CHANGELOG.md

## 1.11.0 (Upcoming)

### NOTES:
* **Breaking Change**: Support for loading single-component plugins has been removed from Packer. [GH-12785](https://github.com/hashicorp/packer/pull/12785)

* **Breaking Change**: Support for loading plugin binaries following
     the naming convention of packer-plugin-name has been dropped. Packer will now only load
     plugins stored under PACKER_PLUGIN_PATH using the expected namespaced
     directory and CHECKSUM files. This change drops support for loading plugin
     binaries in Packer's executable directory or a template's current working
     directory. [GH-12828](https://github.com/hashicorp/packer/pull/12828)

```shell
/Users/dev/.packer.d/plugins
└── github.com
    └── hashicorp
        └── happycloud
            ├── packer-plugin-happycloud_v0.0.1_x5.0_darwin_arm64
            └── packer-plugin-happycloud_v0.0.1_x5.0_darwin_arm64_SHA256SUM
```

### IMPROVEMENTS:
* core: Move to predictable plugin loading schema -  Packer will now only load
     plugins stored under PACKER_PLUGIN_PATH using the expected namespaced
     directory and CHECKSUM files.
     [GH-12828](https://github.com/hashicorp/packer/pull/12828)
* core: Remove support loading single-component plugins.
     [GH-12785](https://github.com/hashicorp/packer/pull/12785)
* core: Packer now considers development binaries when evaluating plugin
     version constraints. This work allows users to use binaries with versions
     reported as "x.y.z-dev" to be used with the Packer `required_plugins`
     block. [GH-12828](https://github.com/hashicorp/packer/pull/12828)

Given the specified version constraint only versions greater than or equal to 1.1.0 will be considered.

```hcl
amazon = {
  source = "github.com/hashicorp/amazon"
  version = ">= 1.1.0"
}
```
If a development binary is installed, Packer will use it if:

1. It is the highest compatible version installed.
2. There is no final plugin version with the same version number installed alongside it.

```shell
/Users/dev/.packer.d/plugins
└─ github.com
   └─ hashicorp
    	└── amazon
          ├── packer-plugin-amazon_v1.1.0_x5.0_darwin_arm64
          ├── packer-plugin-amazon_v1.1.0_x5.0_darwin_arm64_SHA256SUM
          ├── packer-plugin-amazon_v1.1.1-dev_x5.0_darwin_arm64
          └── packer-plugin-amazon_v1.1.1-dev_x5.0_darwin_arm64_SHA256SUM
```

Version 1.1.1-dev of the Amazon plugin will match the specified version constraint and be used for executing the Packer build.

If, however, a 1.1.1 release version of the plugin is available, it will have precedence over the development binary.

```shell
/Users/dev/.packer.d/plugins
└─ github.com
   └─ hashicorp
    	└── amazon
          ├── packer-plugin-amazon_v1.1.1-dev_x5.0_darwin_arm64
          ├── packer-plugin-amazon_v1.1.1-dev_x5.0_darwin_arm64_SHA256SUM
          ├── packer-plugin-amazon_v1.1.1_x5.0_darwin_arm64
          └── packer-plugin-amazon_v1.1.1_x5.0_darwin_arm64_SHA256SUM
```

## 1.10.3 (Upcoming)

### IMPROVEMENTS:
* cmd/fmt: Display actual parsing errors when the `packer fmt` fails to read a
     template containing invalid HCL2 syntax.
     [GH-12870](https://github.com/hashicorp/packer/pull/12870)

## 1.10.2 (March 6, 2024)

### NOTES:
* Continuing the work in in Packer v1.10.0 we introduced the ability to install
     a locally sourced plugin using packer `plugins install --path`, this
     release extends support to development plugin binaries - binaries that
     report "dev" as part of their plugin version. Instead of manually placing a
     downloaded binary into the executable or current working directory we
     encourage you to run the command `packer plugins install –path <path-to-
     downloaded-extracted-binary> github.com/hashicorp/happycloud` to install
     the binary into a Packer compatible path.
     [GH-12855](https://github.com/hashicorp/packer/pull/12855)

