Extract description from CHANGELOG file with keep a changelog standards

Summary

Currently it is possible read description from a file, but in many cases the CHANGELOG file contains all the releases history. It would be great if this tool could parse the CHANGELOG file and extracts just the piece of changelog corresponding the current release tag.

In order to achieve that we need a changelog standard/convention -> keep a changelog. With this convention it should be possible to parse and extract the right piece of information from changelog file.

Already exists a tool that does this -> release-it/changelog.
