Here's the change log:
QuoteBuild 4.7.08 (Frontier Build)
Radiance HDR: Images can be saved in the Radiance HDR (.hdr) format in the Professional Edition and Creative Edition.
EXR in Creative: Images and heightfields can be saved to EXR files in the Creative Edition as well as the Professional Edition.
Multi-channel EXR: You can choose to embed extra output images into the main output as a multi-channel EXR. This includes the full set of Render Elements in the Professional Edition and the tgAlpha element in the Creative Edition. Options include regular Multi-Layer EXR and Multi-Part EXR.
Added "Set all objects to hidden" to the action menu of the Objects Node List.
I'm very excited about the new multi-channel EXR capabilities. But how do I get it to work, and what are the limitations? Like, I have a scene with several types of foliage: trees, bushes, grass, etc., and I need to create an alpha for each. The method I've been using is to render out a separate pass for each of the elements. Can all these passes be embedded now? I've tried a simple test with a render layer node assigned (visible foliage, holdout for the rest). But it didn't seem to work. Also, I didn't see any documentation on this new function.

Terragen's multi-layer and multi-part EXRs can be used to store Render Elements in one file instead of many. But it only applies to Render Elements, i.e. anything that can be output from a single render:

Anything that requires a separate Render Layer (eg. to show or hide different objects) still requires each layer to be rendered separately.
