From Jesse’s post on the list..

In a meeting today between Release Engineering, QA, and various team leads, we decided to enact a 7 day slip of the Fedora 11 release date. The primary reason behind this slip is the state of our blocker bug: We cannot begin Release Candidate phase until the blocker bugs re closed or at least in MODIFIED state. We are not there today, which would be our last day to enter RC phase and still have enough time to release on the 26th. We hope to enter RC phase in the next couple days, and hit our new target, June 2nd.

Freeze breaks for critical bugs will still be accepted, however trivial
bug fixes should be pushed as updates via bodhi. Thanks!
