View commit history

I need the commit history for the auth-service for the past month. Show all commits on main from 2026-06-01 to 2026-07-01, include author, date, short message, and the files each commit touched. Export that as a plain text list so I can paste it into the release notes.

Before I send the commit history to QA, make it easy to scan: pull the commits on main since 2026-06-01, group them by feature (login, token refresh, rate limit), highlight commits that changed public APIs or migrations, and flag any commits without accompanying PRs or that lack test changes.

QA says token expiry behavior changed last week but I can’t identify which commit caused it. I have the date range and the auth-service repo. What’s the quickest way to pinpoint the commit that altered token expiry, what grep or blame steps should I run, and who on the team is the best person to ask if commit messages are sparse?

We spend hours tracing behavioral changes because commits are poorly labeled and PRs are inconsistent. Which three habits will most reduce investigation time across repositories — for example, standardized commit prefixes, mandatory PR checklists, or automated changelog generation — and which one habit will give the biggest immediate payoff for our small team?
