We recently changed the Watcher behavior on GitHub. What used to be known as "Watching" is now "Starring". Starring is basically a way to bookmark interesting repositories. Watching is a way to indicate that you want to receive email or web notifications on a Repository.
This works well on GitHub.com, but poses a problem for the GitHub API. How do we change this in a way that developers can gracefully upgrade their applications? We’re currently looking at rolling out the changes in three phases over an extended period of time.
Today we are announcing the first steps towards separate "Watching" and "Starring" APIs.
New API Endpoints
There are some new Star endpoints for the API. Don't fret, your old Watch endpoints are still working. The new Watch endpoints are available too. However, the paths use the internal "subscriber" and "subscriptions" terms so they don't clash with legacy apps using the Watch endpoints.
We've detailed the slow transition of the Star and Watch endpoints, which will help provide a smooth upgrade path.
The API Developer site now has a Changes blog for upcoming breaking changes. It also has a low volume Atom feed for subscriptions. If you are developing tools on top of the GitHub API, you should keep up through this blog, or the @GitHubAPI Twitter account.
