 - We have replaced the previous monitoring API with a brand new REST API that will offer us the required flexibility to expose additional information in the future. You can take a look at the available endpoints and the associated responses in this [wiki article](https://github.com/xatkit-bot-platform/xatkit-releases/wiki/REST-API). Note that this API is far from perfect, and we already have a couple of opened issues to improve it (see [here](https://github.com/xatkit-bot-platform/xatkit-runtime/issues/258) and [here](https://github.com/xatkit-bot-platform/xatkit-runtime/issues/257)).
 - `RuntimeActions` creating a dedicated `XatkitSession` (e.g. messaging actions getting a session based on the targeted channel) now update the execution rule's session to reflect the session shift. This allows, in the context of an event reaction bot, to set session variables in reaction to an *event*  that will be merged in the session corresponding to the messaging action triggered within the rule.
 - `AdminHttpHandler` now uses a list of test client names to simulate multi-client bots using the web-based component. The name is printed in the rendered HTML page, and used to initialize the *xatkit-react* client.
+- Support for bots hosted on `https` domains. The Xatkit configuration can now contain a `xatkit.server.ssl.keystore` property specifying the location of the keystore to use to sign http responses. Additional properties specifying keystore password are also required, check [Xatkit configuration options](https://github.com/xatkit-bot-platform/xatkit-releases/wiki/Xatkit-Options) for more information.
