+## [1.0.19](https://github.com/ably/ably-js/tree/1.0.19) (2018-11-22)
+
+- Expose rest#setLog method to change log level or handler at runtime
+- Allow jsonp for REST requests even if allowComet is false
+- Expose Rest.Message for node, for consistency with Realtime.Message
+- Add updateOnAttached channel option to force 'update' event even if `resumed` is true
+- Stop a clientId from forcing token auth (https://github.com/ably/ably-js/issues/542)
+- Fix package bloat through mistaken node_modules_node6 includes (due to npm not correctly parsing .gitignore)
+
 ## [1.0.18](https://github.com/ably/ably-js/tree/1.0.18) (2018-09-27)
 
 - Fix bug where connectionSerial was not getting reset after a resume failure (https://github.com/ably/ably-js/pull/540)

 Ably-js has fallback mechanisms in order to be able to support older browsers; specifically it supports comet-based connections for browsers that do not support websockets, and this includes JSONP for browsers that do not support cross-origin XHR. Each of these fallback transport mechanisms is supported and tested on all the browsers we test against, even when those browsers do not themselves require those fallbacks. These mean that the library should be compatible with nearly any browser on most platforms.  Any known browser incompatibilities can be found [here](https://github.com/ably/ably-js/issues?q=is%3Aissue+is%3Aopen+label%3A%22compatibility%22).
