[feature request] display the previous version

[vdegenne]

When upgrading (or downgrading, either way) NodeJS through nvm it would be nice to see the from version, e.g.

$ nvm i stable

Current version: v22.0.0 (npm v9.0.0)
Now using node v23.4.0 (npm v10.9.2)

(It's just a small satisfaction to see if anything got updated)

Usually i think people put the node version in their prompt, so they can always see that change.

What do you mean by "prompt" ?

You mean people type node --version before running nvm?

Not so sure about that, or if they do, this addition is there to help them (that is the reason.)
Or sometimes people forget to check their version and update using nvim i stable but after the update have no clue what version they were on.

no, i mean like the $ that displays before you type your command - that's a shell prompt. mine has the current git branch, current nvm node version, and the computer name.

ah shell prompt. That's oddly specific, I tend to keep it simple, especially because I don't use terminal just to do nodejs stuff. Also I am curious how many people actually display their nodejs version in their prompt.

Anyways that was just a suggestion, I can personally live without, but for a versioning manager I feel like that's the least that should be display in the output.
