All issues associated with this milestone can be found using this [filter](https://github.com/AFNetworking/AFNetworking/issues?q=milestone%3A2.6.2+is%3Aclosed). ### Important Upgrade Note for Swift * [#3130](https://github.com/AFNetworking/AFNetworking/pull/3130) fixes a swift interop error that does have a breaking API change if you are using Swift. This was [identified](https://github.com/AFNetworking/AFNetworking/issues/3137) 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](https://github.com/AFNetworking/AFNetworking/issues/2810) for additional notes. This affects `AFURLRequestionSerializer` and `AFURLResponseSerializer`. #### Added * `AFHTTPSessionManager` now copies its `securityPolicy` * Fixed by [mohamede1945](https://github.com/mohamede1945) in [#2887](https://github.com/AFNetworking/AFNetworking/pull/2887). #### Updated * Updated travis to run on 7.1 * Fixed by [kcharwood](https://github.com/kcharwood) in [#3132](https://github.com/AFNetworking/AFNetworking/pull/3132). * Simplifications of if and return statements in `AFSecurityPolicy` * Fixed by [TorreyBetts](https://github.com/TorreyBetts) in [#3063](https://github.com/AFNetworking/AFNetworking/pull/3063). #### Fixed * Fixed swift interop issue that prevented returning a nil NSURL for a download task * Fixed by [kcharwood](https://github.com/kcharwood) in [#3133](https://github.com/AFNetworking/AFNetworking/pull/3133). * Suppressed false positive memory leak warning in Reachability Manager * Fixed by [kcharwood](https://github.com/kcharwood) in [#3131](https://github.com/AFNetworking/AFNetworking/pull/3131). * Fixed swift interop issue with throws and Request/Response serialization * Fixed by [kcharwood](https://github.com/kcharwood) in [#3130](https://github.com/AFNetworking/AFNetworking/pull/3130). * Fixed race condition in reachability callback delivery * Fixed by [MichaelHackett](https://github.com/MichaelHackett) in [#3117](https://github.com/AFNetworking/AFNetworking/pull/3117). * Fixed URLs that were redirecting in the README * Fixed by [frankenbot](https://github.com/frankenbot) in [#3109](https://github.com/AFNetworking/AFNetworking/pull/3109). * Fixed Project Warnings * Fixed by [kcharwood](https://github.com/kcharwood) in [#3102](https://github.com/AFNetworking/AFNetworking/pull/3102). * Fixed README link to WWDC session * Fixed by [wrtsprt](https://github.com/wrtsprt) in [#3099](https://github.com/AFNetworking/AFNetworking/pull/3099). * Switched from `OS_OBJECT_HAVE_OBJC_SUPPORT` to `OS_OBJECT_USE_OBJC` for watchOS 2 support. * Fixed by [kylef](https://github.com/kylef) in [#3065](https://github.com/AFNetworking/AFNetworking/pull/3065). * Added missing __nullable attributes to failure blocks in `AFHTTPRequestOperationManager` and `AFHTTPSessionManager` * Fixed by [hoppenichu](https://github.com/hoppenichu) in [#3057](https://github.com/AFNetworking/AFNetworking/pull/3057). * Fixed memory leak in NSURLSession handling * Fixed by [olegnaumenko](https://github.com/olegnaumenko) in [#2794](https://github.com/AFNetworking/AFNetworking/pull/2794).

[](https://travis-ci.org/AFNetworking/AFNetworking) For detailed information about migrating to AFNetworking 3.0.0, please reference the [migration guide](https://github.com/AFNetworking/AFNetworking/wiki/AFNetworking-3.0-Migration-Guide). All future 3.0.0 beta changes will be tracked with this [filter](https://github.com/AFNetworking/AFNetworking/issues?q=milestone%3A3.0.0+is%3Aclosed). ### New * AFNetworking relies exclusively on `NSURLSession`. All `NSURLConnection` support has been removed from AFNetworking. * AFNetworking now supports installation through [Carthage](https://github.com/carthage/carthage). * All UIKit categories are now build on `NSURLSession`. * Image downloading has been rebuilt using the image downloading architecture from [AlamofireImage](https://github.com/Alamofire/AlamofireImage). * AFNetworking now supports tvOS and Xcode 7.1 * Example project has been refactored to include support for all supported platforms. * Test targets have been completely refactored * Many other minor improvements. The full changelog will be available for the final 3.0.0 release.

