Our application breaks using the newest driver. See bug report here:
https://developercommunity.visualstudio.com/t/BCP-Problem-since-MSODBCDriver-18611/11020857

Unfortunately some of our customers are using windows auto updates for those drivers, and it broke some production environments.. just days before the holidays...

  I see the repro is for Windows. 18.6.1.1 wasn't released to Microsoft Update, so there shouldn't have been any auto-update mechanism on Windows in play there, unless it's something the customers initiated themselves. Regardless, though, if there is a bug there, we'll need to fix it. Thanks for the heads up.
