What's new:

=======================================================
Remarks:
1) I have NOT tested this new version. Based on comments during beta-testing, my "gut" is that this may be a rushed (pre-mature) release. Personally, I plan to wait a (good) while... especially for my primary work-horse PC.
2) I only included links for the free version. If you want the paid version, see the top forum link (from which I copied the rest).
