Bug Fixes
The root disk utilization graph in the Management Console was missing on AWS Nitro instance types.
The Alambic storage service could hit a file descriptor limit that could cause the kernel to hang and other services to log errors.

When a repository is locked users could still directly visit pull request URLs and modify the reviewers.
A team created via the API V3 would not automatically add its creator as a maintainer, which caused it to be inaccessible to that person.

The DNS resolution for GitHub Connect could timeout.
