Hello Chefs!

We have selected 12.18.31 as our Chef v12.18 release candidate which is scheduled for release on Monday January 23, 2017.

_Correction: The original post stated that 12.18.39 was the release candidate but this was incorrect. 12.18.31 is the correct version._

# Release Highlights

## Highlighted enhancements for this release:

- You can now specify the acceptable return codes from the chocolatey\_package resource using the returns property.
- You can now enable chef-client to run as a scheduled task directly from the client MSI on Windows hosts.

## Highlighted bug fixes for this release:

- Fixed exposure of sensitive data of resources marked as sensitive inside Reporting. Before you  
were able to see the sensitive data on the Run History tab in the Chef Manage Console. Now we  
are sending a new blank resource if the resource is marked as sensitive, this way we will not  
compromise any sensitive data.

## New deprecations introduced in this release:

### Chef::Platform Helper Methods

- **Deprecation ID** : 13
- **Remediation Docs** : [https://docs.chef.io/deprecations\_chef\_platform\_methods.html](https://docs.chef.io/deprecations_chef_platform_methods.html)
- **Expected Removal** : Chef 13 (April 2017)

### run\_command Helper Method

- **Deprecation ID** : 14
- **Remediation Docs** : [https://docs.chef.io/deprecations\_run\_command.html](https://docs.chef.io/deprecations_run_command.html)
- **Expected Removal** : Chef 13 (April 2017)
