Apple has just seeded iOS 6.1 beta 2 to developers for download and testing, though it’s not yet clear what changes the new update holds. The first version of iOS 6.1, which BGR reported would be released about the holiday timeframe, only included minimal changes on the surface layer. We’ll report back on anything we can find, though. In the meantime here’s the official change log:

Notes and Known Issues

The following issues relate to using iOS SDK 6.1 beta 2 to develop code.

Apple TV

Notes

None.

Known Issues

When browsing the iTunes Store, TV Shows is missing Networks, Genres, and Genius from the top menu.

The Top Movies and Top TV Shows grids are missing the featured carousels, as well as several featured shelves.

Podcasts is missing the Providers item from the top menu.

Core Image

Notes

None.

Known Issues

In iOS 6.0 and later, Core Image introduced new filters to the set provided in iOS 5. The complete set of filters can be found in Core Image Filter Reference.

Also in iOS 6.0 and later, Core Image allows for the creation of CIImage objects that reference OpenGL texture objects via the imageWithTexture:size:flipped:colorSpace: method.

iCloud

Notes

None.

Known Issues

In iOS 6.1 beta 1, you will not be able to upgrade or downgrade your iCloud storage (5 GB is free). As a workaround, please use either the latest OS X or a device running iOS 6.0.

Maps

Notes

In iOS 6.1, the Map Kit framework introduces the MKLocalSearch, MKLocalSearchRequest, and MKLocalSearchResponse classes. Apps can use these classes to perform map-based searches for addresses and points of interest. The results are then delivered to the app as an array of map item objects. For information about these new classes, see Map Kit Framework Reference.

Known Issues

None.

Passbook

Notes

As of iOS 6.1, the relevance behavior has changed for boarding passes that include both a relevant date and a relevant location. The date must match for these passes to be relevant. If both the date and location match, they are relevant for a longer window of time. You are encouraged to provide both pieces of information when they make sense for your passes.

Known Issues

None.

Settings

Notes

In iOS 6.1, a new Reset Advertising Identifier button has been added to Advertising Settings. This button resets the Advertising Identifier so that future requests will return a different value.

Known Issues

None.

Simulator

Notes

This release does not support testing In-App Purchase in iOS Simulator. For apps that use this feature, please test on a device.

Known Issues

None.

Social

Notes

Weibo shows up in the Settings app only if a Chinese keyboard is enabled.

When using the iOS 6.1 SDK on OS X v10.8 (Mountain Lion), if you use the iOS 5.0 or iOS 5.1 “Legacy SDK” in iOS Simulator, you will not be able to sign in to Twitter via the Settings pane and Twitter.framework will not work correctly. If you need to test Twitter features, you will need to choose either the iOS 6.1 or iOS 6.0 Simulator run destination or test with iOS 5.x on a device. These problems do not occur when running Simulator on OS X v10.7 (Lion).
