the lead developers of TurboGears have been in talks with the Pylons project to join forces with them and Repoze.BFG's developers as a new unified project called Pyramid. Due to the backward compatibility issues this move would have, and guaranteed TurboGears keeps being a reliable platform on long term, the current team decided to collaborate with the Pylons Project on everything possible but not to base the TurboGears core on Pyramid. Future development, Python 3 support and speed improvements have happened in the 2.3 branch which has seen a full rewrite of the TurboGears core while keeping it backward compatible with existing applications, since that release TurboGears had its own core instead of being based on the Pylons framework. During the 2.3 series the framework has been experimenting with a so-called "minimal mode" which makes it able to act as a micro-framework de facto reducing the dependencies from tens to just 3 and positioning TurboGears between Flask and Django in the rose of python frameworks for its objectives, as it aims as being able to scale from a micro-framework to a full-stack framework depending just on the fact that the TurboGears2 or the tg.devtools package is used. Since version 2.4 the framework has now a modular components based architecture, which allows users to enable and replace the components at their will, thus making TurboGears actually follow its mission of being a web framework that scales with users needs.
