This update fixes a problem in the rank information (the new, lower, requirements weren't being used, and many of the descriptions were munged, and probably had been for some time). That should be fixed now.
A new device was also added: a combination EMF meter and temperature gauge (based on the real-life "MelMeter", including its red LED display), available at some of the higher ranks. This device makes things more convenient since both long-range gauges are bundled into a single device (but you still get credit for both EMF and temperature anomalies separately); and it also reduces the total number of inventory items at higher ranks, making inventory more manageable and opening up another slot.
There should be an additional new device available either later today or tomorrow.
