`cvxpy` cannot be imported in python 3.12

[jlopezpena]

Is there a plan to make a new release soon? Even if it can be installed with python 3.12, version 1.4.2 cannot be used there due to syntax errors in some docstrings. This error shows up when pytest tries to collect tests in our codebase:

I can see that the issue is already fixed in main, but no release has been made since. Could a patch version get release to get around the issue?

A patch is imminent (next few days).

The latest release (https://pypi.org/project/cvxpy/1.4.3/) includes the fix (#2351).
