[$] Free-threaded Python: past, present, and future

Probably the biggest change for Python over the last five years or so isthe advent of the "free-threaded" version of the language, which removes theglobal interpreter lock (GIL) and allows multiple threads to run inparallel in the interpreter. At PyConUS 2026, held in Long Beach, California in mid-May, longtime CPythoncore developer (and current steering council member) Thomas Wouters gave atalk about the feature. He looked at the motivation behind the GIL-removalefforts, some history,the current status of the free-threaded interpreter, and provided aprediction on where it all leads.
