Unlimited free private repositories with GitHub Free and a unified business offering with GitHub Enterprise

We’ve made some updates to our offerings for developers and teams:

• GitHub Free gives you unlimited private repositories with up to three collaborators per repository at no cost—and continued access to unlimited public repositories with unlimited collaborators.
• GitHub Developer is now called GitHub Pro. It includes everything in GitHub Free, unlimited collaborators for private repositories, and advanced code review tools for private and public repositories.
• GitHub Enterprise is the new unified product for Enterprise Cloud (formerly GitHub Business Cloud) and Enterprise Server (formerly GitHub Enterprise). Organizations that want the flexibility to use GitHub in a cloud or self-hosted configuration can now access both at one per-seat price.
