For the first time, developers will be able to use GitHub for their private projects with up to three collaborators per repository for free. According to the company, there are many who want to use private repos to apply for a job, work on a side project, or test something out in private before releasing it publicly. Now, those scenarios and many more are possible on GitHub at zero cost. "Public repositories are still free (of course -- no changes there) and include unlimited collaborators."
GitHub Enterprise is the new unified product for Enterprise Cloud and Enterprise Server. Users who want the flexibility for using GitHub in a cloud or self-hosted configuration, now have the option to access both at one per-seat price. Using GitHub Connect's hybrid option, developers can work seamlessly across both environments.

The official blog also indicates,

"GitHub Pro (formerly GitHub Developer) and GitHub Team are also available for developers and teams who need professional coding and collaboration features. And of course, open source contributors will still have everything they need to collaborate on public repositories, including our free version of GitHub Team." 
While developers have access to use GitHub for free for public and open source projects, paid plans allow working together across unlimited private repositories. The company's pricing page lists plans ranging from free to $21 per user per month, while GitHub Enterprise is available in a 45-day free trial.
