Downgrade addon's build?

I ran the build release command on my addon and once the zip file was created (let's say it's v2) I bumped up the version (so now it's v3).

Then I made some changes to some files (controllers, routes, templates etc). But now I realize I want to undo all those changes.

So is there a way to have the source code go back to the v2 version after which I can bump it again and start making fresh changes?
