After sideloading the release, I checked out my pet bugs.
The annotation selection bug is still happening. This is where moving the right cursor causes the left cursor to move sometimes. And vice versa.
The Show Bookmark on Page bug is still happening. This is where you bookmark a page (upper-right corner). Then use the bookmark (through the Annotations menu, selecting the menu for the bookmark, then selecting Show on Page). At this point, the bookmarked page is shown, but the upper menu bar is displayed, and won't go away until you open up the lower menu bar, then do the normal tap on screen to make both menu bars disappear. During the time that the upper menu bar is erronously displayed, the page turns function normally, except that the upper menu bar hides the top line of text.
