Why can DataVision find my database columns any more?
As of 0.6.0, table and column names in DataVision are case-sensitive. See Database Name Case Sensitivity for details. From versions 0.7.3 through 0.7.5, there was a bug that prevented tables from loading their column desriptions under certain circumstances. You would see tables in the report, but any tables not in the report would not load their columns properly when you tried to see their columns in the Field Picker window.
