Due to the intricacies of the Apple App Store, we have a few different versions available:

• CF iViewer is a legacy product, only used for old installations.
• iViewer4 is the latest stable version.
• iViewer Next is the latest public beta version.

We also have a private beta version for testing before releasing iViewer Next to the public.

So the release order goes:

1. Internal Testing
2. Private Beta Testing (iViewer TF)
3. Public Beta Testing (iViewer Next)
4. Public Stable Release (iViewer4)

As we progress, each major version will remain on the app store as it's own app.
So once we hit iViewer5, it will become the public stable release, whilst iViewer4 will join CF iViewer as a legacy product.
