The latest version is 0.5.2. This corrects a problem with processing Smashwords’ files which include a payment, and handles a minor change that Amazon made to their Kindle sales reports. (It also fixes an error introduced in 0.5.1. That version wasn’t available for more than a few minutes.)
After Worldcon in Reno, and Bubonicon the week after that in Albuquerque, I’ve had enough cons for a while (next up: MileHiCon in Denver at the end of October). I also got some great feedback on what users would like to see in the software. I’ll be introducing some user interface changes to make the easy things (or what should be the easy things) easier. Stay tuned.
