Apple’s full iOS 7.1 release notes:

Notes and Known Issues

The following issues relate to using iOS SDK 7.1 to develop code.


Bluetooth

Known Issue

32-bit apps running on a 64-bit device cannot attach to BTServer.

CFNetwork

Fixed in iOS 7.1 beta

Previously, if the server-side closed an HTTP request with TCP FIN without sending any bytes of HTTP header or HTTP body, NSURLConnection would synthesize an empty HTTP/1.1 200 OK response. This is now fixed, and the request will result in an error instead of a successful load with a synthesized response.

Notes

A new compatibility behavior has been added to address an issue where some web servers would send the wrong Content-Length value for “Content-Encoding: gzip” content. Previously, NSURLConnection and NSURLSession would send a “network connection was lost” / NSURLErrorNetworkConnectionLost (-1005) error in this situation.
The compatibility behavior applies only if the Content-Length value exactly matches the expanded gzip’d content. It won’t apply for “off by 1” or similar miscounting.

Core Text

Fixed in iOS 7.1 beta

Previously, text drawn with CTFrameDraw did not correctly place lines to account for the paragraphSpacing attribute of NSParagraphStyle. This has been addressed in iOS 7.1 beta.

Crash Logs

Known Issue

Crash logs will not appear in Diagnostics & Usage Data in Settings. The logs will still be available when synced off the device.

GLKit

Fixed in iOS 7.1 beta

If loaded with GLKTextureLoader, pngcrush images that have alpha were not unpremultiplied.

High Precision Timers

Fixed in iOS 7.1 beta

When sleeping or waiting for extremely precise time intervals, timers were delayed by up to 1 millisecond.

iTunes

Known Issue

Loading an iTunes Match library (or your purchased music history) may take much longer than expected, especially on larger libraries. If your library does not sync right away, please wait 30 minutes and try to access it again.

Multipeer Connectivity

Fixed in iOS 7.1 beta

The MCSessioninitWithPeer: method has now been implemented properly.
