Please verify that all users in your environment are on Google Chrome 68+. For more information, see Desktop Requirements.
Wrangling:
- In data grid, you can select multiple columns before receiving suggestions and performing transformations on them. For more information, see Data Grid Panel.

Function Name Description ARRAYINDEXOF Function Computes the index at which a specified element is first found within an array. Indexing is left to right.
ARRAYRIGHTINDEXOF Function Computes the index at which a specified element is first found within an array, when searching right to left. Returned value is based on left-to-right indexing.
ARRAYSLICE Function Returns an array containing a slice of the input array, as determined by starting and ending index parameters.
ARRAYMERGEELEMENTS Function Merges the elements of an array in left to right order into a string. Values are optionally delimited by a provided delimiter.

LIST*functions now accept Array type only inputs.
Changes to System Behavior
$filepath disabled
In a prior release, the $filepath reference was enabled in Trifacta Wrangler. Since all file paths are to the local desktop, this reference is considered unreliable. It has been disabled for use in this version and subsequent versions of the product.
NOTE: If your recipes contain references to $filepath in them, they are broken in the new version of the product. Please review your recipes in the Transformer Page to see if specific steps are broken.
Key Bug Fixes
None.
New Known Issues

| TD-38869 | Upload of Parquet files does not support nested values, which appear as null values in the Transformer page. Workaround: Unnest the values before importing into the platform. |

Changes to System Behavior
SOURCEROWNUMBER function generates null values consistently
The SOURCEROWNUMBER function returns the row number of the row as it appears in the original dataset. After some operations, such as unions, joins, and aggregations, this row information is no longer available.
Previously, the results were confusing. When source row information was not available, the function was simply not available for use.
Now, the behavior of the SOURCEROWNUMBER function is more consistent:
- If the source row information is available, it is returned.
- If it is not available:
- The function can still be used.
- The function returns null values in all cases.
For more information, see SOURCEROWNUMBER Function.
New Functions
| Function Name | Description |
|---|---|
| UNIQUE Function | Generates a new column containing an array of the unique values from a source column. |
