If you head on over to the official Power BI blog today you’ll see this announcement, and if you’re like me there will be a few things that immediately jump out at you:

1. That’s almost two features per day
2. Dataflows should have a lower-case D
3. Miguel’s profile picture is even older than Matthew’s profile picture

All snark aside^[1], Miguel and the whole dataflows team have been awfully busy, and it’s great to see their work available to Power BI authors. I won’t attempt to repeat what’s in the announcement, but I will highlight the new capabilities that have me most excited:

• Support for data profiling in Power Query Online – we’ve had this in Power BI Desktop for a while, but it’s just as important for dataflows as it is for datasets.
• Better support for files and folders – a lot of the data I play with^[2] these days is in folders full of text files, and Power Query Online hasn’t had the best experience for working with this type of data.
• Better support for query parameters – there are lots of scenarios^[3] where having parameterized queries makes working with dataflows easier, and now Power Query Online makes it easier to work with query parameters.

Do yourself a favor and check out the whole list. Odds are there’s something you’ve been waiting for that will excite you as much as these new capabilities excite me.

And I can’t wait to hear what they are…

^[1] No, I don’t believe that’s possible either, but it is nice to see that you’ve been paying attention.

^[2] Very little of my actual work involves data prep these days, so I need to find data to play with to avoid getting too bored.

^[3] Like this one.
