One beautiful thing about open source software: how hundreds of thousands (millions?) of people’s Python apps got faster while they were sound asleep. From 3.11’s release notes:

CPython 3.11 is on average 25% faster than CPython 3.10 when measured with the pyperformance benchmark suite, and compiled with GCC on Ubuntu Linux. Depending on your workload, the speedup could be up to 10-60% faster.
