To keep up to date on images, check this page at Bitnami: https://bitnami.com/stack/dreamfactory/cloud/aws
Scroll down to the bottom of the page for launch links.
FYI, with Bitnami images and installers, launching a new instance like this or running the installer locally does not upgrade an existing stack but creates a new one. If you want to upgrade an existing stack you have to use instructions linked above.
