I checked in at Blender Guru and found that most of the info is stuff I already found. There were some things I did not know yet, but nothing that I did not expect. I did see that there are some things that are not in Blender yet which are scheduled for a later build. There are several new features planned for Cycles which will be appearing in 2.65 to 2.67.

It is good to know about Blender Guru, as the schedule can help when deciding when to upgrade to a new build. 

Thanks Hedd.
