generate changelog for a single tag

Description

Hi everyone, thanks for your work. I’d like to generate my changelog with commitzen in ci, and store them in github releases instead of a whole changelog.md in my source files.

But It looks impossible now, I can only generate the full changelog, or split them manually from a specific tag.

Possible Solution

add a filter arguments to filter single tag like:

cz changelog --tag v0.0.5

additional information

There already has been a --start-rev argument that may help with this. But I think it would be better to have a way select to just a single tag for ci or other things to simplify the workflow.

This is inspired by https://github.com/git-chglog/git-chglog#cli-usag

Now I’m doing it with git-chglog "$TAG" > chglog.md and gh release create "$TAG" -F chglog.md

git-chglog has a syntax like 0.0.3..0.0.5 to select versions from 0.0.3 to 0.0.5

Hope this information could help https://github.com/commitizen-tools/commitizen/issues/225

Even through I don’t like this syntax

This could be interesting. What if we used version instead of tag? Would that be okay? Of course the tag would be calculated based on the tag_format.

This way you could do:

cz changelog --version $(cz version --project)
