## converge_if_changed Improvements

Chef Infra Client will now take into account any `default` values specified in custom resources when making converge determinations with the `converge_if_changed` helper. Previously, default values would be ignored, which caused necessary changes to be skipped. Note: This change may cause behavior changes for some users, but we believe this original behavior is an impacting bug for enough users to make it outside of a major release. Thanks [@ jakauppila](https://github.com/jakauppila) for reporting this.

## Bootstrap Improvements

Several improvements have been made to the `knife bootstrap` command to make it more reliable and secure:

- File creation is now wrapped in a umask to avoid potential race conditions
- `NameError` and `RuntimeError` failures during bootstrap have been resolved
- `Undefined method 'empty?' for nil:NilClass` during bootstrap have been resolved
- Single quotes in attributes during bootstrap no longer result in bootstrap failures
- The bootstrap command no longer appears in PS on the host while bootstrapping is running

## knife supermarket list Improvements

The `knife supermarket list` command now includes two new options:

- `--sort-by [recently_updated recently_added most_downloaded most_followed]`: Sort cookbooks returned from the Supermarket API
- `--owned_by`: Limit returned cookbooks to a particular owner

## Updated Resources

### chocolatey_package

The `chocolatey_package` resource no longer fails when passing options with the `options` property. Thanks for reporting this issue [@kenmacleod](https://github.com/kenmacleod).

### kernel_module

The `kernel_module` resource includes a new `options` property, which allows users to set module specific parameters and settings. Thanks [@ramereth](https://github.com/ramereth) for this new feature.

Example of a kernel_module resource using the new options property:

```ruby
  kernel_module 'loop' do
  options [ 'max_loop=4', 'max_part=8' ]
  end
```

### remote_file

The `remote_file` resource has been updated to better display progress when using the `show_progress` resource. Thanks for reporting this issue [@isuftin](https://github.com/isuftin).

### sudo

The `sudo` resource now runs sudo config validation against all of the sudo configuration files on the system instead of only the file being written. This allows us to detect configuration errors that occur when configs conflict with each other. Thanks for reporting this issue [@drzewiec](https://github.com/drzewiec).

### windows_ad_join

The `windows_ad_join` has a new `:leave` action for leaving an Active Directory domain and rejoining a workgroup. This new action also has a new `workgroup_name` property for specifying the workgroup to join upon leaving the domain. Thanks [@jasonwbarnett](https://github.com/jasonwbarnett) for adding this new action.

Example of leaving a domain

```ruby
windows_ad_join 'Leave the domain' do
  workgroup_name 'local'
  action :leave
end
```

### windows_package

The `windows_package` resource no longer updates environmental variables before installing the package. This prevents potential modifications that may cause a package installation to fail. Thanks [@jeremyhage](https://github.com/jeremyhage) for this fix.

### windows_service

The `windows_service` resource no longer updates the service and triggers notifications if the case of the `run_as_user` property does not match the user set on the service. Thanks [@jasonwbarnett](https://github.com/jasonwbarnett) for this fix.

### windows_share

The `windows_share` resource is now fully idempotent by better validating the provided `path` property from the user. Thanks [@Happycoil](https://github.com/Happycoil) for this fix.