**Future Compatibility Note** Note that AFNetworking 3.0 will soon be released, and will drop support for all `NSURLConnection` based API's (`AFHTTPRequestOperationManager`, `AFHTTPRequestOperation`, and `AFURLConnectionOperation`. If you have not already migrated to `NSURLSession` based API's, please do so soon. For more information, please see the [3.0 migration guide](https://github.com/AFNetworking/AFNetworking/wiki/AFNetworking-3.0-Migration-Guide). **Fixed** * Fixed a bug that prevented empty x-www-form-urlencoded bodies. * Fixed by [Julien Cayzac](https://github.com/jcayzac) in [#2868](https://github.com/AFNetworking/AFNetworking/pull/2868). * Fixed bug that prevented AFNetworking from being installed for watchOS via CocoaPods. * Fixed by [Kevin Harwood](https://github.com/kcharwood) in [#2909](https://github.com/AFNetworking/AFNetworking/issues/2909). * Added missing nullable attributes to `AFURLRequestSerialization` and `AFURLSessionManager`. * Fixed by [andrewtoth](https://github.com/andrewtoth) in [#2911](https://github.com/AFNetworking/AFNetworking/pull/2911). * Migrated to `OS_OBJECT_USE_OBJC`. * Fixed by [canius](https://github.com/canius) in [#2930](https://github.com/AFNetworking/AFNetworking/pull/2930). * Added missing nullable tags to UIKit extensions. * Fixed by [Kevin Harwood](https://github.com/kcharwood) in [#3000](https://github.com/AFNetworking/AFNetworking/pull/3000). * Fixed potential infinite recursion loop if multiple versions of AFNetworking are loaded in a target. * Fixed by [Kevin Harwood](https://github.com/kcharwood) in [#2743](https://github.com/AFNetworking/AFNetworking/issues/2743). * Updated Travis CI test script * Fixed by [Kevin Harwood](https://github.com/kcharwood) in [#3032](https://github.com/AFNetworking/AFNetworking/issues/3032). * Migrated to `FOUNDATION_EXPORT` from `extern`. * Fixed by [Andrey Mikhaylov](https://github.com/pronebird) in [#3041](https://github.com/AFNetworking/AFNetworking/pull/3041). * Fixed issue where `AFURLConnectionOperation` could get stuck in an infinite loop. * Fixed by [Mattt Thompson](https://github.com/mattt) in [#2496](https://github.com/AFNetworking/AFNetworking/pull/2496). * Fixed regression where URL request serialization would crash on iOS 8 for long URLs. * Fixed by [softenhard](https://github.com/softenhard) in [#3028](https://github.com/AFNetworking/AFNetworking/pull/3028).

[2.6.0](https://github.com/AFNetworking/AFNetworking/releases/tag/2.6.0) (08-18-2015) Released on Tuesday, August 18th, 2015. All issues associated with this milestone can be found using this [filter](https://github.com/AFNetworking/AFNetworking/issues?q=milestone%3A2.6.0+is%3Aclosed). **Important Upgrade Notes** Please note the following API/project changes have been made: * iOS 6 support has now been removed from the podspec. Note that iOS 6 support has not been removed explicitly from the project, but it will be removed in a future update. * **Full Certificate Chain Validation has been removed** from `AFSecurityPolicy`. As discussed in [#2744](https://github.com/AFNetworking/AFNetworking/issues/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/kcharwood) in [#2856](https://github.com/AFNetworking/AFNetworking/pull/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](https://github.com/chrisgibbs) in [#2771](https://github.com/AFNetworking/AFNetworking/pull/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](https://github.com/bnickel) in [#2737](https://github.com/AFNetworking/AFNetworking/pull/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 complile.

- Fix behavior of SSL pinning. In case of `validatesDomainName == YES`, it now explicitly uses `SecPolicyCreateSSL`, which also validates the domain name. Otherwise, `SecPolicyCreateBasicX509` is used. `AFSSLPinningModeCertificate` now uses `SecTrustSetAnchorCertificates`, which allows explicit specification of all trusted certificates. For `AFSSLPinningModePublicKey`, the number of trusted public keys determines if the server should be trusted.
