+Asynchronous HTTP Responses
+===========================
+
+New in GCDWebServer 3.0 is the ability to process HTTP requests aysnchronously i.e. add handlers to the server that generate their ```GCDWebServerResponse``` asynchronously. This is achieved by adding handlers that use a ```GCDWebServerAsyncProcessBlock``` instead of a ```GCDWebServerProcessBlock```. Here's an example:
+
+***Synchronous version***
+```objectivec
+[webServer addDefaultHandlerForMethod:@"GET"
+                         requestClass:[GCDWebServerRequest class]
+                         processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) {
+  
+  GCDWebServerDataResponse* response = [GCDWebServerDataResponse responseWithHTML:@"<html><body><p>Hello World</p></body></html>"];
+  return response;
+  
+}];
+```
+
+***Asynchronous version***
+```objectivec
+[webServer addDefaultHandlerForMethod:@"GET"
+                         requestClass:[GCDWebServerRequest class]
+                    asyncProcessBlock:^(GCDWebServerRequest* request, GCDWebServerCompletionBlock completionBlock) {
+  
+  // Do some async operation like network access or file I/O (simulated here using dispatch_after())
+  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

 Handlers require 2 GCD blocks:
 * The ```GCDWebServerMatchBlock``` is called on every handler added to the ```GCDWebServer``` instance whenever a web request has started (i.e. HTTP headers have been received). It is passed the basic info for the web request (HTTP method, URL, headers...) and must decide if it wants to handle it or not. If yes, it must return a new ```GCDWebServerRequest``` instance (see above) created with this info. Otherwise, it simply returns nil.
-* The ```GCDWebServerProcessBlock``` is called after the web request has been fully received and is passed the ```GCDWebServerRequest``` instance created at the previous step. It must return a ```GCDWebServerResponse``` instance (see above) or nil on error, which will result in a 500 HTTP status code returned to the client. It's however recommended to return an instance of [GCDWebServerErrorResponse](GCDWebServer/Responses/GCDWebServerErrorResponse.h) on error so more useful information can be returned to the client.

 GCDWebServer & Background Mode for iOS Apps
 ===========================================
@@ -220,6 +300,25 @@ Fortunately, GCDWebServer does all of this automatically for you:
 
 HTTP connections are often initiated in batches (or bursts), for instance when loading a web page with multiple resources. This makes it difficult to accurately detect when the *very last* HTTP connection has been closed: it's possible 2 consecutive HTTP connections part of the same batch would be separated by a small delay instead of overlapping. It would be bad for the client if GCDWebServer suspended itself right in between. The ```GCDWebServerOption_ConnectedStateCoalescingInterval``` option solves this problem elegantly by forcing GCDWebServer to wait some extra delay before performing any action after the last HTTP connection has been closed, just in case a new HTTP connection is initiated within this delay.
 
+Debug Builds & Custom Logging
+=============================
+
+When building GCDWebServer in "Debug" mode versus "Release" mode, GCDWebServer logs a lot more information and also performs a number of internal consistency checks. To disable this behavior, make sure to define the preprocessor constant ```NDEBUG``` when compiling GCDWebServer. In Xcode target settings, this can be done by adding ```NDEBUG``` to the build setting ```GCC_PREPROCESSOR_DEFINITIONS``` when building in Release configuration (this is done automatically for you if you use CocoaPods).
+
+It's also possible to replace the logging system used by GCDWebServer by a custom one. Simply define the preprocessor constant ```__GCDWEBSERVER_LOGGING_HEADER__``` to the name of a header file (e.g. "MyLogging.h") that defines these macros:
+
+```
+#define LOG_DEBUG(...)  // Should not do anything if NDEBUG is defined
+#define LOG_VERBOSE(...)
+#define LOG_INFO(...)
+#define LOG_WARNING(...)
+#define LOG_ERROR(...)
+#define LOG_EXCEPTION(__EXCEPTION__)
+
+#define DCHECK(__CONDITION__)  // Should not do anything if NDEBUG is defined or abort if __CONDITION__ is false
+#define DNOT_REACHED()  // Should not do anything if NDEBUG is defined
+```
