We posted the patch notes last week when Zarhym released them, and they're after the break so you can become reacquainted with the small changes that'll be happening. If there are suddenly new notes tomorrow we'll let you know.
When a mirror is available for download we'll get a post up; probably sometime early tomorrow afternoon. This patch is also likely a harbinger of maintenance tomorrow, however there has been no official announcement yet.
The patch notes after the break.
