Let’s suppose there’s a company abc that makes a library abc.

So ive been thinking about what the conditions are for when an application would break functionality. Say you’re designing an application which uses a specific version of Python. Youre application uses standard library modules and non-standard library modules or those developed by Python Designers. Your application would not break functionality since those versions of standard library and non-standard library would be installed on your computer and isolated from a remote repository. But only when you update the version of Python, standard library modules and Python Designer modules would your code possibly break functionality. Another case would be where you transfer your application to someone else’s computer, they have mismatched Python and modules version and proceed to update their Python version, library version and designer versions to the newest release. Then the application could break functionality. Is this correct? Are there another other instance where an application could break functionality. Assuming the application is free of design flaws.

Whenever I get ready to release a new version of a pypi package, I do the following:
