This is a major upgrade, advancing seven versions from Python 3.7 to 3.14.3. This update introduces significant breaking changes, most notably the removal of numerous standard library modules, the deletion of distutils, and the end of Python 2 compatibility layers. Thorough testing and code modifications are required.

Key Breaking Changes:

• Module Removals (PEP 594): Python 3.11 deprecated many old standard library modules (often called "dead batteries"), and Python 3.13 removed them entirely. [5, 16] This includes modules like aifc, cgi, cgitb, crypt, imghdr, mailcap, nntplib, pipes, telnetlib, and uu. Any code relying on these modules will fail.
• Removal of distutils: The distutils package was deprecated and fully removed in Python 3.12. [15] Build scripts and package installers relying on distutils must be migrated to setuptools.
• End of Python 2 Compatibility Layers: Python 3.9 was the final version to support certain Python 2 compatibility features. [13] Starting in Python 3.10, aliases for Abstract Base Classes in the collections module (e.g., using collections.Mapping instead of collections.abc.Mapping) are removed. [13, 14]
• New Typing Syntax: Newer Python versions introduce modern typing syntax. For example, Python 3.10 introduced the | union operator (e.g., int | float instead of typing.Union[int, float]), and Python 3.9 allowed the use of built-in collection types like list and dict as generics instead of typing.List and typing.Dict.
