+## Breaking Changes
+
+- **$http:** due to [e1cfb195](https://github.com/angular/angular.js/commit/e1cfb1957feaf89408bccf48fae6f529e57a82fe),
+	   it is now necessary to seperately specify default HTTP headers for PUT, POST and PATCH requests, as these no longer share a single object.
+		 
+	To migrate your code, follow the example below:
+	
+	Before:
+	
+		// Will apply to POST, PUT and PATCH methods
+		$httpProvider.defaults.headers.post = {
+			"X-MY-CSRF-HEADER": "..."
+		};
+
+	After:
+
+		// POST, PUT and PATCH default headers must be specified seperately,
+		// as they do not share data.
+		$httpProvider.defaults.headers.post =
+			$httpProvider.defaults.headers.put =
+			$httpProviders.defaults.headers.patch = {
+				"X-MY-CSRF-HEADER": "..."
+			};
