We just pushed up Acorn 3.5 for our direct customers. The big focus for the release was bug fixes, but we managed to slip in some new features as well. A new non-contiguous option for the magic wand tool, File ▸ Layer Export, new layer blend modes (Divide, Lighter Color, Darker Color, Hard Mix, and Subtract ), and a new filter for making fancy sunbursts.
There were a handful of changes, as well as new APIs for scripters. Visit the release notes for the full details.
