There are a couple of UI changes that I think most people will appreciate. First, the "start/stop recording" button is much bigger, so it's easier to press it with your thumb while you're driving.

And, since I have a couple of CAN devices in my Corvette, so I added support for CAN logging. Currently, only one CAN interface is supported. But, it's cheap:

If you need AFR in your logs, I recommend AEM's X-Series gauges, which support support CAN, so you don't need to wire them into your PCM.
There are also a few new log parameters for the 7603 operating system, but I have to admit that not all of them are reliable.
There are also a couple of tiny improvments to PCM Hammer. The long pause before "Kernel upload 48%" always makes my heart skip a beat, so now it prints "Permission to upload granted" before it start the upload. Also, it logs the VPW messages for OBDX devices.
The next things on my to-do list - which probably won't happen in this order, but which will probably happen:
* a more dashboard-like UI for log parameters, so they'll be easier to read at a distance
* enable/disable log saving via the Air Conditioning switch, or something else that doesn't require reaching for the laptop
* more log parameters for the 7603 operating system
