 # Upgrade to 2.9
 
+## Deprecated `Statement::fetchColumn()` with an invalid index
+
+Calls to `Statement::fetchColumn()` with an invalid column index currently return `NULL`. In the future, such calls will result in a exception.
+
 ## Deprecated `Configuration::getFilterSchemaAssetsExpression()`, `::setFilterSchemaAssetsExpression()` and `AbstractSchemaManager::getFilterSchemaAssetsExpression()`.
 
 Regular expression-based filters are hard to extend by combining together. Instead, you may use callback-based filers via `::getSchemaAssetsFilter()` and `::getSchemaAssetsFilter()`. Callbacks can use regular expressions internally.
