# This script parses the commit messages between the last 2 git tags
|
|
# if the last commit contains the word "Release", otherwise it shows
|
|
# all the changes between the last tag and HEAD.
|
|
#
|
|
# Commits are grouped in different sections specified in the commit
|
|
# message with the middle-dot character '·'. The section names are
|
|
# arbitrary and we may be careful to use them properly but having
|
|
# in mind that this may change.
|
|
#
|
|
# Commits without any middle·dot in the message are discarted and
|
|
# displayed in the "to review" section.
|
|
#
|
|
# The tool prints Markdown, no plans to support other formats.
|
|
#
|
|
# Usage: sys/release-notes.sh 4.5.1 # from HEAD to 4.5.1
|
|
# $ sys/release-notes.sh 4.5.1 -v # same as above but include untagged commits
|
|
# $ sys/release-notes.sh 4.5.0 4.5.1 # from 4.5.0 to 4.5.1
