What does “deprecated” mean, here?

These modules provide the capability to use the Changelog as the canonical location of the current version string.

I don't see what you're proposing that would continue to provide that feature.

We can keep these files if you want.

I removed them due to pbr introduction.
PBR automatize:
- changelog generation
- authors file generation
- version number management

deprecated mean that these files are unnecessary since we introduce pbr.

Automates it how? The content of a changelog document is not kept anywhere else.

If you're thinking of the Git commit messages, those are entirely different. Those messages are targeted to people viewing individual commits, like developers working on the project.

A change log document is not mechanically generated from the Git commit messages; it is targeted not to the project developers but to the users. See the https://keepachangelog.com/ site for more explanation.

So I think that removing these modules is not appropriate for this project.
