There's a big difference between AWS Aurora and AWS RDS PG. Both are managed services.

Amazon supports PG 12 and 13 is in beta. Aurora is Amazon's fork of Postgres which has different storage and replication so will always be behind.

A year doesn't sound too bad I think MySQL 8 has been generally available since april 2018 from Oracle

Honestly I don't know if they're even working on MySQL 8 for Aurora MySQL
