Welcome Rick,
Blocs is very actively being developed, the road map for version 3 is currently not public to help us keep a few surprises for our users and competitors 
But I have shared snippets here and there so here’s a few.
- New bric bar / library UX
- New scroll animation effects
- Bootstrap 4 support
- Ability to add custom data attributes
- Refreshed UI
This is by no means a complete list. Release date for Blocs 3 is not confirmed but we hope to ship it before the end of 2018.
