Thank you for your interest in CloudPanel! I have released the new version 3.1.0034 which includes new enhancements and bug fixes. If you run into any issues please be sure to post to the forums.
If you are upgrading from 3.0 you need to still apply 3.1 RC and then upgrade to the latest 3.1 after that. If this is a brand new environment you can always start from the latest CloudPanel version!
Please be sure to backup your environment before upgrading and if you run into any issues be sure to post it to the support forums.
