Apple releases iOS 7.1 beta

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

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

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.

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.

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

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

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

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.

The MCSessioninitWithPeer: method has now been implemented properly.
