iOS 9b5 notes

Still a little bit buggy, but getting there.  Some apps that crashed at startup now work for me (in fact, I now have no apps that crash at startup).  Status bar now reappeared in Reeder.

Problems:

• still a bit laggy.  This is most noticeable when the device thinks I picked it up in landscape and takes its time rotating, in multiple steps, to portrait. Seemingly every time I pick up the phone.
• Mail is flaky, particularly on my iPad Air 2.  Stray attachment icons floating around the message view, even in messages without attachments (killing mail and restarting solves).
• Battery usage is a bit high still. Burning about an extra 10-20% of battery in a day, at least on my iPhone 6+.
• News app still a little slow to show me new materials. Sometimes you have to tap between tabs to get it to load new material.
