We've just pushed out Acorn 4.5.4 for direct customers (ie, customers who purchased Acorn from our online store). We submitted Acorn 4.5.4 to the App Store yesterday, but because of the usual delays at Apple, it'll probably take a week or more for it to show up there.
So hang tight, it's coming.
This release includes a handful of bug fixes, so make sure to update when you get a chance.
The release notes are available as always.
