There’s an updated (August 2019) Dynamics 365 Licensing Guide with the changes focusing on two main areas. Firstly, for Forms Pro, there’s clarification on page 26 that Forms Pro survey respondents don’t need to be licensed as long as the survey designer is licensed, and there’s a handy table on page 55 showing the differences between Forms and Forms Pro. Secondly, AI for Sales becomes Sales Insights, and there’s a new Call Intelligence Add-on which adds an additional 1,000 hours of conversation intelligence per month, detailed on page 51.

As usual, you can find this guide here: http://bit.ly/MSLicensingGuides.
