Ok, so if you login to your cloud account, you should now see that there is a new version available, v017. Documentation is now being updated (though 017 is very similar in function to 016 so the changes are minor) for this patch update.
Here are some highlights of the new version (change log will be made available soon)
Supports multiple scenes in blender
Supports blender 2.80 beta - Fixed "grease_pencil" error and numerous other problems
Improved stability - Fixed the "connected:" bug
Now recognises when a render node is using a different version of crowdrender and warns with an exclamation mark next to the render node
Fixed a bug where opening a new file could cause the client to hang, subtly breaking the addon in that the render nodes appeared as though they were connected, but would fail to do anything.
Fixes a bug where the disable render button or tile sizes would not be acted upon, causing nodes that were disabled to render or to use the wrong tile sizes
