Ohai Chefs!
We’re happy to announce the release of Chef v13.7!
# Release Highlights
## The `windows_task` Resource should be better behaved
We’ve spent a considerable amount of time testing and fixing the `windows_task` resource to ensure that it is properly idempotent and correct in more situations.
## Credentials handling
Previously, chef on the workstation used `knife.rb` or `config.rb` to handle credentials. This didn’t do a great job when interacting with multiple Chef servers, leading to the need for tools like `knife_block`. We’ve added support for a credentials file that can contain configuration for many Chef servers (or organizations), and we’ve made it easy to indicate which account you mean to use.
## New deprecations
### `erl_call` Resource
We introduced `erl_call` to help us to manage CouchDB servers back in the olden times of Chef. Since then, we’ve noticed that no-one uses it, and so `erl_call` will be removed in Chef 14. Foodcritic rule FC105 has been introduced to detect usage of erl\_call.
### epic\_fail
The original name for the ignore\_failure property in resources was epic\_fail. Our documentation hasn’t referred to epic\_fail for years and out of the 3500 cookbooks on the Supermarket only one uses epic\_fail. In Chef 14 we will remove the epic\_fail property entirely. Foodcritic rule FC107 has been introduced to detect usage of epic\_fail.
### Legacy Mixins
In Chef 14 several legacy legacy mixins will be removed. Usage of these mixins has resulted in deprecation warnings for several years. They were traditionally used in some HWRPs, but are rarely found in code available on the Supermarket. Foodcritic rules FC097, FC098, FC099, FC100, and FC102 have been introduced to detect these mixins.
- Chef::Mixin::LanguageIncludeAttribute
- Chef::Mixin::RecipeDefinitionDSLCore
- Chef::Mixin::LanguageIncludeRecipe
- Chef::Mixin::Language
- Chef::DSL::Recipe::FullDSL
### :uninstall action in chocolatey\_package
The chocolatey cookbook’s chocolatey\_package resource originally contained an :uninstall action. When chocolatey\_package was moved into core Chef we made :uninstall an alias for :remove. In Chef 14 :uninstall will no longer be a valid action. Foodcritic rule FC103 has been introduced to detect the usage of the :uninstall action.
## Bugfixes
- Resolved a bug where knife commands that prompted on Windows would never display the prompt
- Fixed hiding of sensitive resources when converge\_if\_changed was used
- Fixed scenarios where services would fail to start on Solaris
## Security Updates
- OpenSSL has been upgraded to 1.0.2n to resolve CVE-2017-3738, CVE-2017-3737, CVE-2017-3736, and CVE-2017-3735.
- Ruby has been upgraded to 2.4.3 to resolve CVE-2017-17405

If you need an ARM build, here you go:
> **[Chef 13 on the BeagleBone Black UPDATED X4](https://leastresistance.wordpress.com/2017/05/12/chef-13-on-the-beaglebone-black/)**
>
> Now that the Chef client 13 is available, I decided to upgrade my ARM build to the latest release. ARM is still not officially supported, but building was fairly straightforward. I had Chef 12.17.1…
