What are some good ways to manage a changelog using Git? [closed]

This was in 2015, but for the sake of future searchers, it’s now possible to generate gorgeous logs with:

git log --oneline --decorate

Or, if you want it even prettier (with color for the terminal):

git log --oneline --decorate --color

Piping that output to ChangeLog is what I currently use in all my projects, and it’s simply amazing.
