* provisioner/shell-local: Windows inline scripts now default to being appended
    with ".cmd", fixing a backwards incompatibility in v1.2.5 [GH-6626]

    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

    characters no longer need to be escaped.[GH-5376]
* provisioner/file: We've made destination semantics more consistent across the

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

* provisioner/ansible: The "default extra variables" feature added in Packer
    v1.0.1 caused the ansible-local provisioner to fail when an --extra-vars
    argument was specified in the extra_arguments configuration option; this
    has been fixed. [GH-5335]
* provisioner/powershell: Regression from v1.1.1 forcing extra escaping of
    environment variables in the non-elevated provisioner has been fixed.
    [GH-5515] [GH-5872]

    processing. This allows you to extract artifacts from a packer builder and
    use them with other post-processors like compress, docker, and Atlas.

### IMPROVEMENTS:

* core: Packer plugins are now compiled into the main binary, reducing file
    size and build times, and making packer easier to install. The overall
    plugin architecture has not changed and third-party plugins can still be
    loaded from disk. Please make sure your plugins are up-to-date! [GH-2854]

    builder. This is useful for provisioners. [GH-2232]
* **New config function: `template_dir`**: The directory to the template
    being built. This should be used for template-relative paths. [GH-54]
* **New provisioner: shell-local**: Runs a local shell script. [GH-770]

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

* core: Remote command output containing '\r' now looks much better
    within the Packer output.
* builder/vmware: Fix issue with finding driver files. [GH-279]

    are now replaced with `{{timestamp}}`. Run `packer fix` to fix your
    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.
* All strings in a template are now processed for variables/functions,
    so things like `{{timestamp}}` can be used everywhere. More features will
    be added in the future.

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

### IMPROVEMENTS:

* builder/amazon/all: User data can be passed to start the instances. [GH-253]

    without a master.

    floppy disks when booting. This allows for unattended Windows installs.
* `packer build` has a new `-force` flag that forces the removal of
    existing artifacts if they exist. [GH-173]
* You can now log to a file (instead of just stderr) by setting the
    `PACKER_LOG_FILE` environmental variable. [GH-168]

    the VirtualBox builder to have the ability to be used completely offline.

### IMPROVEMENTS:

* core: If SCP is not available, a more descriptive error message
    is shown telling the user. [GH-127]
* shell: Scripts are now executed by default according to their shebang,
    not with `/bin/sh`. [GH-105]
