There isn't really a "development" version and a "release" version of trusty. Once trusty was released, ISO images were created and there was much hoopla, but the installation sources for users testing trusty pre-release don't need to be modified post-release to do anything differently.
If your apt sources (see /etc/apt/sources.list* files and directory) specify lines like this: deb http://mirror-name/ubuntu/ trusty main deb http://mirror-name/ubuntu/ trusty-updates main deb http://security.ubuntu.com/ubuntu/ trusty-security main then you simply need to run sudo apt-get update && sudo apt-get -u dist-upgrade to ensure you're fully up-to-date for all security issues and reliability issues.
