On October 2, 2023, a major update was released for Python 3.12.0, which contains many new features and optimizations. Let's take a look at the main changes.
New Features:
- More flexible f-string parsing, allowing many things previously disallowed (PEP 701).
- Support for the buffer protocol in Python code (PEP 688).
- A new debugging/profiling API (PEP 669).
- Support for isolated subinterpreters with separate Global Interpreter Locks (PEP 684).
- Even more improved error messages. More exceptions potentially caused by typos now make suggestions to the user.
- Support for the Linux perf profiler to report Python function names in traces.
- Many large and small performance improvements (like PEP 709 and support for the BOLT binary optimizer), delivering an estimated 5% overall performance improvement.
