Release Highlight

The type error with $addToSet in bulkWrite was fixed

Previously the following code sample would show a type error:

interface IndexSingatureTestDocument extends Document {
    readonly myId: number;
    readonly mySet: number[];
  }
const indexSingatureCollection = undefined as unknown as Collection<IndexSingatureTestDocument>;
indexSingatureCollection.bulkWrite([
  {
    updateOne: {
      filter: { myId: 0 },
      update: {
        $addToSet: { mySet: 0 } // The type error! Type 'number' is not assignable to type 'never'.
      }
    }
  }
]);

It happened because the driver's Document type falls back to any, and internally we could not distinguish whether or not this assignment was intentional and should be allowed.

After this change, users can extend their types from Document/any, or use properties of any type and we skip the $addToSet validation in those cases.
