By earlier versions read the current latest - there is one known bug, and a couple of things I could have done differently to make broken clients behave better. The bug lets ppl see stuff they shouldn't, but doesn't allow anything more than that.
As other ppl have also said, it's still shareware, but ppl can use the current version fully for free - but future versions will be more expensive (free upgrades for registered ppl). As Ryu also said, I lost the source from versions 2.64 onwards - that was a *lot* of coding, and will teach me not to buy cheap cdr's any more . :-(
