Having such project without maintaining a proper changelog (with at least a note of breaking changes) should be given as an example of how not to publish packages

Don't get me wrong. It's a great little package. Very useful.

But changelogs are there for a reason.

I'm tasked with updating your package (among almost 100 others) in a huge, albeit old, codebase.

Lack of changelog makes my work 10x more inefficient and, ultimately, more expensive.
