Release is live. Unfortunately, we have had some issues this morning to answer some of the comments below.


 * The "source" and "visual" buttons have gone missing for a number of users from the editor. This appears to be due to some caching on a per-wiki basis. We are working on fixing it ASAP.
 * Message Wall has disappeared from Wiki Labs, we are putting it back ASAP.
 * The H2 tweaks detailed above had a configuration error when committing the code, so at this time, those changes have not been applied. I am not sure when they will be released.