### IMPROVEMENTS:
* cmd/plugins: Add support for installing local development binaries to `packer plugins install`.
     [GH-12855](https://github.com/hashicorp/packer/pull/12855)
* core: Validate bucket name when using `hcp_packer_registry` block.
     [GH-12820](https://github.com/hashicorp/packer/pull/12820)
* core: Update github.com/hashicorp/hcp-sdk-go from 0.83.0 to 0.85.0.
     [GH-12850](https://github.com/hashicorp/packer/pull/12850)
     [GH-12827](https://github.com/hashicorp/packer/pull/12827)
 
### BUG FIXES:
* core/hcp: HCP Packer build failures properly distinguish between incompatible
     plugins and general publishing errors.
     [GH-12854](https://github.com/hashicorp/packer/pull/12854)
     [GH-12835](https://github.com/hashicorp/packer/pull/12835)

## 1.10.1 (January 30, 2024)

### NOTES:
* **HCP Packer** has been updated to follow an artifact-agnostic approach for 
     publishing and consuming built artifacts. To best support the new approach, HCP Packer components within Packer have
     been updated to use the v2 nomenclature when publishing build metadata to
     HCP Packer. These changes include data source components for consuming HCP
     Packer stored artifacts. The data source components [hcp-packer-version](https://developer.hashicorp.com/packer/docs/datasources/hcp/hcp-packer-version) 
     and [hcp-packer-artifact](https://developer.hashicorp.com/packer/docs/datasources/hcp/hcp-packer-artifact) respectively replace, the now deprecated, 
     [hcp-packer-iteration](https://developer.hashicorp.com/packer/docs/datasources/hcp/hcp-packer-iteration) 
     and [hcp-packer-image](https://developer.hashicorp.com/packer/docs/datasources/hcp/hcp-packer-image)
     component data sources. The added changes are compatible with all existing HCP Packer workflows and do not warrant any
     immediate template changes by the user. However, we encourage all HCP Packer users to visit the updated 
     HCP Packer [CHANGELOG](https://developer.hashicorp.com/hcp/docs/changelog) to familiarize themselves with the nomenclature changes. 
     [GH-12794](https://github.com/hashicorp/packer/pull/12794) [GH-12799](https://github.com/hashicorp/packer/pull/12799)
* The `hcp-packer-image` data source has been deprecated, please use HCP Packer
     Artifact data source instead.
     [GH-12794](https://github.com/hashicorp/packer/pull/12794)
* The `hcp-packer-iteration` data source has been deprecated, please use HCP
     Packer Version data source instead.
     [GH-12794](https://github.com/hashicorp/packer/pull/12794)
* The contextual variable `packer.iterationID` has been deprecated, please use
     the new contextual variable `packer.versionFingerprint`. The iterationID
     represents the HCP Packer iteration that build metadata has been publish
     to, with this release an Iteration is now referred to as a Version and the
     ID has been replaced by the Version Fingerprint.
     [GH-12803](https://github.com/hashicorp/packer/pull/12803)

### FEATURES:
* **New Data source** `hcp-packer-artifact` The HCP Packer Artifact Data Source
     retrieves information about an artifact from the HCP Packer Registry.
     [GH-12794](https://github.com/hashicorp/packer/pull/12794)
* **New Data source** `hcp-packer-version`  The HCP Packer Version Data Source
     retrieves information about HCP Packer Version from the HCP Packer.
     Registry. [GH-12794](https://github.com/hashicorp/packer/pull/12794)

### SECURITY:
* core: Bump Go dependencies to address various CVEs. [GH-12777](https://github.com/hashicorp/packer/pull/12777)
* core: Bump github.com/cloudflare/circl to address GHSA-9763-4f94-gfch. [GH-12781](https://github.com/hashicorp/packer/pull/12781)

### IMPROVEMENTS:
* core: Bump github.com/hashicorp/hcp-sdk-go from 0.79.0 to 0.81.0
     [GH-12792](https://github.com/hashicorp/packer/pull/12792)
     [GH-12764](https://github.com/hashicorp/packer/pull/12764)
* core: Update error messaging for HCP incompatible plugin builds.
     [GH-12800](https://github.com/hashicorp/packer/pull/12800)
* core: Update HCP Packer integration to use HCP Packer v2 nomenclature, with
     this change HCP Packer iterations are now referred to as Versions, and
     Images are now referred to as Artifacts. The data sources for interacting
     with HCP Packer have been respectively renamed to align with the terminology
     of Version and Artifact.
     [GH-12794](https://github.com/hashicorp/packer/pull/12794)
     [GH-12799](https://github.com/hashicorp/packer/pull/12799)
* core: Update spacing for flags within Help text.

