To your question about when it will be released - I generally avoid publicly posting a release date, as I then feel I'm under a deadline... and I won't release it until I know it's perfectly stable and ready for heavy use.
In the case of the 8.0, there are some other considerations that may delay a release. I really don't want to put anything out there until I know it's totally stable and ready...
As for the other considerations - I don't like talking about personal stuff on here, but Next Generation Software, Inc. is *me* - completely a one-man operation. And this one man *might* need to have another (minor, hopefully) heart surgery... I had 2 last year, including a pacemaker implant, and there's something wrong with the pacemaker leads now and my new cardiologist is very concerned.
All this and I'm only 41... all caused by a doctor mistake. I can't go into detail because of a pending suit, but let me just say that Indiana is the worst state to have a malpractice case in... the laws protect the doctors, and I'll be in courts for years before I see a dime from any of that...
So anyway, I started 8.0 as a nearly complete rewrite, because after I recovered from the first surgeries I felt fine and thought I was done with hospitals and all that for a while. Internally, VDJ really needed a good rewrite. Mind you, some of my original 1997 code is still perfectly fine, but some of it needed updating pretty badly in order to take advantage of new OS features (touch screens, awesome multimedia/video support, etc).
Plus I've learned quite a lot in the 18 years since I started VDJ - hell, I only had 16 years of programming experience back then! (Yes, I started in 1981 when I was 6 on a Commodore VIC-20)...
So anyway, 8.0's main internals are pretty much overhauled, and it's mostly the cosmetics and finishing touches that need to be completed at this point. At least the 7.x version that's out there is stable for the most part - it just feels outdated (at least to me... lol).
As long as I'm not too drugged up, I should be able to sit up and work while I recover... I can't just sit still and do nothing

But we'll just have to wait and see. If this surgery is as minor as I'm hoping, and recovery is quick, I am still hoping to have it done by the end of the year (so roughly 2 months). I also want to roll out the
www.mydjsongbook.com mobile site offering a ton more features than VDJs built-in app server (like customers' ability to upload selfies, save favorite requests, etc)... big plans, but gotta take care of me first...
