+## Changelog
+
+### Version 2.5
+
+- General:
+
+	- [NEW] Unified SDK for accessing HockeyApp on iOS
+
+		- Requires iOS 4.0 or newer
+
+		- Replaces the previous separate SDKs for iOS: HockeyKit and QuincyKit.
+		
+		  The previous SDKs are still available and are still working. But future
+		  HockeyApp features will only be integrated in this new unified SDK.
+
+		- Integration either as framework or Xcode subproject using the sourcecode
+		
+		  Check out [Installation & Setup](Guide-Installation-Setup)
+
+	- [NEW] Cleaned up public interfaces and internal processing all across the SDK
+
+	- [NEW] [AppleDoc](http://gentlebytes.com/appledoc/) based documentation and HowTos
+	
+		This allows the documentation to be generated into HTML or DocSet.
+
+- Crash Reporting:
+
+	- [NEW] Workflow to handle crashes that happen on startup.
+	
+		Check out [How to handle crashes on startup](HowTo-Handle-Crashes-On-Startup) for more details.
+
+	- [NEW] Symbolicate iOS calls async-safe on the device
+
+	- [NEW] Single property/option to deactivate, require user to agree submitting and autosubmit
+		
+		E.g. implement a settings screen with the three options and set
+		`[BITCrashManager crashManagerStatus]` to the desired user value.
+
+	- [UPDATED] Updated [PLCrashReporter](https://code.google.com/p/plcrashreporter/) with updates and bugfixes (source available on [GitHub](https://github.com/bitstadium/PLCrashReporter))
+
+	- [REMOVED] Feedback for Crash Groups Status
+		
+		Please keep using QuincyKit for now if you want this feature. This feature needs to be
+		redesigned on SDK and server side to be more efficient and easier to use.
+
+- Updating:
+
+	- [NEW] Expire beta versions with a given date
+
+	- [REMOVED] Settings screen
+
+		If you want users to be able not to send analytics data, implement the
+		`[BITUpdateManagerDelegate updateManagerShouldSendUsageData:]` delegate and return
+		the value depending on what the user defines in your settings UI.
