Iowa 0.9.1 has been released. This release fixes a bug with the WEBrick demo, significantly streamlines the process of using WEBrick with Iowa, adds options for more precise cache control, adds the ability to generate content such as images inline in an application and ask Iowa to provide URLs that will access this generated content (thanks to David Naseby for the inspiration for this), and now allows bindings to be seperated from the code file and places in a .bnd file.
