[Twisted-Python] Pip's Twisted 19.7.0 package is offered to upgrade my v19.2.1...

[Ant]

Hello.

I cannot figure out how to report this minor bug of a minor upgrade 
issue (https://github.com/twisted/twisted didn't have an issues 
section) that I noticed since last week:

$ pip list --outdated                       DEPRECATION: Python 3.4 support has been deprecated. pip 19.1 will be the last one supporting it. Please upgrade your Python as Python 3.4 won't be maintained after March 2019 (cf PEP 429).
Package Version Latest Type

That v19.7.0 shouldn't even be offered for my outdated setups. :(

Thank you for reading and hopefully answering soon. :)
