Blocs 3.3 is getting close to release now. Build 6 patches up a few other things, it also adds support for cache busting for page and project attachments (including those added for custom Brics).
Navigation toggle menus are no longer linked. Which means you can have multiple navigations on a single page and they will no longer expand at the same time on mobile when the toggle is hit.
If you still want the linked menu effect just duplicate a navigation Bric. If you want to switch it off on older projects replace the navigation Brics with new ones.
Unless something show stopping turns up over the weekend, Blocs 3.3. will ship early next week.
Anyway have a great weekend folks!
