Hi All, I’m excited to start using the new extensions stuff to get some new sites up, and hopefully convert some older ones. Before I get too far, I was wondering if there is still any reason to work off the metal branch, since the 0.6.0 candidate was just released. When I went to create a test extension, I noticed that script/generate is missing from my radiant site directory, so maybe I need metal to develop extensions? thanks! christian. ---

The release candidate gem was built from the mental branch. The reason script/generate isn’t included is that the generators aren’t completely supported in instance mode. We should rectify this though. If people are creating extensions it would be nice to be able to do it in instance mode. – John L. [http://wiseheartdesign.com](http://wiseheartdesign.com) ---

Apparently, I am using application mode of deployment, but is there a best know method as when to deploy using application mode versus instance mode? What are the pros/cons of each? ---

Instance mode is for when you want to install multiple radiant sites on the one server and keep them all at the same version. Dan. ---
