When Vapor connects your application to an RDS instance, it employs SSL certificate verification to encrypt the connection. If your RDS instance utilizes this Certificate Authority, you must update it to avoid potential connectivity interruptions after this date.
This version of Vapor Core includes a new certificate bundle, ensuring compatibility with the latest Certificate Authorities provided by AWS. Crucially, you must update Vapor Core before updating the database to guarantee that your application remains connected post-database update. Once Vapor Core is current, you're ready to update the Certificate Authority for the impacted databases.
