Any version of the Ascender Operator will work with Ascender 25.3.2 and beyond. That is when we swapped to Valkey and thus needed to create the operator instead of using the AWX operator. Before that, you must use the AWX Operator.
That being said, we have been debating changing the versioning on the operator to exactly match the released Ascender version. Then just do new releases of the operator every time we release Ascender, whether we changed anything in the operator or not. This would keep things simple and not require a matrix.
