Well the following improvements are listed here ::
http://microtelecom.it/perseus/software.htmlBut yes, I've only had it for about a day now, but really like it, especially the waterfall which has been much improved along with the increased screen size. The one thing I'm having trouble getting used to is the averaging of the spectral screen. Where before I could slow it down to a slow crawl, it now can only be slowed to a fast pace. I hope future updates address this, but it by no means is a show stopper for me.
Keep in mind, I do not and have not used this software to it's limits or tested it from A to Z (I'm more of a casual tuner & listener at best). At this point I haven't even tried recordings and playback yet. Others could probably comment further on this (hopefully).
