Sometimes latest versions of the software can cause issues when installed on older devices or devices running an older version of the operating system.

Software makers usually fix these issues but it can take them some time. What you can do in the meantime is to download and install an older version of Python 3.13.6.

What's new in this version:

New features:
- A new and improved interactive interpreter, based on PyPy's, featuring multi-line editing and color support, as well as colorized exception tracebacks
- An experimental free-threaded build mode, which disables the Global Interpreter Lock, allowing threads to run more concurrently. The build mode is available as an experimental feature in the Windows and macOS installers as well.
- A preliminary, experimental JIT, providing the ground work for significant performance improvements.
- The locals() builtin function (and its C equivalent) now has well-defined semantics when mutating the returned mapping, which allows debuggers to operate more consistently.
- A modified version of mimalloc is now included, optional but enabled by default if supported by the platform, and required for the free-threaded build mode.
- Docstrings now have their leading indentation stripped, reducing memory use and the size of .pyc files. (Most tools handling docstrings already strip leading indentation.)
- The dbm module has a new dbm.sqlite3 backend that is used by default when creating new files
- The minimum supported macOS version was changed from 10.9 to 10.13 (High Sierra). Older macOS versions will not be supported going forward.
- WASI is now a Tier 2 supported platform. Emscripten is no longer an officially supported platform (but Pyodide continues to support Emscripten).
- iOS is now a Tier 3 supported platform
- Android is now a Tier 3 supported platform

Typing:
- Support for type defaults in type parameters
- A new type narrowing annotation, typing.TypeIs
- A new annotation for read-only items in TypeDicts
- A new annotation for marking deprecations in the type system

Removals and new deprecations:
- PEP 594 (Removing dead batteries from the standard library) scheduled removals of many deprecated modules: aifc, audioop, chunk, cgi, cgitb, crypt, imghdr, mailcap, msilib, nis, nntplib, ossaudiodev, pipes, sndhdr, spwd, sunau, telnetlib, uu, xdrlib, lib2to3.
- Many other removals of deprecated classes, functions and methods in various standard library modules.
- C API removals and deprecations. (Some removals present in alpha 1 were reverted in alpha 2, as the removals were deemed too disruptive at this time.)
- New deprecations, most of which are scheduled for removal from Python 3.15 or 3.16
