| list-PREDICATE | |
| -------------- | |
| * The :command:`list(TRANSFORM)` command gained a new ``PREDICATE`` selector | |
| that invokes a user-defined :command:`function` to decide which elements are | |
| transformed. | |
| * The :command:`list(FILTER)` command gained a new ``PREDICATE`` mode | |
| that invokes a user-defined :command:`function` to decide which elements are | |
| included or excluded, complementing the existing ``REGEX`` mode. |
