Rob Allen has a new post about the tagging of the first beta of Slim Framework v3, the popular PHP microframework's latest version. In it he details a few of the major changes and requests help testing.

Last night, I tagged beta 1 of Slim Framework 3! This is a significant upgrade to v2 with a number of changes that you can read on the Slim blog. For me, the two key features that I'm most excited about are: PSR-7 support, [...and a] dependency injection container with container-interop compliance. [...] There's lots of other changes and we believe we have kept to the key tenants of Slim, keeping it focussed as a micro-framework suitable for building any application that you want to build.

He includes everything you'll need to test this newly tagged release with the help of his skeleton application. He also links to the new documentation that's a work in progress to replace the current set of docs. You can find more information on the full list of changes over on the Slim blog.
