git-pr-release 
Creates a "release pull request", whose body consists of features list or
pull requests that are to be released into production. It's especially useful for QA and
pre-release checks. git-pr-release automatically collect pull requests
merged into master branch and generates the content of the release
pull request.
Suitable for branching strategy like below (similar to git-flow):
- Feature branches are first merged into "staging" (or release, development) branch.
- Then the staging branch is merged into "production" branch, which is for production release.
Configuration

in file .git-pr-release (instead of .git/config or ~/.gitconfig) to share project-wise configuration to other
collaborators.
