A few years ago I started working on an open-source project, but things continued and now--years later--I currently maintain my own branch of the project. The project currently resides on GitHub.
The project has the boilerplate MIT license and copyright on every file in the project. I have simply been copy/pasting this into every new file, and have never changed it anywhere.
So my questions are:
- How should I include myself in the copyright (and do I need to)?
- Can I update all the current files' copyright to reflect modifications over the last X years?
