reg tempalate based configration

Is any place/link to check all configuration file formats, parameters, etc. I would like to monitor if any changes/addition in parameters if any new release. In this way, I may able to update/ correct my system if any bug.

In my file -

httpdWorkers 1 ( not present and many more parameters are missing )
module cache is also defined in the main configuration file which is discontinued as per my knowledge

Is this link is updated or any other link where I can check what new?

Attaching my file. Please help .. how to sync/update this file if any more addition in release?
Please guide.
