Ever run npm update or composer update and wonder what actually changed? Sure, you see package names scroll by, but what releases did you skip? What features or fixes did you get?
Whatsdiff answers that question. It's a CLI tool that compares your dependency files between commits and shows you exactly what changed—with release counts, version ranges, and even full changelogs.
I made this tool for myself. After a year of using it, I decided it needed some attention. v2 is here with a website and documentation.
