git-notify
Communicate important updates to your team via git commit messages
...In a small team, a Slack message works okay, but in larger teams and distributed organizations (such as open-source projects), reaching everyone can be a pain. git-notify allows you to embed announcements into your git commit messages. And display them to another developer on a machine, far far away. Just add "git-notify:" to your git commit message, and anything that follows will be displayed when another developer pulls that commit, or switches from a branch that does not contain that commit to one that does. If you're using a merge or squash commit strategy on GitHub, you can also add them to the extended commit message when landing a PR. git-notify will display a message for every "git-notify:" prefix it finds in the commit log that was just pulled/merged/rebased/checked out.
