The first year of free-threaded Python

I am a Python user, but far from an expert. Occasionally, I've used 'concurrent.futures' to kick off running some very simple functions, at the same time.

How are 'concurrent.futures' users impacted? What will I need to change moving forward?

It’s going to get faster since threads won’t be locked on GIL. If you’re locking shared objects correctly or not using them all, then you should be good.
