Apple seeds iOS 8 beta 2 build 12A4297e to developers on Tuesday, June 17, 2014.
This build seems to be a lot more stable than the first iOS 8 beta which crashed at least three times within the first hour. iOS 8 beta 2 seems to be stable enough that I told my colleagues they could install it if they would.
I installed iOS 8 beta on an iPhone 5s and iPad Air instead of on older devices; they are the only 64-bit iPhone and iPad I have. Apple is going full on 64-bit with the upcoming iOS devices.
I noticed that my iPad Air rings whenever my iPhone 5s rings. It seems that phone call handoff is working between the two devices. Overall, I’m really excited with iOS 8.

Apple seeds OS X Yosemite Developer Preview 2 build 14A261i on Tuesday, June 17, 2014.
The first OS X Yosemite Developer Preview was too buggy for my 2010 MacBook Pro. The font doesn’t look right and I suspected that it was designed to look best on Retina Display. The support for NVIDIA GeForce GT 330M was pretty abysmal.
I have not had enough time using OS X Yosemite Developer Preview 2 to find out if it’s going to run well on older Macs. Time will tell.
