This topic includes Amazon Linux 1 (AL1) release notes updates for the 2014.09 release.

Upgrading to Amazon Linux 1 (AL1) version 2014.09

Please upgrade to Amazon Linux 1 (AL1) version 2014.09 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 latest version 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 Support may be asked to move to newer versions as part of the support process.

To upgrade to Amazon Linux AMI 2014.09 from 2011.09 or later, run sudo yum update. When the upgrade is complete, reboot your instance.

Remember that the Amazon Linux 1 (AL1) repository structure is configured to deliver a continuous flow of updates that allow you to roll from one version of Amazon Linux 1 (AL1) to the next. Please consult our lock-on-launch FAQ for a discussion of how you can lock an instance (either a new launch or already running) to a particular version of the Amazon Linux 1 (AL1) repositories.

New features

New AMI flavors since our last major release

We introduced GP2-by-default AMIs as part of our 2014.03.2 release, and they are included in our 2014.09 release.

Kernel 3.14

Having spent the past release tracking the 3.10 kernel series, for this release we have moved the kernel to version 3.14.19, which is the most recent long-term stable release kernel.

Additionally, instances running the HVM AMIs will now restart 30 seconds after a kernel panic, instead of hanging indefinitely.

Customers who depend on the previous HVM AMI behavior to remove faulty hosts from their fleet can adjust the kernel.panic setting by creating a new file /etc/sysctl.d/99-override.conf with kernel.panic=0 as the contents.

PV AMIs have always restarted on kernel panic.

Ruby 2.1

While Ruby 2.0 remains our default Ruby interpreter, we have added ruby21 packages to this Amazon Linux 1 (AL1) release.

Also, we have updated all of our versions of Ruby to newer upstream patch levels:

Java 8

While Java 7 is still the default on the AMI, OpenJDK 1.8 is included in the repositories with the java-1.8.0-openjdk package name.

Tomcat 8

Based on customer requests, we have added tomcat8 to the Amazon Linux 1 (AL1) repositories.

Also, we have updated all of our versions of Tomcat to the most recent upstream releases:

PostgreSQL 9.3

Numerous customers have asked for PostgreSQL 9.3, and it is now available in our Amazon Linux 1 (AL1) repositories as a separate package from PostgreSQL 9.2.

PostgreSQL 9.3 is specifically named postgresql93 and the 2014.09 release of Amazon Linux 1 (AL1) includes PostgreSQL 9.3.5.

Running yum install postgresql9 or yum install postgresql92 will still install PostgreSQL 9.2.

Docker 1.2

After a truly spectacular number of customer requests, we introduced Docker in the 2014.03 release of Amazon Linux 1 (AL1). With this release, we continue to track upstream development closely.

nginx 1.6

Also based on customer requests, this release of Amazon Linux 1 (AL1) comes with Nginx 1.6.1.

git 2

With the 2014.09 release of Amazon Linux 1 (AL1), we've moved from Git 1.8 to Git 2.1. Users upgrading from older releases will move directly from the older git to the newer.

PHP updates

We have updated all of our PHP packages to newer upstream versions:

New Packages

In addition to the features above, here are some other new packages added to our repositories, based on customer requests:

Fresh Packages

Many of our packages have been re-synced to their latest upstream version.

Some of the more popular package updates are:

AWS tools

We have included updated versions of many AWS command line tools. If there is an additional AWS tool that you would like, please call it out!

Discontinued packages

We have discontinued support for Python 2.4, GCC 4.6, and GCC 4.7 in this Amazon Linux 1 (AL1) release.

Supported Instance Types

There are six different flavors of Amazon Linux 1 (AL1) version 2014.09. This compatibility table shows which 2014.09 AMIs launch on each Amazon EC2 instance type.

Looking ahead to our 2015.03 release

We are planning on deprecating several of our AMI flavors with the 2015.03 release, as follows:
