With the new PIWI version a new classloader implementation is shipped. Classloading in PHP has become really nicely. I consider writing a blog entry later in time about my opininon in PHP classloading, but for now you have to check out the code itself.
Basically, classes can be automatically loaded into a cache. From there you’ll load it into your app. In return you get the chance not to write any include or require statements anymore. For my taste those are too static.
Besides that I started documentation, improved the web app structure and added some cool classes which are not necesary by the core, but useful to have.
