It is an open-source project with numerous development teams working in parallel creating various branches containing new and exciting features. The source code is organized using the Subversion version control system (SVN). SVN repositories are comprised of a trunk and branches. The Chameleon team keeps the trunk as the 'stable' version, whereas side-line or experimental development projects are done in branches.
The problem is some branches have features that other branches don't have, and many new features are still not merged into the trunk. While this is an inevitable side-effect of rapid open-source development, it creates some confusion for new users. The result of multiple branches not only increases the difficulty of choosing which version of the bootloader to use, but makes it impossible to support certain hardware.2
AsereBLN's bootloader is based on Chameleon 2.0. He simplified the source code to make it more reliable, stable and comprehensive.
This project is discontinued but not really outdated.
This version consolidates the best features from all of the available sources for maximum compatibility across platforms. We've decided to use the name Chimera to differentiate the project from the Chameleon trunk.The focus for Chimera is to support current, new, and future hardware, not to add legacy support for older hardware.3
