* **Future Scaffolding** This release contains a large number of no-op
    refactoring changes. The Packer team at HashiCorp is preparing to split the
    plugins and core to make it easier for our third party maintainers and
    community members to release and maintain plugins, just like HashiCorp did
    with the Terraform Core-Provider split. The Packer team is committed to
    making sure that this split is seamless for our users and for our community
    maintainers -- if you are a community maintainer, you may want to follow
    along with some of the work by looking at the
    [core-plugin-split github tag.](https://github.com/hashicorp/packer/pulls?q=is%3Apr+label%3Acore-plugin-split)
    No one needs to do anything, yet, but we felt it was worth calling out all
    the work that isn't making it into the changelog. We will be following up
    with lots of documentation and communication in early 2021 with more
    information.

    add `sriov_support` if you need that feature, and to ensure `ena_support`
    is what you intended to be in your template. [GH-5284]

    script causes the connection to be reset, you should set this to `true` to
    prevent errors. [GH-5283]

### BUG FIXES:

* builder/amazon: `force_deregister` works in all regions, not just original
    region. [GH-5250]

    before considering itself connected. [GH-5300]

### BACKWARDS INCOMPATIBILITIES:

* Packer now ships as a single binary, including plugins. If you install packer
    0.9.0 over a previous packer installation, **you must delete all of the
    packer-* plugin files** or packer will load out-of-date plugins from disk.
* Release binaries are now provided via <https://releases.hashicorp.com>.
* Packer 0.9.0 is now built with Go 1.6.
* core: Plugins that implement the Communicator interface must now implement
    a DownloadDir method. [GH-2618]
* builder/amazon: Inline `user_data` for EC2 is now base64 encoded
    automatically. [GH-2539]

    commands on the host after a build has completed for custom packaging or
    publishing of your artifacts. [GH-2706]

    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]

    provisioner to download a file from a container. [GH-2585]

    starts, unless the `discard` option is specified. This prevent failures
    after the build completes. [GH-2626]

    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]

    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.
