Released on Friday, November 06, 2015. All issues associated with this milestone can be found using this filter.

Important Upgrade Note for Swift

#3130 fixes a swift interop error that does have a breaking API change if you are using Swift. This was identified after 2.6.2 was released. It changes the method from throws to an error pointer, since that method does return an object and also handles an error pointer, which does not play nicely with the Swift/Objective-C error conversion. See #2810 for additional notes. This affects AFURLRequestionSerializer and AFURLResponseSerializer.

AFHTTPSessionManager now copies its securityPolicy

2.6.0 (08-19-2015)

Released on Wednesday, August 19th, 2015. All issues associated with this milestone can be found using this filter.

Important Upgrade Notes

Please note the following API/project changes have been made:

iOS 6 and OS X 10.8 support has been dropped from the project to facilitate support for watchOS 2. The final release supporting iOS 6 and OS X 10.8 is 2.5.4.
Full Certificate Chain Validation has been removed from AFSecurityPolicy. As discussed in #2744, there was no documented security advantage to pinning against an entire certificate chain. If you were using full certificate chain, please determine and select the most ideal certificate in your chain to pin against.
- Implemented by [Kevin Harwood](https://github.com/Kevin Harwood) in #2856.
The request url will now be returned by the UIImageView category if the image is returned from cache. In previous releases, both the request and the response were nil. Going forward, only the response will be nil.
- Implemented by Chris Gibbs in #2771.
Support for App Extension Targets is now baked in using NS_EXTENSION_UNAVAILABLE_IOS. You no longer need to define AF_APP_EXTENSIONS in order to include code in a extension target.
- Implemented by bnickel in #2737.
This release now supports watchOS 2.0, which relys on target conditionals that are only present in Xcode 7 and iOS 9/watchOS 2.0/OS X 10.10. If you install the library using CocoaPods, AFNetworking will define these target conditionals for on older platforms, allowing your code to compile. If you do not use Cocoapods, you will need to add the following code your to PCH file.

#ifndef TARGET_OS_IOS
  #define TARGET_OS_IOS TARGET_OS_IPHONE
#endif
#ifndef TARGET_OS_WATCH
  #define TARGET_OS_WATCH 0
#endif

This release migrates query parameter serialization to model AlamoFire and adhere to RFC standards. Note that / and ? are no longer encoded by default.
- Implemented by [Kevin Harwood](https://github.com/Kevin Harwood) in #2908.

Note that support for NSURLConnection based API's will be removed in a future update. If you have not already done so, it is recommended that you transition to the NSURLSession APIs in the very near future.
