You need a minimum screen resolution of about 700 pixels width to see our blogs. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Features still in preview as of December 2018

I don't think there's been any movement in the Power BI preview features this month.  Here's what's coming soon:

Preview features

The features waiting in preview.

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

Feature Notes Rating Months
Shape map visual Is this useful map type doomed to spend the rest of eternity in preview? 4 11
M Intellisense Guessing your way round the M language (used to manipulate data loaded into your data model using Query Editor) will become much easier when this is introduced. 8 4
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 11
Get data from PDF files Impressively, you'll be able to load data into a model from tables in a PDF file. 7 4
Enable column profiling Query Editor will assess the quality of data when you import a column and list possible errors. 8 3
Dates as a hierarchy When you create a date hierarchy, this will appear in the field well. 2 11
Python support The ability to specify a Python program which outputs data as a data source. 3 5
Incremental Refresh Policies For Power BI Premium only, to begin with, you'll be able to update only data which has changed. 7 8
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 4
Enable fuzzy merge You'll be able to control how similar items have to be to be considered the same when merging data. 6 3
Modelling view A whole new way of looking at relationships, which will also give you the ability to apply changes to multiple fields/tables at the same time. 9 2
New filter experience A new customisable and easy-to-use filter pane, with filters that you can lock and hide. 9 2
Q&A Live Connect This will allow you to ask questions against live connections to databases. 2 1


  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.
