Infuse 6 includes quite a few new major additions and improvements, and depending on how you use Infuse these may or may not make a big impact for you.
Development isn’t stopping with 6.0 and we’re continuing to work on great new features and additions (like we did with Infuse 5 Infuse Release Notes | Firecore) for 6.1, 6.2, etc… These are generally made available when they are ready, and not held back for a major release. For example, we introduced a full iOS redesign in Infuse 5.6 (Infuse 5.6 - A Fresh New Look + HDR | Firecore), whereas a more traditional approach would be to release an update like this as 6.0.
This thread has a look at some of the things we’re working to add for upcoming versions, and is updated regularly.
Hope this helps!
