> Ok, but how do you know that a change (possibly a bugfix) in your code will break something (maybe a weird, broken thing) that I depend on?

This isn't rocket science.

Fix bug that doesn't change behavior nor the interface? Bump patch number.

Add feature/extend interface? Bump minor version.

Otherwise, bump major version.

That's pretty much it.

For a detailed definition:

https://semver.org/spec/v1.0.0.html

The point of semver is that it's a kind of contract where you implicitly summarize the nature of the changes you introduce in a release in its version number. You provide contextual hints through the version number.

How would you fix a bug without changing behavior? “Incorrect behavior” is the definition of a bug.
