I've recently updated the gateway to 8.1.42 to get access to the new Micrologix 800 driver but it is missing from the device driver list.

Is this driver available to download anywhere? Was it removed since it was released 2 versions ago?

One other thing to note is when upgrading your gateway, by default I believe it only selects the drivers you previously installed, so during the update, you could have selected the new driver to be installed then also without manually having to download it.
