Missing Changelogs / changelog version retrieval change

[viceice]

Currently renovate can't show changelogs when there are missing versions on the registry which are available on source repo.
This often confuses users and they ask questions why there are no changelogs when the source repo has all versions as releases.

current behavior

So current behavior for changelogs.

1. determine platform from source url.
2. call platform specific change log function.
3. call getReleases with current dependency (uses current datasource)
4. use returned versions to calculate needed change logs (here we stop if there are missing versions)
5. fetch changelogs for each version in diff.

I would like to change step 3 to use the platform specific datasource instead ( eg github-tags for GitHub), so we've all required versions to calculate the diff.

sample

An npm package is published as version 1.0.0, 1.0.1 and 1.0.2.
Version 1.0.1 is retracted because of a big bug.
The source is public on GitHub with releases for all versions (using semantic-release).

Renovate opens a PR to update from 1.0.0 to 1.0.2 but doesn't show changelogs because of the missing version on npmjs.

Another sample is k3s. Some users use a custom datasource to only allow the latest stable version, so renovate has only that version. This causes again missing changelogs.

Hi there,

This is intended as a polite, automated request that users avoid @ mentioning repository maintainers like @rarkins or @viceice. Doing so causes annoying mobile notifications and makes it harder to maintain this repository.

We know it might be common elsewhere but we participate in hundreds of discussions a week and would need to turn off GitHub mobile notifications if we were mentioned in every one.

As a general rule, we will read and respond to all discussions in this repository, so there is no need to mention us.

Thanks, the Renovate team

It is probably an edge case, but there hasn't to be tags present to publish new versions.

E.g. people could publish NPM packages versions without using any git tags.

if there are no tags, then we can't show changelogs anyways 🤔
