+### 1.13.0 (2015-03-05)
+
+  * Added Registry::hasLogger to check for the presence of a logger instance
+  * Added context.user support to RavenHandler
+  * Added HipChat API v2 support in the HipChatHandler
+  * Added NativeMailerHandler::addParameter to pass params to the mail() process
+  * Added context data to SlackHandler when $includeContextAndExtra is true
+  * Added ability to customize the Swift_Message per-email in SwiftMailerHandler
+  * Fixed SwiftMailerHandler to lazily create message instances if a callback is provided
+  * Fixed serialization of INF and NaN values in Normalizer and LineFormatter
+
 ### 1.12.0 (2014-12-29)
 
   * Break: HandlerInterface::isHandling now receives a partial record containing only a level key. This was always the intent and does not break any Monolog handler but is strictly speaking a BC break and you should check if you relied on any other field in your own handlers.
