Another week, another big update. Grab it from the Source Updates page.
There have been a number of substantial internal changes recently. A lot of this is related to some long-term plans I have around unifying the various device types, removing arbitrary limits, getting rid of hacky old systems, and implementing some core features that have long been requested. I want to extend a special thanks to Zsolt Vasvari who has been doing a lot of the dirty work involved in these changes.
Consider the most recent changes a bit of internal "spring cleaning", and keep an eye out for bugs that might creep in as a result. As you can see from the whatsnew, we are tracking new bugs on the new and improved MAMETesters site, so please make sure you register with the bug database and log anything that seems to be amiss.
