This release adds the ability to mix database backends (mongoDB and db3), improves MongoDB support (with automatic installation if needed), improves Twitter Bootstrap support and updates it to 2.0, improves the translation tool from the old to the new syntax, and adds hooks to register favicons.
This is mostly a bugfix release. There are some improvements to MongoDB, the email library, and Bootstrap widget, and a translation tool from old to new syntax has been added.
Support for Twitter's Bootstrap was added, providing a good baseline CSS for Opa projects. A new version of stdlib.widgets.hlist was included for displaying hierarchical lists. Session.cloud was fixed for the creation of Opa sessions distributed over many servers. The CouchDB API was included.
