新特性和性能改进: 新版本Python带来了许多新特性和性能优化。 建议升级到3.11，因为Python 3.11将得到支持直到2027年10月,为项目提供长期稳定性。

With the introduction of this Faster CPython, Python 3.11 has been speeded up by 10% to 60% from Python 3.10, and it is said that an average speedup of 1.25 times has been achieved.

New versions for the Python 3.10, 3.9 and preview 3.11 series are out today and arrived in spite of numerous hold ups, including a "more complex than expected" code signing certificate renewal.
