Chameleon has undergone many interface and back-end changes since its last release (version 3.3.184). The most significant change was made to the installation directory structure. Although some changes to Chameleon's directory structure are transparent, it is very important that you carefully read through this entire section before you upgrade Chameleon in either your development or production environment. This ensures that you are well aware of any issues specific to your environment before upgrading.
For detailed information about all the Chameleon changes since its last release, please see the Chameleon Change Log.
