Expanding context in diffs

Whether it’s reviewing community changes to an Open Source project, or
using GitHub Flow on
a private project, we all spend a lot of time looking at diffs.
But to really understand a code change, we sometimes need to see more than just
the default three lines of context.

Today we’re excited to announce a new feature that makes this possible.
Using the new unfold button in the gutter of a diff, you can reveal
additional lines of context with a click.

You can keep clicking unfold until you’ve revealed the whole file, and the feature is
available anywhere we render diffs.

Happy code reviewing!
