Here's whatsnew per the homepage:
"If one family won't kill him, the other one will!" Know who I'm talking 'bout? ;)
Gottlieb System 1 is (hopefully) bug-free now.
Support for Zaccaria Ski Jump, so all the Zaccaria games are emulated by now.
Full GI support for Who Dunnit and Jack*Bot.
And some long-awaited Gottlieb System 80B / System 3 sound fixes, too.
Anyway, it's all in the whatsnew.txt as usually. Now go grab it!"
