The ever-vigilant folks on the internet have spotted that there’s a new M function in the latest versions of Power BI and Excel: Module.Versions. This function, at the time of writing, returns a record with a single field in that contains the version number of the Power Query engine currently in use. So for example if I have a Power Query query in Power BI Desktop that consists of the following code:
Module.Versions()It returns the following:
…where 2.129.181.0 is the version of the Power Query engine in my build of Power BI Desktop.
This function was introduced for people developing Power Query custom connectors who only want to enable certain functionality if the user is running a given version of the Power Query engine or above. I guess if you’re sharing your own M custom functions on the internet then you might want to do the same thing.