     [GH-12743](https://github.com/hashicorp/packer/pull/12743)


## 1.10.0 (December 5, 2023)

### NOTES:
This release contains breaking changes for practitioner relying on plugins
     previously bundled into Packer. As specified in the [Bundled Plugins Removal announcement](https://www.hashicorp.com/blog/announcing-the-removal-of-bundled-plugins-in-hashicorp-packer)
     HashiCorp maintained plugins will no longer be shipped with Packer. 
     Users are encouraged to use `packer init` or `packer plugins [...]` when managing required plugins
     needed for executing their builds.
     [GH-12660](https://github.com/hashicorp/packer/pull/12660)

The affected plugins include:
* [packer-plugin-amazon](https://github.com/hashicorp/packer-plugin-amazon) 
* [packer-plugin-ansible](https://github.com/hashicorp/packer-plugin-ansible) 
* [packer-plugin-azure](https://github.com/hashicorp/packer-plugin-azure) 
* [packer-plugin-docker](https://github.com/hashicorp/packer-plugin-docker) 
* [packer-plugin-googlecompute](https://github.com/hashicorp/packer-plugin-googlecompute) 
* [packer-plugin-qemu](https://github.com/hashicorp/packer-plugin-qemu)

* [packer-plugin-vsphere](https://github.com/hashicorp/packer-plugin-vsphere) 

### SECURITY:
* Bump github.com/go-jose/go-jose/v3 to address GO-2023-2334. There have been
     no reported issues with Packer but we are bumping given that it is a
     secondary
     dependency. [GH-12723](https://github.com/hashicorp/packer/pull/12723)
* Bump Go to 1.20.10 to Address CVE-2023-44487 / CVE-2023-39325.
     [GH-12661](https://github.com/hashicorp/packer/pull/12661)
* Bump Go to 1.20.11  CVE-2023-45283. There have been no reported issues with
     Packer but we are bumping given its usage of the path/filepath pkg.
     [GH-12690](https://github.com/hashicorp/packer/pull/12690)
* Bump Packer Plugin SDK to v0.5.2.
     [GH-12717](https://github.com/hashicorp/packer/pull/12717)

### PLUGINS:

* Removed all HashiCorp vendored plugins from being bundled into the Packer binary.
[GH-12660](https://github.com/hashicorp/packer/pull/12660), [GH-12720](https://github.com/hashicorp/packer/pull/12720)
* packer-plugin-hcloud: The Hetzner Cloud plugin has been handed over to the
 Hetzner integrations team. New releases for this plugin are available at
     https://github.com/hetznercloud/packer-plugin-hcloud. Existing references
     to the plugin will continue to work but users are advised to update the
     `required_plugins` block to use the new plugin source address.
    ```
    required_plugins {
       parallels = {
         source  =  "github.com/hetznercloud/hcloud"
         version =  "~> 1"
       }
    }
    ```
### IMPROVEMENTS:
* cmd/init: Warn users running `packer init` on configuration templates with a
     missing `required_plugins` blocks.
     [GH-12638](https://github.com/hashicorp/packer/pull/12638)
* cmd/plugins: Add `--path` flag to `packer plugins install` subcommand to
     support installation of plugins from a local binary rather than from
     GitHub. [GH-12643](https://github.com/hashicorp/packer/pull/12643)
* cmd/plugins: Install SHA256SUM file with 0644 perms.
     [GH-12665](https://github.com/hashicorp/packer/pull/12665)
* cmd/plugins: Remove SHA256SUM file on plugin removal.
     [GH-12666](https://github.com/hashicorp/packer/pull/12666)
* cmd/plugins: Remove will error if it fails to find the plugin being selected
     for removal. [GH-12669](https://github.com/hashicorp/packer/pull/12669)
* core/hcl2: Remove empty source file reference on unset variable errors.
     [GH-12712](https://github.com/hashicorp/packer/pull/12712)
* core/hcl: Improve the recursive execution of data sources with other data
     source dependencies.
     [GH-12608](https://github.com/hashicorp/packer/pull/12608)
* core: Bump github.com/hashicorp/hcp-sdk-go from 0.73.0 to 0.74.0 -
     [GH-12704](https://github.com/hashicorp/packer/pull/12704)
* core: Bump Packer Plugin SDK to v0.5.2.
     [GH-12717](https://github.com/hashicorp/packer/pull/12717)
* core: Provide integration link as hint in error message if a plugin component
     is unknown. [GH-12705](https://github.com/hashicorp/packer/pull/12705)
* core: Update version output for `packer -v` and `packer --version` to match
     `packer version`.
     [GH-12569](https://github.com/hashicorp/packer/pull/12569)
* docs: Update plugin installation guides with supported methods for 1.10.0 and
     above. [GH-12713](https://github.com/hashicorp/packer/pull/12713)

