  • Issues (closed issues w/o any labels)
  • Merged pull-requests (all merged pull-requests)
  • Bug-fixes (by label bug in issue)
  • Enhancements (by label enhancement in issue)
  • Excluding "questions" from changelog (issues marked as question labels)
• Ability to manually specify in which version issue was fixed (in case, when closed date is not match) by setting milestone of issue the same name as tag of required version
• Ability to exclude some issues from changelog (by labels)

Usage:

It's really simple:

• If your git remote origin refer to your GitHub repo, then just go to your project folder and run:

    github_changelog_generator
  

• or from anywhere:

GitHub token

Since GitHub allow to make only 50 requests without authentication it's recommended to run this script with token

You can easily generate it here.

And:

• Run with key -t [your-16-digit-token]

• Or set environment variable CHANGELOG_GITHUB_TOKEN and specify there your token.

  i.e. add to your ~/.bash_profile or ~/.zshrc or any other place to load ENV variables string :

    export CHANGELOG_GITHUB_TOKEN="your-40-digit-github-token"
  

So, if you got error like this:

! /Library/Ruby/Gems/2.0.0/gems/github_api-0.12.2/lib/github_api/response/raise_error.rb:14:in `on_complete'

It's time to create this token or wait for 1 hour before GitHub reset the counter for your IP.
