After my blog post explaining our technical choices for Sulu 2.0 we have decided that it is the right time to make a first alpha release although quite some functionality is still under development. You should see it more as a developer preview in order to retrieve feedback from you. Please tell us about any bugs you might encounter and anything that is missing in our UPGRADE.md file.
The most important entities already have a list and a form, so the most basic functions can now be tested. The old administration interface is gone, so from now on the new admin is accessible on the URL "/admin" - not anymore on "/admin/v2" for those of you who have already played around with our develop branch.
There is also the ExampleEventBundle which showcases how easy it is to display a simple list with an edit form for an existing API. This bundle will also be the example for the further instructions on how to extend our administration interface.
The single steps have separate Pull Requests in the ExampleEventBundle which will be linked in the text below. They start from a point where an API is already available. The API was built with an interesting architecture using a CommandBus, but that's the topic of a separate blog post.
