March 2019 preview

The features in preview as of March 2019.

Here's my take on what to expect from each feature:

Feature Notes Rating Months
Shape map visual Fourteen months and counting ... 4 14
M Intellisense Autocompletion for the M Query Editor formula language. 8 7
Spanish language support for Q&A Will Power BI show better answers when you put your question in Spanish?  Time will tell - hasta luego. 2 14
Get data from PDF files Impressively, you'll be able to load data into a model from tables in a PDF file. 7 7
Enable column profiling Query Editor will assess the quality of data when you import a column and list possible errors. 8 6
Python support The ability to specify a Python program which outputs data as a data source. 3 8
Incremental Refresh Policies For Power BI Premium only, to begin with, you'll be able to update only data which has changed. 7 11
Manage aggregations You will be able to load data at a summarised level into a data model (thus taking up far less space), while still allowing users to drill down to a lower level. 6 7
Enable fuzzy merge You'll be able to control how similar items have to be to be considered the same when merging data. 6 6
New filter experience A new customisable and easy-to-use filter pane, with filters that you can lock and hide (Microsoft keep announcing updates to this, but it remains in preview for now). 9 5
Q&A Live Connect This will allow you to ask questions against live connections to databases. 2 4
Key influencers visual A new visual showing the main factors influencing changes in a key metric (such as sales). 7 2


  1. The subjective Wise Owl rating goes from 1 (of little importance for most Power BI Desktop users) up to 10 (will have a huge impact on your everyday report designs).
  2. The final column shows the number of months that each feature has spent in preview since I started tracking it.
