In case you missed it, Microsoft has published the “2020 release wave 1” release plan for the Power Platform, including Power BI.
You can find the goodness here: Power Platform: 2020 release wave 1 plan.
Even though you won’t see the term “roadmap” anywhere in the release plan docs, this is how I think of them – because they’re the best, most current, and most complete public view of what Microsoft is planning for Power BI and the rest of the Power Platform.
Check it out today, and also check back in as the release plan is updated periodically as the teams have more clarity and detail to share.
 Yes, these were called “release notes” not too long ago. No, I don’t know why picking a name and sticking with it is so hard. Yes, I will do my best to call these “roadmap” even though this isn’t their official name. Hashtag power rebel.
 I think the docs team publishes updates every week, but not every article gets modified in each update. I’m also not 100% sure about the weekly publishing schedule, which is why I buried this in a footnote that no one will actually read.
