Update 2: In iOS 7.1 beta 3, there was an issue with the Shift key on the iOS virtual keyboard. It appears off even when it was turned on and appears on when it was actually turned off. The bug seems to be fixed in the white keyboard at least.

Update 3: Users also notice a slight difference in the slide to unlock animation. It appears to have the highlight covering a wider area as it moves through.

Update 4: The Photo app icon has a small change. However, it is pointed out that the change is not seen on the iPhone 5.

Update 5: Based on the first analyses, Apple has not patched the userland exploits. It still remains to be seen if vulnerabilities in evasi0n7 at the kernel level have already been patched.

Update 6: There was also a minor change with the Phone Dialer. The Add to Contacts below the dialed number has been replaced with a plus (+) button to the left of the dialed number.

Update 7: Users reported there is a little more bounce wile scrolling through the Messages app.

Update 8: The slide to unlock text also gets highlighted when there are new notifications. Users say it looks weird.
