The following new features have been added to the RightScale Cloud Management Platform. Be sure to read the documentation, follow best practice principles, and thoroughly test any new functionality before making any changes to your production deployment.
The Dashboard UI now supports the ability to perform a diff and compare two ServerTemplates, similar to the functionality that already exists for RightScripts. The resultant window displays the two specified templates in parallel with colored text highlights of all removed and modified attributes.
To learn more, see Differentiate Two ServerTemplates. (3423)
You now have the ability to run a script on some or all servers in an array. Instead of manually executing a script on each server in an array, you can now execute scripts at the server array level. This feature is especially useful for updating code on all the application servers in the array. You can either run the script on all servers or run a script on one server for testing purposes and then run it on the remaining servers.
To learn more, see Run a Script on Servers in a Server Array.
You now have the ability to run any RightScript on a running server. When a server is operational, under the Scripts tab, you can use the "Any Script" option to select any of the available RightScripts from a dropdown menu to run on the server.
To learn more, see Run 'Any Script' on a Server.
Changes to the software are listed here. Changes usually refer to enhancements to existing features, minor UI changes, additional logging or messaging, etc.
The Splunk implementation has undergone several changes that add functionality, improve the behavior, normalize the terminology and fix known issues. (3478)
Several improvements have been made to the RightScale API this release, including:
Several minor issues have been fixed with respect to the RightScale API. The API has undergone additional, more extensive testing during this release. Due to this hardening, RightScale is moving the API from "alpha" to "beta" status. (See the General Release Information for precise definitions of alpha and beta.) (3432)
Previously, you could only assign one security group to an instance. You can now assign multiple security groups to an instance for additional control and security.
To learn more, see Assign Multiple Security Groups to an Instance.
There is now a Collectd plugin that monitors the Apache log data. You can use this plugin to monitor some useful information from the Apache log file. For instance, you can set up an alert that will send an email notification if Apache related problems occur such as an increase in error status codes (4xx/5xx). This Apache Log monitoring plugin provides a good start for monitoring any data from your Apache log that is not included by default.
To learn more, see Collectd Plugin: Apache Log Monitor.
It use to be possible to inadvertantly include whitespace either before or after of a script's Input value. In some instances, this could cause the script to crash. This minor typo produced a fairly cryptic error message, making the mistake difficult to debug. The script Inputs form has been modified to do basic validity/error checking. If whitespace (space, tab, newline, form feed, etc.) is detected filling out a script's input, an immediate message is displayed next to the Input field in red:
"Warning! Input contains leading/trailing whitespace." (3665)
The following bugs have been resolved in this release.
Under certain instances, the Splunk Indexer Install script could hang and not finish processing. The script had a typo in it that caused permissions related issues with the CA.pem (default Certificate Authority) file. The fix has been applied and the new script has been pushed live. (2752w)
Previously, if a slave database was unable to contact the master, the slave would time out. However, the server would still enter the operational state. For example, this situation could occur, if the Security Group did not allow access. The boot and operational scripts have been fixed to produce an error message stating that the slave cannot communicate with the master. Further, the slave database will "strand" on boot and will no longer go to an "operational" state. (2778w)
There are no known unresolved issues.

New and significant changes for this release with respect to ServerTemplates and RightScripts are summarized below. New and updated ServerTemplates and RightScripts are typically released 2-5 days after the new release of the RightScale Cloud Management Platform. Updated status messages with respect to actual release date/time of the ServerTemplates and RightScripts will be found here within this document.

MySQL S3/EBS Toolbox
This new template is intended for service personnel and advanced users to perform maintenance, diagnostics, and recovery operations. This is a plain bare-bones MySQL template that only installs the necessary software requirements to set up a basic MySQL server. Once the server is operational, you can execute a variety of operational scripts to perform the desired operation, such as:
The following scripts have been modified to support Ubuntu:
Previously, the bundling feature did not work correctly on running instances in EC2-EU that were launched with one of our EC2-EU ServerTemplates. To fix the problem, a newer version of the ec2 ami tools (1.3-31780) was added to a our new AWS EU RightImages to support the bundling of instances in EC2-EU. If you have an instance that is using a previous version of our EU RightImages that does not support bundling, you can manually update the ec2 ami tools version by following the instructions on the FAQ: Cannot bundle AWS EU RightScale image.
Previously, there was some confusion about the "DB EBS master restore" RightScript. The script not only restores the EBS database, it also changes the DNS entry. Therefore, "DB EBS master restore" was renamed "DB EBS restore and become master." (2844w)
