Getting release notes from Git logs

gitconfig

# drop this into your ./.gitconfig file
# usage
# $ git today
# $ git yesterday
# $ git since 18-11-01
#
# will display a list of formatted commits you can lift to use for release notes

[alias]
	today = log --since=1am --pretty=format:"%C(blue)-\\ %s"
	yesterday = log --since=yesterday --pretty=format:"%C(blue)-\\ %s"	
	since = "!f() { git log --since="$1" --pretty=format:\"%C(blue)- %s\"; }; f"

First two were original aliases I created and the "since" one was added to enable by date -- you can also do:

$ git since yesterday
$ git since today

so you could remove the today and yesterday aliases completely.
