With pull requests, developers can tell others about the changes they're pushing to the code. And you can now use pull requests to quickly add entries to your changelog.
Once a pull request is closed (and, probably, merged), simply select it in GitInLog and start a new entry. The pull request description will automatically be there for your to further personalized it and publish it. This will, in turn, add all associated commits to your entry and keep your project in track with all pending changes.
