Zuul is the project gating and automation system that tests and merges changes as well as publishing releases and documentation.
When the cause of a test failure is nondeterministic, developers can request that it be retested by leaving a comment in Gerrit of the form "recheck bug #". This page collects those comments and displays the most commonly seen bugs.
Blueprints targeted for the next release are tracked on this page along with overall progress toward completion.
Important reviews are ranked according to blueprint and bug priority.
During official bug days, this page is updated with real-time stats.
