The Protected Branches API will be graduating from preview mode on September 1, 2017.
During the preview period you needed to provide the
application/vnd.github.loki-preview+json preview media type in the Accept header to opt-in to the changes. Once the preview period ends, you won't have to specify this custom media type.
There will be two breaking changes when the preview gets removed:
We will be removing this endpoint
PATCH /repos/:owner/:repo/branches/:branch. The breaking change was announced on 06-27-2016.
We will also now be requiring
required-pull-request-reviews when calling the
\protection endpoint. This breaking change was announced on 12-08-2016.
Please update your environments accordingly and if you have any questions, get in touch.
