Chef Workstation 20.10.168 Released!

We are delighted to announce the availability of version 20.10.168 of Chef Workstation.

Security Updates

Ruby has been updated to 2.7.2, which includes a fix for CVE-2020-25613.


Install times on Windows systems are now 2.5x faster.

Chef Workstation Powershell Shortcut

We removed the administrator requirement from the PowerShell shortcut added to the Desktop on install. Users who desire this existing functionality should right-click and Run as administrator on this shortcut.

Chef Infra Client

Chef Infra Client has been updated from 16.5.77 to 16.6.14. This release adds support for Microsoft's pwsh (commonly known as PowerShell Core) in addition to its previous support for PowerShell. The powershell_script resource includes a new interpreter property that accepts either powershell or pwsh, the powershell_out and powershell_exec custom resource helpers have been updated with a new argument that accepts either :pwsh or :powershell, and the powershell_exec helper now supports the 32-bit version of Windows.

This release also improves the Target Mode feature by converting the majority of Ohai plugins to run remotely, adds a new chef_client_config resource, and fixes various bugs.


Cookstyle has been updated from 6.19.5 to 6.21.1. This release includes an updated RuboCop engine, improves scan times, fixes various bugs, and adds 3 new cops:


The Lint/RedundantSafeNavigation cop detects redundant save navigation operators in order to simplify code. For example attrs&.respond_to?(:[]) can be simplified to just attrs.respond_to?(:[]) because respond_to? will not error even if attrs is not defined.


The ChefCorrectness/OctalModeAsString cop detects mode properties that incorrectly use a string to represent an octal value. We highly recommend using strings that contain a base 10 mode value, but even if you want to use octal values, they can't be passed as strings.


The ChefDeprecations/UseYamlDump cop detects cookbooks that use the .to_yaml method. Chef Infra Client 16.5 introduced performance enhancements to Ruby library loading and due to the underlying implementation of Ruby's .to_yaml method, it does not automatically load the YAML library. We recommend using YAML.dump() instead, which is functionally equivalent, and also properly loads the YAML library.

Kitchen EC2

The kitchen-ec2 gem has been updated from 3.7.2 to 3.8.0. This release allows multiple IP addresses to be specified when creating a security group and fixes a bug when creating spot instances.

Kitchen Dokken

The kitchen-dokken gem has been updated from 2.11.0 to 2.11.1 This release improves how kitchen-dokken determines if containers are available for connections.


The knife-ec2 plugin has been updated from 2.0.4 to 2.0.6. This release fixes an error that would occur when using the --server-connect-attribute private_ip_address flag.
