According to Amazon, the improvements include the usual miscellaneous bug fixes and performance improvements as well as new support for the free trial period for textbooks, and support for "Japan marketplace" (huhwhat?)
Not having a Mac myself, I can't offer a first-hand report on how well the app performs after the update. But I did notice that the update is getting negative reviews on Twitter:
Why do I get my hopes up with every Kindle for Mac update, Amazon? Why do you dash them?

Well, the Kindle app for the Mac got an update today. At least it doesn’t make VoiceOver crash anymore, but it’s still 100% inaccessible.
