Apache CloudStack 4.3.0 is out with an enhanced UI and new color theme!!!
For those upgrading from 4.2.1 to 4.3.0, the official upgrade instructions are at http://docs.cloudstack.apache.org/projects/cloudstack-release-notes/en/latest/rnotes.html#upgrade-from-4-2-x-to-4-3.
Some additional notes for upgrading while upgrading from 4.2.1 to 4.3 in a CentOS6 environment:
- The upgrade instructions require a yum upgrade cloudstack-management which pulls in newer versions of cloudstack-common, cloudstack-awsapi and cloudstack-management. Ensure you also run yum upgrade cloudstack-usage cloudstack-cli to pull in newer versions of these packages
- After the upgrade, the browser cache had to be cleared before the new UI theme started rendering correctly
- Console access stopped working after the upgrade. This was fixed by setting consoleproxy.url.domain to empty and secstorage.encrypt.copy to false followed by a SSVM and CPVM stop/start cycle and a management-server restart. See this mailing list discussion
A complete list of new features is available at http://docs.cloudstack.apache.org/projects/cloudstack-release-notes/en/latest/about.html
