According to: https://docs.python.org/dev/whatsnew/3.14.html#id2

Remove the following classes. They were all deprecated since Python 3.8, and have emitted deprecation warnings since Python 3.12:
ast.Bytes
ast.Ellipsis
ast.NameConstant
ast.Num
ast.Str

Use ast.Constant instead. As a consequence of these removals, user-defined visit_Num, visit_Str, visit_Bytes, visit_NameConstant and visit_Ellipsis methods on custom ast.NodeVisitor subclasses will no longer be called when the NodeVisitor subclass is visiting an AST. Define a visit_Constant method instead.

Also, remove the following deprecated properties on ast.Constant, which were present for compatibility with the now-removed AST classes:
ast.Constant.n
ast.Constant.s

Use ast.Constant.value instead.

For all our attempts to build fawltydeps with Python 3.14, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14/package/fawltydeps/

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.14:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14/

Let us know here if you have any questions.

Python 3.14 is planned to be included in Fedora 43.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.14.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.
