Generate wip changelogs

[heddendorp]

I'd love to have a way to generate a master/upcoming chnages changelog, so even if there was no release the changelog would show the data from issues snce the latest release

This is a great idea! A related conversation, which I unfortunately noticed long after the actual conversation, was had in #83, a PR for allowing pre-releases, some time ago.

Anyway, if I understood correctly, this could be a sort of precursor to that. Do you want/have time to take a shot at a PR?

I hacked up a version for me https://gist.github.com/Isigiel/4c621cff3f58fd1983a6877b51bf0359
the major downside is that the commit fails if it's run without any new changelog items. also this version uses os specific line endings
So @Tapppi if that's suited for you you can freely take the code, or I could maybe on the weekend send in a more refined pull request

@Isigiel Just to clarify, you have also modified conventional-changelog to return the title as Unreleased vX.Y.Z? PR's would be greatly appreciated, otherwise we'll get to it once we can! 😅

Hi – I think the --dry-run option would (now) be an option for you – see example output below.

$ npx standard-version --dry-run
npx: installed 207 in 7.154s
