Version 1.1.1

Some tests were failing due to incompatibility issues (firefox and selenium).
I pushed some changes to work around that for now.
These are bundled in this patch release.

Version 1.1.0

Added support for the page visibility api.
If you specify the handle-visibility attribute on the element, the element will check when the page is no longer visible (tab switch or browser minimize) and close the websocket connection.
The connection reopens when the page is visible again.

v1.0.0
