Changelog

It finds your latest tag, grabs all commits since then, and writes them into the Unreleased section with linked hashes and one-line summaries. It even tries to detect and link to PRs instead of raw commits when it can. The format is opinionated but sensible: one commit, one line, no fluff. If you maintain a keepachangelog-style file and want to stop manually copy-pasting git log output before every release, this handles the grunt work and lets you focus on editing the lines that actually matter.
