### 02/21/220 - 616-8879 - Compute Update

- New feature: `[:db/retract eid aid]` will retract all values for an eid/aid combination.
- Critical Fix: regression introduced in 569-8835 where `datoms`, `seek-datoms`, and `index-range` return incorrect results if `Iterable.iterator` is called more than once on the returned value.
- Fix: respect `nil` as a limit in query `pull` expression.
- Fix: respect `false` as a default in query `pull` expressions for boolean-valued attributes.
- Fix: allow arbitrary `java.util.List` (not just Clojure vectors) for lookup refs.
