About Python 3.11
Python 3.11 was the 'performance release,' delivering 10-60% speedups over 3.10 through the Faster CPython project. It also introduced exception groups and fine-grained error locations.
Key Changes in Python 3.11
- ●10-60% faster than Python 3.10 (average 25% on benchmarks)
- ●Fine-grained error locations in tracebacks pointing to exact expression
- ●Exception groups and
except*syntax for handling multiple errors - ●tomllib added to stdlib for reading TOML configuration files
- ●TaskGroup API for structured concurrency with asyncio
Breaking Changes
- ▲Several deprecated modules scheduled for removal issued warnings
- ▲Some rarely-used C API functions removed
- ▲locale.getdefaultlocale() deprecated
Python 3.11 has transitioned into security-only maintenance since April 1, 2024. This means it still receives critical security patches, but no new features, performance improvements, or non-critical bug fixes will be backported. It remains a safe choice for production systems that cannot upgrade immediately, but you should begin planning your migration path.
When you are ready to upgrade, Python 3.14 is the recommended target. Test your application against 3.14 in a staging environment first, paying attention to any deprecated APIs you may be using.
Lifecycle Progress
67% through its lifecycle. 608 days remaining.
