Hey! Really cool stuff.
I'm 15, and have been programming since I was 9, but I'm more focused in stuff like Systems Programming and Machine Learning, thus I have not really released anything interesting.
I'm curious too. Semantic diffs maybe? (This change affects control flow, this one doesn't; this change adds complexity, this one removes it.) Something like that would be useful for getting an overview of a project's evolution, instead of highlighting major commits only in terms of lines changed (often just a meaningless refactor.)
