It looks like the cadence of updates on new features from the Power BI team is generally this...
* Power BI Desktop changes: early in the month, generally the first week.
* Power BI developer changes: middle of the month.
However we are now at the end of February and it doesn't look like we have had a monthly update yet. Hopefully this means that we are getting a really big update very soon with some significant 'quality of life' improvements to APIs and the like.
