tl;dr:"Python 3.11 was released a few days ago and as usual, it comes with more than a few new features that make it ever more interesting, from exception groups and fine-grained error locations and tracebacks to TOML parsing support in the standard library and of course the much awaited speedup as part of the faster CPython project. CPython 3.11 is 25% faster than CPython 3.10 on average according to benchmarks with pyperformance."
