Power BI Desktop November 2018 version - Backward compatibility
Memorable MemberI have also found this.
Not great as I use the PowerBI Report Server, which is still in line with August Release.
Fortunately for me I found it before I broke any important docs (though most are in source control).
I'm going to have to downgrade to October. I could use this version, but still save in the August RS version before uploading as long as I didn't use any new features.
About a year ago versions were incompatible, but recently they have been less fussy and I'd got used to this. Most of my users are on older versions and they have to update using SSCM to delivery. I hope this is a one off issue.
I suspect it may be related to composite models being generally available.
Community ChampionI always found this to be standard behavior. I have a particular report that has a bug using the Oct 2018 version, so I have to downgrade (uninstall Oct, install Aug) to Aug 2018 version to update that report, then upgrade again to Oct 2018 to edit/use all of the reports saved in that version of PBI Desktop.
To me the behavior makes sense as there are features in the newer versions that the earlier versions would have to "predict" in order to support.

I must have misspoke. I cannot open reports created in the October 2018 version with the NEW November 2018 version. Failure of backward compatibility is not something I usually expeience with MSFT products. In our case it appears to be those reports that used Direct Query. The error throws when the report is attempting to load the data.
