Just a quick note about the updates we have pushed live today.
Being notified about a major bug in Luxrender 1.2, which will cause version 1.2.1 to be released soon, we have updated our build to incorporate the fix for this bug.
Also, since Blender 2.66a is going to be released tomorrow, we went ahead and pushed it live on our farm today. This includes a number of fixes and makes the 2.66 version even more stable.
