Syncing pull requests with rebase

Now you can select the option to rebase your pull request upon initiating a sync, whereas before you could only sync your pull request using a merge commit. For more information on Git rebase, check out the Git rebase tutorial.

We will begin the rollout to 25% of our users on Monday, September 23, 50% of our users on the following day, September 24, and then to 100% of users on September 25.
