Missing changelogs and releases

[axelpale]

Hi, I am an email-validator user and a developer who wants to keep his apps dependencies up to date. I have to migrate my email-validator from 1.2.3 to 2.0.4. I would like to know what where the breaking changes. I would like to do that without diving into the commits. That would be hard detective work and lots of slow read.

Shall I point to a good example of a release: https://github.com/socketio/socket.io/releases/tag/4.0.0

Update: found CHANGELOG.md but it did not contain any instructions for v1 to v2 migration.
