Apple Releases iOS 7.1 Beta to Developers [Changelog]

Apple has released the first iOS 7.1 beta to developers one week after the company rolled out iOS 7.0.4 to fix a FaceTime bug. The update can now be downloaded from Apple's developer center. You can read the complete release notes below.

iOS 7.1 Beta

Last week iOS 7.0.4 was deemed jailbreak safe by the jailbreaking community. However, evad3rs team member MuscleNerd advised users with jailbroken devices to avoid it because there is no going back once you upgrade. The iOS 7.0.4 update brought a few bug fixes and minor improvements.

iOS 7.1 beta 1 also includes a few bug fixes and needed performance tweaks. Other notable changes include a new Yahoo logo in the Notification Center, a new "Use Dark Keyboard" option and a new "Upload Burst Photos" option.

iOS 7.1 Changelog via BGR:

Notes and Known Issues
The following issues relate to using iOS SDK 7.1 to develop code.

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

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.

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.

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.

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.
