Me too Jonesey, but there's more yellow lights than documented updates so I'm not sure what I want to download. Can't wait for improvements to the CCC.
You can just do the documented updates for now...
SONAR Core
Platinum Instrument Collection
Anderton Collection
Drum Replacer (which is not mentioned in the eZine, sorry)
...and download the other ones when the new CCC appears. Or you can download them over time, like when you take a break or whatever. Probably makes sense to do that before the new CCC appears so they're compatible with it out of the chute.
Definitely makes more sense to do the updates prior to the Cakewalk Command Center update for compatibility purposes. If you don't, nothing will break, but if you want an accurate reflection of "what is installed" this is the best thing to do. Ultimately one of or goals with updating all of the content with this release was in preparation for some Command Center updates. Essentially the coming update is much smarter about handling what is installed, what isn't installed, and what is or isn't up to date. This required installer changes as well though, hence all of the yellow lights everyone is seeing today.
As Craig mentioned though, the core functionality changes are outlined by the eZine. If a yellow light on "D-Pro" doesn't bother you then you can easily ignore it.
Edit for clarification
