May 21, 2024 - Python 3.12 introduces major improvements including a refined type parameter syntax, enhanced error messages, and module enhancements.

May 10, 2024 - Low overhead debugging features make using a debugger by default for all development tasks a no-brainer. There are also new typing features, performance improvements, and standard library APIs.

October 3, 2023 - Python 3.12 also brings a new optimization for list/dict/set comprehensions. Comprehensions are now inlined, which means that they are faster. Instead of creating a new single-use function for each execution, comprehensions are now inlined.
