## Unprivileged Symlink Creation on Windows

Chef can now create symlinks without privilege escalation, which allows for the creation of symlinks on Windows 10 Creator Update.

## nokogiri Gem

The nokogiri gem is once again bundled with the omnibus install of Chef

## zypper_package Options

It is now possible to pass additional options to the zypper in the zypper_package resource. This can be used to pass any zypper CLI option

### Example

```ruby
zypper_package 'foo' do
  options '--user-provided'
end
```

## windows_task Improvements

The `windows_task` resource now properly allows updating the configuration of a scheduled task when using the `:create` action. Additionally the previous `:change` action from the windows cookbook has been aliased to `:create` to provide backwards compatibility.

## apt_preference Resource

The apt_preference resource has been ported from the apt cookbook. This resource allows for the creation of APT preference files controlling which packages take priority during installation.

Further information regarding apt-pinning is available via <https://wiki.debian.org/AptPreferences> and <https://manpages.debian.org/stretch/apt/apt_preferences.5.en.html>

### Actions

- `:add`: creates a preferences file under /etc/apt/preferences.d
- `:remove`: Removes the file, therefore unpin the package

### Properties

- `package_name`: name attribute. The name of the package
- `glob`: Pin by glob() expression or regexp surrounded by /.
- `pin`: The package version/repository to pin
- `pin_priority`: The pinning priority aka "the highest package version wins"

### Examples

Pin libmysqlclient16 to version 5.1.49-3:

```ruby
apt_preference 'libmysqlclient16' do
  pin          'version 5.1.49-3'
  pin_priority '700'
end
```

Unpin libmysqlclient16:

```ruby
apt_preference 'libmysqlclient16' do
  action :remove
end
```

Pin all packages from dotdeb.org:

```ruby
apt_preference 'dotdeb' do
  glob         '*'
  pin          'origin packages.dotdeb.org'
  pin_priority '700'
end
```
