Morepath 0.4 and breaking changes

I've just released Morepath 0.4!

Morepath 0.4 is a Python web framework that's small ("micro") and packs a lot of power. There are a lot of facilities for application reuse. And as opposed to most web frameworks, it actually has some intelligence about generating hyperlinks to objects.

Morepath 0.4 has a breaking change to the way application reuse works. Don't worry, you can fix your code by making a few minor changes. In short, Morepath application objects are now classes, not instances, and you can instantiate this class to get a WSGI object. See the CHANGES for a lot of details on what happened and what you need to do.

The big win is that application reuse in Morepath has become Python subclassing, and that making a WSGI application (even a parameterized one) is just instantiating the class.

The other win is that Morepath gained even more extensibility features, namely the ability for Morepath extension to introduce new Morepath directives (the decorators you see everywhere in Morepath examples). But I can't talk too much about that until I document them properly.

Along with the new Morepath, I've also made the initial release of BowerStatic (announcement). BowerStatic is the WSGI framework that lets you easily include bower-installed resources in your web page and do the right thing with caching (forever, thank you, but on a separate URL for each version).

How does that relate to Morepath, you may ask? Well, today I've also released the Morepath integration for BowerStatic, more.static. I've described in the Morepath documentation what to do to get it working in your Morepath project. The reason Morepath 0.4 had the breaking change was in part to support more.static, which needed the ability to introduce a new Morepath directive among other things.
