There aren't any changes. The big 3 remain - FreeScan, ProScan and ARC-XT (in no particular order). But like I said in message 5 of this thread, you need to sit down and learn how to work with DMA before you program anything.
My advice is simple - use the links in that message and start reading. Once you have settled on the software and gotten a USB-serial cable working, go to the Virginia forum and ask for a file. Work with 1 or 2 systems at a time - learn how the different kinds of quick keys work. Don't try to do everything at once - it's easy to become overwhelmed with all the different options and things you can do
