I read Git commit history regularly, like this aliased command: git log --color --graph --oneline --decorate

Or this one for a Markdown list: git log --since="last version" --pretty=format:'- %s'

It helps me to:

- See what feature areas have been recently worked on

- Check if commits have been pushed to remotes

- Gather all commit messages since last version, and copy & paste (and edit) into changelog

Occasionally, I need to go back through the history and find a specific change - I typically just grep the commit messages for a word or phrase.

I also read commit messages of forked repos, to keep informed of what's happening upstream.
