Yesterday I published new stretch AMIs for Amazon EC2 for both arm64 and amd64 architectures. The AMIs refresh all package version to those included in Debian 9.9 (stretch), per the release announcement at https://www.debian.org/News/2019/20190427
The AMI details, as usual, are available at https://wiki.debian.org/Cloud/AmazonEC2Image/Stretch The corresponding update in the AWS Marketplace is still pending. I recommend using the AMIs listed on the above wiki, rather than using the Marketplace, for up-to-date images. noah
