The updates described are either important (where you need to take action) or of interest (you might want to know about these changes but you don't need to do anything).
Minor: Engine Yard stack upgrade
August 28th, 2012
Action: You automatically apply these changes the next time you click the Upgrade button for your environment.
- Fixes issue with PostgreSQL monitoring script.
- Fixes issue with Node.js log location. (Node.js is in Limited Access.)
During QA testing, we discovered that the `sshd reload' command does not perform syntax checking of the sshd config file. This resulted in the sshd process dying, thereby cutting off ssh access. We consequently decided to retain the current behavior (`ssh restart').

Limited Access: Support for High I/O Quadruple Extra Large (64-bit) instances
August 7th, 2012
Action: This is an optional Limited Access release. No action required. If you want to use the feature, you must click Upgrade on your environment.
Engine Yard Cloud customers can now use the new Amazon EC2 instance type, which provides very high, low latency, disk I/O performance. High I/O instances are ideal for high performance clustered databases and especially NoSQL databases like MongoDB.
If you would like to participate in this limited access release, submit a ticket with Engine Yard Support.
For more information about Engine Yard Cloud support for High I/O, see the Engine Yard Blog.
Note: Amazon currently provides support for three Availability Zones in the US East (N. Virginia) region, and in two Availability Zones in the EU West (Ireland) region.
Hotfix: Passenger 2 workers erroneously being culled by monitor process
August 2nd, 2012
Action: You automatically apply these changes the next time you click the Upgrade button for your environment.
Fixes Rails workers from being killed off incorrectly by the passenger monitor process under Passenger 2. (Passenger 3 is not affected.)
Limited Access: Add multiple instances to an environment at one time
August 2nd, 2012
Action: This is an optional Limited Access release. No action required. If you want to use the feature, you must click Upgrade on your environment.
Engine Yard Cloud customers can now add multiple application or utility instances to an environment at one time. (For database integrity reasons, you cannot add multiple database instances at once.)
Adding multiple instances at once means that you no longer need to serially add instances, waiting for separate Chef runs and cluster reconfiguration each time. This feature allows you the ability to scale quickly, as needed, based on your unique app and environment.
If you would like to participate in this limited access release, submit a ticket with Engine Yard Support.
For more information, see Add Instances to a Cluster.
