We're really excited to have released Chef 11!

This release includes a new Erlang based server which operates at great scale. Cycle Computing recently ran over 10,000 nodes against one Chef 11 server. [1]

The client will continue to be Ruby, and has many improvements itself, including:

- many windows improvements
- partial templates
- chef-apply, a tool to run a single cookbook against a system
- run list based cookbook file evaluation order
- substantial improvements on node attributes and precedence handling

You can read the release notes here: [http://bit.ly/WM2EW2](http://bit.ly/WM2EW2)

You can download both the client and the server at [http://www.opscode.com/chef/install](http://www.opscode.com/chef/install)

We also announced Facebook's use of Chef today. They will be speaking at ChefConf, if you're interested in operating infrastructure at huge scale, it's a talk you don't want to miss.

Any information on how to migrate from chef server 10.x to 11?

I only see enterprise linux and ubuntu for chef server is that no package  
for debian for this?

Jeff, thanks for asking, we'll update the release notes to be more  
specific about the Windows work, which spanned a range of changes from  
fixing log output to improving performance of chef-client on the Windows  
platform.

A bigger bang piece of work is the new registry\_key resource  
([registry\_key Resource](http://docs.opscode.com/resource_registry_key.html)) that lets you  
manipulate the registry without including the Windows cookbook. A nice new  
feature there is the ability to control the registry's architecture  
through the :architecture attribute -- automation tasks often need  
explicit control over reading / writing to / from the 32-bit or 64-bit  
view of the registry, and that's what this resource gives you.

You can do so much on \*nix platforms with core resources, and I personally  
like being able to have more of that experience on Windows.

-Adam

My first guess is that qpidd is running.

Try

sudo service qpidd stop  
sudo chkconfig qpidd off

Then re-run Chef.

The most recent patchlevel of the Chef Server is 11.0.4, which includes these important fixes:

CHEF-3818 - chef-server-webui is susceptible to recent Rail’s YAML exploit  
CHEF-3813 - Server does not return cookbook dependencies in metadata

The latest version of the packages is available at [http://www.opscode.com/chef/install](http://www.opscode.com/chef/install)

Not yet, we're planning on providing tools to help with the data  
migration and will be working on that soon.

We're only releasing packages for the systems we're testing and  
verifying now. I don't have a date for debian support, it will likely  
be based on demand. However I have installed the packages for Ubuntu  
on Debian 6.0.6 and I've seen others say that it worked for them as  
well.

The Chef 11 client will be. I've done a little testing and it looks  
like it will work fine. We're looking to see what community support  
there is for building server packages and what demand there is.  
Omnibus is the official way forward for Opscode, and Omnibus does come  
in a deb format. If folks want packages that are distribution policy  
compliant, we're looking for that distribution's community to help  
produce them.
