+# What's New in 16.6
+
+## pwsh Support
+
+We've updated multiple parts of the Chef Infra Client to fully support Microsoft's `pwsh` in addition to our previous support for `PowerShell`.
+
+### powershell_script resource
+
+The `powershell_script` resource includes a new `interpreter` property that accepts either `powershell` or `pwsh`.
+
+```ruby
+powershell_script 'check version table' do
+  code '$PSVersionTable'
+  interpreter 'pwsh'
+end
+```
+
+### powershell_out / powershell_exec helpers
+
+The `powershell_out` and `powershell_exec` helpers for use in custom resources have been updated to support `pwsh` with a new argument that accepts either `:pwsh` or `:powershell`
+
+```ruby
+powershell_exec('$PSVersionTable', :pwsh)
+```
+
+## Enhanced 32bit Windows Support
+
+The `powershell_exec` helper now supports 32bit Windows. This ensures many of the newer PowerShell based resources in Chef Infra Client will function as expected on 32bit systems.
+
+## New Resources
+
+### chef_client_config
+
+The `chef_client_config` resource allows you to manage Chef Infra Client's `client.rb` file without the need for the `chef-client` cookbook.
+
+#### Example
+
+```ruby
+chef_client_config 'Create client.rb' do
+  chef_server_url 'https://chef.example.dmz'
+end
+```
+
+#### chef-client Cookbook Future
+
+With the inclusion of the `chef_client_config` resource in Chef Infra Client 16.6, it is now possible to fully manage the Chef Infra Client without the need for the `chef-client` cookbook. We highly recommend using the `chef_client_config`, `chef_client_trusted_certicate`, and `chef_client_*` service resources to manage your clients instead of the `chef-client` cookbook. In the future we will mark that cookbook as deprecated, at which time it will no longer receive updates.
+
+Here's a sample of fully managing Linux hosts with the built-in resources
+
+```ruby
+chef_client_config 'Create client.rb' do
+  chef_server_url 'https://chef.example.dmz'
+end
+
+chef_client_trusted_certificate "chef.example.dmz" do

+
+## Updated Resources
+
+### ifconfig
+
+The `ifconfig` resource has been updated to no longer add empty blank lines to the configuration files. Thanks for this improvement [@jmherbst](https://github.com/jmherbst/)!
+
+### windows_audit_policy
+
+The `windows_audit_policy` resource has been updated to fix a bug on failure-only auditing
+
+## Ohai Improvements
+
+### Passwd Plugin For Windows
+
+The optional Ohai `Passwd` plugin now supports Windows hosts in addition to Unix-like systems. To collect user/group data on Windows hosts you can use the `ohai_optional_plugins` property in the new `chef_client_config` resource to enable this plugin.
+
+```ruby
+chef_client_config 'Create client.rb' do
+  chef_server_url 'https://chef.example.dmz'
+  ohai_optional_plugins [:Passwd]
+end
+```
+
+Thanks for adding Windows support to this plugin [@jaymzh](https://github.com/jaymzh)!
+
+### Improved Azure Detection
+
+The `Azure` plugin has been improved to better detect Windows hosts running on Azure. The plugin will now look for DHCP with the domain of `reddog.microsoft.com`. Thanks for this improvement [@jasonwbarnett](https://github.com/jasonwbarnett/)!
+
+## Security
+
+Ruby has been updated to 2.7.2 which includes a fix for [CVE-2020-25613](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-25613).
