Upgrading to Amazon Linux 1 (AL1) version 2013.03
Please upgrade to Amazon Linux 1 (AL1) version 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 1 (AL1) 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 Amazon Linux 1 (AL1) through Amazon Premium Support may be asked to move to newer versions as part of the support process.
To upgrade to Amazon Linux 1 (AL1) version 2013.03.1 from 2011.09 or later, run yum update. When the upgrade is complete, reboot your instance.
New Features
Kernel 3.4.43
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 1 (AL1) version 2013.03.
OpenSSH 6.1
In response to customer requests, we have moved to OpenSSH 6.1 for this release of Amazon Linux 1 (AL1). This enables the configuration option of AuthenticationMethods for requiring multi-factor authentication.
OpenSSL 1.0.1
Also based on customer requests, we have updated OpenSSL to 1.0.1.
