Amazon DocumentDB (with MongoDB compatibility) released version 8.0.3 on Nov 10, 2026. The update adds hybrid post‑quantum TLS that uses ML‑KEM key exchange when the client supports it, letting you protect data in transit against future quantum attacks. It also introduces wildcard indexes for dynamic schemas and a $unionWith aggregation stage to combine collections in a single query. The changes are live in every AWS Region that offers DocumentDB.

## The facts
