There are two buttons available in the Advanced tab of the Options window. These buttons exist to help support the https://dax.guide website.
Typically these buttons would be rarely used and would usually be at the request of one of the DAX Studio development team.
However there is now an extremely wide variety of versions of the tabular engine being used with the following major varieties:
And then there are different service packs and cummulative updates for all of the above plus beta versions and preview releases. So with all this variation it was decided that these buttons should be publically available. So should anyone notice a new function in the code completion that was not listed on dax.guide this gives them an easy way of sending the details of the functions and the engine version to dax.guide.
