Here's a quick development status of version 4.0.

- the runtime model is 75% functional. the remaining 25% is around extended functions like worfklow, content versioning
- the administrative model is about 20% complete.  A lot of the admin functions still be to be done, right now, I can get the module up and running but it requires some manual manipulation of the configuration and settings in the database.

An actual working instance of the module is now up and running on gooddogs.com
http://www.gooddogs.com/dotnetnuke/Downloads/tabid/100/i/-1/v/8/Default.aspx

It is now being used for file downloads.
I am in the process of recording a video blog walking you through some of the new capabilities of the module as demonstrated on gooddogs.com, and hope to post that later today or tomorrow. Some of the cool things to notice, multiple files associated with a single repository item and downloads tracked at the individual file level. Integrated ratings and comments ( behind the scenes this is really cool, each of these functions are implemented as repository custom controls, and will be packaged as part of a module developer's toolkit. That means that if you use the repository template engine for your own custom DotNetNuke module, you can implement integrated ratings and comments as simply as adding [ToolKit.Comments] or [TookKit.Ratings] to your template, and with zero coding, implement them within your module)

STILL TO DO

1. runtime model
   1. Content versioning and history
   2.  workflow
2. administrative model
   1. form designer
   2. workflow designer
   3. storage designer
   4. repository application packager and installer

So, if you have a minute, go to the link above and check it out. As always, I really appreciate any feedback or comments.  .. .and look for a more detailed walkthrough of the module and it's status in a video blog to be posted soon in my blog.

Thanks!!

Your work is very valuable to all of us! Thank you!
