Articulate 360 is a great resource for help

Articulate 360 has an interactive blog on each new release that will take you to their updates.

Alternatively, if you select, "See Release Notes" it will take you to the specific updates for each tool of Articulate 360.

I also found the articulate community called e-learning heroes, helpful to find immediate answers or solutions to your questions. The community is very responsive and helpful, even an Articulate customer service support team will respond with suggestions.
