This PowerShell script generates release notes for Octopus Deploy that contain the GitHub commits and JIRA issues from the current build to the latest production release. It will also create the Octopus release based on the TeamCity build number.
#
# Assumptions
#
# 1. If you have a Octopus release deployed, say 1.0.0.73, there is a git
# tag set for that commit in GitHub that is "v1.0.0.73".
#
# 2. You have TeamCity label each successful build in GitHub with the format
# "v{build number}. Sidenote: it appears that TeamCity only labels the
# default branch, but not feature branches.
