The long answer is: The last "real" update that PMI has made to the PMI-ACP Exam was in 2016. In that year the PMI-ACP Examination Content Outline was updated and additional domains were added. Back then we compared The Agile PrepCast to the new requirements, determined any missing parts, and then developed and recorded a number of new lessons and interviews in order to cover the new requirements.
Since then, there have been no changes to the examination content outline, which means that the course is still up to date.
Last year, PMI published The Agile Practice Guide. Since then PMI has made MINOR adjustments to the exam. They called it a "lexicon update". For example, they now use the word "iteration" instead of "sprint". But no major changes were made that would require us to update the PrepCast.
We have, however, gone through many of the questions in The PMI-ACP Simulator and made a number of updates. We have included The Agile Practice Guide as a reference (where it made sense) and we have adjusted the style and phrasing of the questions in the simulator to what students tell us that they are seeing on the exam.
So... back to the short answer: Yes. Both are updated.
I'm interested by buying "Agile PrepCast Elite" to prepare PMI-ACP certification but I can't see any information regarding wether the courses and exam simulation have been updated to take into account the last updates of PMI exam on 2018.
