but I guess it will be only for ARM MCUs.
I can step debug Arduino sketches on SAMD with Sloeber Eclipse plugin and external programmer/debugger.

From When the debugger will be released? · Issue #178 · arduino/arduino-pro-ide · GitHub
probably beginning / mid February

There is no public road map. If you follow all the Arduino repositories you are interested in, subscribe to the Arduino developers mailing list, subscribe to the Arduino Blog's RSS feed, watch the videos of the speeches given by Arduino people at the various events they attend (e.g., Maker Faires, CES, Arduino Day), and read/watch any interviews they give, you'll pick up the occasional hint of where things are going. But don't put too much stock in them because "The best-laid plans of mice and men often go awry."
