Please note that this framework supports older OS X versions down to 10.10. When changing the code, be careful not to call any API functions not available in 10.10 or call them conditionally, only where supported.
Please use descriptive commit message. As an example, Bug fix commit message doesn’t say much, while Fix a memory-management bug in formatting code works much better. A nice detailed article about writing commit messages is also available.
Use git tags.
Make sure to update the changelog!
