Hey everyone!

I hope everyone is having an excellent Friday and to make things a bit nicer we shipped a new release Cookstyle to help identify more deprecations between Chef Infra Client 12 and 13:

### 4 New Cops

#### ChefDeprecations/ChefShellout

The `ChefDeprecations/ChefShellout` cop detects the use of the `Chef::ShellOut` class, which was removed in Chef Infra Client 13. It will autocorrect all occurrences to instead use `Mixlib::ShellOut`, which is a drop-in replacement.

`Enabled by default`: True

`Autocorrects`: Yes

#### ChefDeprecations/ExecutePathProperty

The `ChefDeprecations/ExecutePathProperty` cop detects `execute` resources that use the `path` property, which was removed in Chef Infra Client 13. To set a path for use when executing, you should instead set the `PATH` via the `environment` property.

`Enabled by default`: True

`Autocorrects`: No

#### ChefDeprecations/ExecuteRelativeCreatesWithoutCwd

The `ChefDeprecations/ExecuteRelativeCreatesWithoutCwd` cop detects the usage of the `execute` resource with a relative path in the `creates` property and with no `cwd` property present. This condition will fail in Chef Infra Client 13 or later, and it never would have actually worked, so it was always failing code. You should either provide an absolute path to the `creates` property, or use a relative path with `creates` and specify the working directory with `cwd`.

`Enabled by default`: True

`Autocorrects`: No

#### ChefDeprecations/WindowsPackageInstallerTypeString

The `ChefDeprecations/WindowsPackageInstallerTypeString` cop detects the usage of the `windows_package` resource with a `installer_type` property value that is a String. In Chef Infra Client 13 or later, this property value must be a Symbol.

`Enabled by default`: True

`Autocorrects`: Yes

### Other Improvements

- The `ChefDeprecations/DeprecatedPlatformMethods` cop now detects the usage of `Chef::Platform.set`, which was removed in Chef Infra Client 13.
- Several minor performance and memory usage improvements were made to speed up Cookstyle scans.
- An error was resolved that would occur when using Cookstyle with the `rubocop-ast` gem, version 0.4.0 or later.

Enjoy,
