— Jeff;

The Amazon Linux AMI is a supported and maintained Linux image for use on Amazon EC2.

We offer new major versions of the Amazon Linux AMI after a public testing phase that includes one or more Release Candidates. The Release Candidates are announced in the EC2 forum and we welcome feedback on them.

Launching 2015.09 Today

Today we announce the 2015.09 Amazon Linux AMI, which is supported in all regions and on all current-generation EC2 instance types. The Amazon Linux AMI supports both PV and HVM mode, as well as both EBS-backed and Instance Store-backed AMIs.

You can launch this new version of the AMI in the usual ways. You can also upgrade an existing EC2 instance by running the following commands:

$ sudo yum clean all $ sudo yum update

And then rebooting the instance.

New Kernel

A major new feature in this release is the 4.1.7 kernel, which is the most recent long-term stable release kernel. Of particular interest to many customers is the support for OverlayFS in the 4.x kernel series.
