Config-help: Previous version in PR title and commit message

[augi]

What would you like Renovate to be able to do?
It would be great if the title of a newly created PR and commit message contained also information about the previous version. It's useful esp. in commit message because then it is obvious from changelog if it's a major version update or just a patch.

commitMessage and it’s children are templates that can be modified. I think if you search this repo there might be an example or two already. See also the docs for “templates”

Thank you for quick response! ❤️ So what I need is to change the commitMessageExtra configuration, for all the repositories (I'm using renovate as Docker image, for self-hosted GitHub Enterprise).

So should I set COMMIT_MESSAGE_EXTRA environment variable of that Docker container to something like "from {{{fromVersion}} to {{{toVersion}}}"?

So I have actually two questions:

1. Is it possible to set COMMIT_MESSAGE_EXTRA environment variable when executing the renovate Docker image?
2. Is fromVersion valid _variable_ to use?

Thank you! 🙏

FYI, you can already tell which are major or non-major updates by looking at the commit message and PR title.

Minor ones look like this: "Update foo to v4.1.0"
Major ones look like this: "Update foo to v4"

Description of template variables is here: https://docs.renovatebot.com/templates/

Setting COMMIT_MESSAGE_EXTRA probably isn't enough because this Docker default will override it: https://github.com/renovatebot/renovate/blob/e411a70e2d222a05e8338cbdff3270ca54e48c8e/lib/config/definitions.ts#L1462-L1463

You should either:

• Have a config.js or config.json within your bot container (e.g. mapped using volumes), or
• Use your own preset config that each of your renovate.json repository configs should extend

Both of the above would mean that you could configure once and then get the same setting applied throughout.
