One long standing open I haven't addressed has been getting the browser's back button to work. Because page numbers use hashes browser's would ignore a change and not go backwards. I'm please to say that this is no longer the case and moving back (or forward) will function just as you'd expect.
Sticking with the same theme I also made some improvements to how sharing a story on Facebook and Tweeting are handled. Previously if someone mistakenly tapped on the Facebook or Tweet link they would have to load up their accounts to remove the posts, but now all you have to do is press the menu entry a second time (after the check appears) and it will be removed. Google Reader already had this capability. Instapaper does not because their API only supports removal for subscribers.
Aside from those changes there are some more tweaks to how descriptions are displayed and some bug fixes.
