I encounter the word "redux" in "Vector Class Redux" when reading the book "fluent python",

In redux | Definition of redux in English by Oxford Dictionaries

redux adjective [ after noun ] UK ​ /ˈriː.dʌks/ US ​ /ˈriː.dʌks/
​ (often used in the titles of films and video games) brought back:
With "Ashes of Time Redux," Wong has decided to recut and rethink his original material.

The definition helps little to understand it,
google does not helps when searching vector redux

what does it mean here?
