Clojurians Log v2

The new Duct is now in beta. I decided against changing all the libraries to a common "1.0.0-beta1" version, as it's likely they'll need to update individually while bugs are sorted out. The documentation on Duct is at: https://duct-framework.github.io/ The docs provide an overview of the system, and how to get started in using Duct to write web applications. Over the next few weeks I'll be adding a "Development" section that will go into detail on the options you have for developing and debugging Duct applications. CIDER integration is already operational via the --init-cider option, and Calva integration is next on the list. I don't anticipate any breaking changes at this point before stable release, but testing might reveal things that need altering.
