Thanks for reaching out to us! We have submitted the updated packages to AWS and the Lightsail platform, but they are still in the process of publishing them to the marketplace.
To get the latest version of all of our applications for AWS, we suggest that you use our Bitnami Launchpad for AWS. We publish the most up-to-date packages in our launchpad as soon as they are ready.
Just like the AWS Marketplace and Lightsail, the launchpad is free to use, so you won't need to pay for anything except the hosting of the applications.
As an alternative for Lightsail, you can launch a regular AWS Lightsail without any Bitnami application preconfigured and manually install a Bitnami NGINX Stack in that instance using the installer from our website
Note you will need to manually configure starting services on server boot using the guide below
Hope it helps,
