Ohai Chefs!

We have selected 13.6.0 as our Chef v13.6 release candidate which is scheduled for release on Monday October 30, 2017.

# Release Highlights

## `deploy` Resource Is Deprecated

The `deploy` resource (and its alter ego `deploy_revision`) have been deprecated,  
to be removed in Chef 14. This is being done because this resource is considered  
overcomplicated and error-prone in the modern Chef ecosystem. A compatibility  
cookbook will be available to help users migrate during the Chef 14 release  
cycle. See [the deprecation documentation](https://docs.chef.io/deprecations_deploy_resource.html)  
for more information.

## zypper\_package supports package downgrades

`zypper_package` now supports downgrading installed packages with the  
`allow_downgrade` property.

## InSpec updated to 1.42.3

## Reserve certain Data Bag names

It’s no longer possible to create data bags named `node`, `role`,  
`client`, or `environment`. Existing data bags will continue to work as  
before.

## Properly use yum on RHEL 7

If both dnf and yum were installed, in some circumstances the yum  
provider might choose to run dnf, which is not what we intended it to  
do. It now properly runs yum, all the time.

## Ohai 13.6 Release Notes:

### Critical Plugins

Users can now specify a list of plugins which are `critical`. Critical plugins will cause Ohai to fail if they do not run successfully (and thus cause a Chef run using Ohai to fail). The syntax for this is:

```auto
ohai.critical_plugins << :Filesystem

```

### Filesystem now has a `allow_partial_data` configuration option

The Filesystem plugin now has a `allow_partial_data` configuration option. If set, the filesystem will return whatever data it can even if some commands it ran failed.

### Rackspace detection on Windows

Windows nodes running on Rackspace will now properly detect themselves as running on Rackspace without a hint file.

### Package data on Amazon Linux

The Packages plugin now supports gathering packages data on Amazon Linux

Please see the [CHANGELOG](https://github.com/chef/chef/blob/master/CHANGELOG.md) for the complete list of changes.
