A simple plugin that adds a rewrite rule for categories to redirect to the latest post in that category.
Please note the prefix latest/ in the url path.
https://example.org/latest/category/uncategorised redirects to
https://example.org/hello-world/ or https://example.org/?p=123 (depending on permalink settings)
The method is really generic and should work with custom and complex modifications to rewrite rules and categories.
