Please upgrade to Amazon Linux AMI 2013.03.1 from earlier versions.

While older versions of the AMI and its packages will continue to be available for launch in Amazon EC2 even as new Amazon Linux AMI versions are released, we encourage users to migrate to the newer versions of the AMI, and to keep their systems updated. In some cases, customers seeking support for an older version of the Amazon Linux AMI through Amazon Premium Support may be asked to move to newer versions as part of the support process.

To upgrade to Amazon Linux AMI 2013.03.1 from 2011.09 or later, run yum update. When the upgrade is complete, reboot your instance.

We have upgraded the kernel to version 3.4.43 which is part of the long-term stable release 3.4 kernel series. This replaces the 3.4.37 kernel that shipped with the initial Amazon Linux AMI 2013.03.

In response to customer requests, we have moved to OpenSSH 6.1 for this release of the Amazon Linux AMI. This enables the configuration option of AuthenticationMethods for requiring multi-factor authentication.

Also based on customer requests, we have updated OpenSSL to 1.0.1.

We are excited to include the Developer Preview of the new AWS Command Line Interface. The aws-cli tool is written in Python, and provides a one-stop-shop for controlling multiple AWS services through the command line.

Many of the packages in the AMI have been re-synced to their latest upstream version. For reference, we have produced a list of all source RPMs included in Amazon Linux AMI 2013.03. Here are some noteworthy additions and updates since the 2012.09.0 Amazon Linux AMI release:

The Amazon Linux AMI FAQs is updated with both general and technical topics.
