Quote - Among other things, they fixed some aspects of symmetry in rigging, which makes it a pretty mandatory update for me.

Weren't those already fixed with SR2 ?

When running the SR2.1 installer, it says that it's going to update Poser to 8.0.2.10911 (at least for Windows).
The following window containing the detailed information about the update shows the text from the SR2 ReadMe.
I didn't go thru with the installation, so I don't know, if there is a "final" ReadMe for this update saved to the Poser 8 directory.

 

Yesterday's the past, tomorrow's the future, but today is a gift. That's why it's called the present.
