The following message was emailed to SnapLogic org Admins on Monday, March 9th:
As of 4 PM PT today [March 9th], we have updated the default Form UI engine back to being an opt-in feature until the next release as we allow more time to collect and incorporate user feedback.
We have uncovered an issue in the HDFS reader/writer and in the SOAP Snap which is planned to be resolved this week. As such, we will be deferring the mandatory upgrade by one week to allow our customers some time to validate the HDFS/SOAP fixes in their environments. The Auto-Update will be deployed on March 21st, 9:00 PM PT.
