Support outputting a changelog in reStructuredText

Description

As the title states, it would be convenient for use with sphinx documentation to be able to output the changelog in rst format.

Possible Solution

This seems like it should be a configuration option versus a commandline option.

That makes a lot of sense and would simplify things a lot. Either generate all or latest, right?. If you need specific range you can use cz changelog 0.2.0..0.4.0 and that would cover all the cases. Is a trade-off over more manual work (sometimes), vs making it more flexible to support other formats.

One good thing about the detection of the title is that you can have a bunch of text before the changelog (like the recommendation of keepachangelog before start listing the changes). How could we achieve that?

One solution could be to only generate the changelog for the latest release by default. Then, if someone wants to generate a changelog for all releases, have that be a command option. Users should only ever be generating a changelog for more than the most recent version of their project once, at the time of adoption of this tool.

If the user only wanted a changelog for the last X number of versions, then it would be an easy cut/paste job from the command generated changelog. Again, this scenario should only ever happen once in a project’s lifetime, so not a big deal.

It doesn’t seem you’d need to be inspecting any changelog files with this all or one generation approach, and then could theoretically support any number of file types, given the changelog output itself is configurable.
