Fix associated object bug in UIKit extensions (#3872 )

Search for default pinned certificates in the main bundle (#3752 )
Using `[NSBundle bundleForClass:[self class]]` is dangerous because the code will behave differently depending on how AFNetworking is integrated. * If it is integrated as a static library (for example using CocoaPods), certificates will be searched in the main bundle. * If it is integrated as a framework (for example using Carthage), certificates will be searched in the AFNetworking framework. Even though this behavior is documented, this is dangerous. Using the main bundle makes the behavior deterministic. Fixes #3575

 Reachability can be used to determine background information about why a network operation failed, or to trigger a network operation retrying when a connection is established. It should not be used to prevent a user from initiating a network request, as it's possible that an initial request may be required to establish reachability.

+
+### 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`

 ## [2.6.0](https://github.com/AFNetworking/AFNetworking/releases/tag/2.6.0) (08-19-2015)

-###Important Upgrade Notes
+### 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.
+* 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](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/Kevin Harwood) 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. If you do not use Cocoapods, you will need to add the following code your to PCH file.

 **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.

-AFNetworking is a delightful networking library for iOS and Mac OS X. It's built on top of the [Foundation URL Loading System](http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/URLLoadingSystem/URLLoadingSystem.html), extending the powerful high-level networking abstractions built into Cocoa. It has a modular architecture with well-designed, feature-rich APIs that are a joy to use.

It has a modular architecture with well-designed, feature-rich APIs that are a joy to use.

 Perhaps the most important feature of all, however, is the amazing community of developers who use and contribute to AFNetworking every day. AFNetworking powers some of the most popular and critically-acclaimed apps on the iPhone, iPad, and Mac.

-### Installation with CocoaPods
+## Installation
+AFNetworking supports multiple methods for installing the library in a project.

-[CocoaPods](http://cocoapods.org) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like AFNetworking in your projects. See the ["Getting Started" guide for more information](https://github.com/AFNetworking/AFNetworking/wiki/Getting-Started-with-AFNetworking).
+## Installation with CocoaPods
+
+[CocoaPods](http://cocoapods.org) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like AFNetworking in your projects. See the ["Getting Started" guide for more information](https://github.com/AFNetworking/AFNetworking/wiki/Getting-Started-with-AFNetworking). You can install it with the following command:
+
+```bash
+$ gem install cocoapods
+```
+
+> CocoaPods 0.39.0+ is required to build AFNetworking 3.0.0+.

 #### Podfile

+To integrate AFNetworking into your Xcode project using CocoaPods, specify it in your `Podfile`:
+
 ```ruby
-platform :ios, '7.0'
-pod "AFNetworking", "~> 3.0"
+source 'https://github.com/CocoaPods/Specs.git'
+platform :ios, '8.0'
+
+target 'TargetName' do
+pod 'AFNetworking', '~> 3.0'
+end
 ```

+Then, run the following command:
+
+```bash
+$ pod install
+```
+
+### Installation with Carthage
+
+[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
+
+You can install Carthage with [Homebrew](http://brew.sh/) using the following command:
+
+```bash
+$ brew update
+$ brew install carthage
+```
+
+To integrate AFNetworking into your Xcode project using Carthage, specify it in your `Cartfile`:
+
+```ogdl
+github "AFNetworking/AFNetworking" ~> 3.0
+```
+
+Run `carthage` to build the framework and drag the built `AFNetworking.framework` into your Xcode project.

 ## Unit Tests

-AFNetworking includes a suite of unit tests within the Tests subdirectory. In order to run the unit tests, you must install the testing dependencies via [CocoaPods](http://cocoapods.org/):
-
-    $ cd Tests
-    $ pod install
-
-Once testing dependencies are installed, you can execute the test suite via the 'iOS Tests' and 'OS X Tests' schemes within Xcode.
-
-### Running Tests from the Command Line
-
-Tests can also be run from the command line or within a continuous integration environment. The [`xcpretty`](https://github.com/mneorr/xcpretty) utility needs to be installed before running the tests from the command line:
-
-    $ gem install xcpretty
-
-Once `xcpretty` is installed, you can execute the suite via `rake test`.
+AFNetworking includes a suite of unit tests within the Tests subdirectory. These tests can be run simply be executed the test action on the platform framework you would like to test.
