    controller value to an array of strings.  [GH-9574]

    have to define them in a `post-processors` block. [GH-9638]

    work fine); the work to fix them is minimal and documented in GH-5810.
    [GH-5810]
* builder/amazon: The `ssh_private_ip` option has been removed. Instead, please
    use `"ssh_interface": "private"`. A fixer has been written for this, which

    previous buggy behavior, so it's worth ensuring your configuration is
    correct. [GH-5426]

    parse out components of a template.
* Packer will detect its own crashes (always a bug) and save a "crash.log"

    templates.

### FEATURES:

* **User Variables** allow you to specify variables within your templates
    that can be replaced using the command-line, files, or environmental
    variables. This dramatically improves the portability of packer templates.
    See the documentation for more information.
* **Machine-readable output** can be enabled by passing the
    `-machine-readable` flag to _any_ Packer command.

    resulting AMIs modified, such as access permissions and product codes.

### IMPROVEMENTS:

* You can now log to a file (instead of just stderr) by setting the
    `PACKER_LOG_FILE` environmental variable. [GH-168]
