Has anyone figured out what's changed in these updates? I can't find any documentation on them.

Don't know. There must have also been a Boost 11 update as my installation paths were reset in CCC and I had a new version of it installed into the default location.

Bug fixes maybe?

I've had Dim Pro and Rapture installed for ages and checking the download file version with my installed versions there's an update there too. I done it via the CCC. I'm glad to say that the installer was able to identify my relocated Multisample locations.

Sorry to post that here, it just seems there's a few updates that have caught us off guard and without info.

They did that with the first update.  No published info on what it did.   I clicked on one of the updates (don't remember which one) "for more info" and it just took me to a page on the Cakewalk site advertising products, not to a page with the description of the update.
 
 

Yes, the general theme is that all these updates are great, but we really need more information on what is happening - a change log we can open, a message in CCC, something.

We had an update to those before the new and massive update that was released Friday. Those were updated last week I believe, 

What are "those" John?

Sound Centre and Studio Instruments?

It was more than Sound Center and Studio Instruments.  Mine included a basic Sonar Platinum (Braintree) update, a help file update, Anderton update, Boz Digital Labs, NYC Showroom, Rapture and Dimension Pro.