### BUG FIXES:

* cmd/plugins: Update `packer plugin installed` to show all installed plugin
     binaries, including any duplicate versions or binaries copied from a
     different source URI.
     [GH-12731](https://github.com/hashicorp/packer/pull/12731)

## 1.9.5 (December 4, 2023)

### SECURITY

* Bump github.com/go-jose/go-jose/v3 to address GO-2023-2334.
     [GH-12723](https://github.com/hashicorp/packer/pull/12723)

### BUG FIXES:

* Add VirtualBox as known plugin prefix to prevent endless bundled plugin warning.
     [GH-12719](https://github.com/hashicorp/packer/pull/12719)

## 1.9.4 (August 18, 2023)

### BUG FIXES:

* core: When invoking Packer with the CHECKPOINT_DISABLE environment variable the telemetry
    reporter is left uninitialized in order to disable telemetry reporting.
    Any method calls on the nil reporter is expected to check if the reporter is active or in
    NOOP mode. The SetBundledUsage function, introduced in Packer 1.9.2, failed to perform a nil
    check before attempting to modify an attribute, causing Packer to fail when telemetry is
    disabled. This release fixes this issue by introducing such a check.

## 1.9.3 (August 17, 2023)

### NOTES:
* **New Docker Image**: As part of the bundled plugin removal effort, a new
     Docker target called `release-full` has been added to the Packer release
     artifacts. The release-full image includes Packer and all the official
     plugins pre-installed in its environment. This image is being offered as an
     alternative option for those users who may still be relying on the plugin
     versions bundled into the Packer binary.
     [GH-12532](https://github.com/hashicorp/packer/pull/12532)

### IMPROVEMENTS:
* core/docs: Clarify the expected usage of the `packer init` command for HCL2
     template builds.[GH-12535](https://github.com/hashicorp/packer/pull/12535)
* core/hcp: Add support for project-level service principals. A user connecting
     with a project level service principals must provide a valid HCP_PROJECT_ID
     in order to connect.
     [GH-12520](https://github.com/hashicorp/packer/pull/12520)
     [GH-12576](https://github.com/hashicorp/packer/pull/12576)
* core: A new Docker image `packer:release-full` has been added for all
     supported architectures. The release-full image includes Packer and all the
     official plugins pre-installed in its environment.
     [GH-12532](https://github.com/hashicorp/packer/pull/12532)
* core: Add enhanced support to Packer telemetry for bundle plugins usage.
     [GH-12536](https://github.com/hashicorp/packer/pull/12536)

### BUG FIXES:

* core: Bump golang.org/x/net to v0.13.0 to address CVE GO-2023-1988. Packer
     itself is not vulnerable to the CVE as we don't render web pages, but
     security checks do point it as an issue that needs to be addressed.
     [GH-12561](https://github.com/hashicorp/packer/pull/12561)
* core: Fix custom plugin loading in current working directory regression.
     [GH-12544](https://github.com/hashicorp/packer/pull/12544)


## 1.9.2 (July 19, 2023)

### NOTES:

* Vendored plugins within Packer have not been updated. Plugin releases occur on
     a regular basis to address issues and feature requests.
     Please note that in an upcoming version of Packer, we will remove the last
     bundled plugins from Packer. Users are encouraged to use `packer init` for HCL2 templates or
     `packer plugins install` with legacy JSON templates for installing external
     plugins.

* Packer will now warn when using bundled plugins. This feature will be removed in
    a future version of the tool, so this warning is meant to bring awareness of the
    upcoming change, and help users update their templates.
    [GH-12495](https://github.com/hashicorp/packer/pull/12495)

### BUG FIXES:

* Fixed a bug with how Packer was discovering plugins: in order to load
     plugins, Packer would recursively scan all the known directories in which
     we could have installed plugins. This caused unnecessary directory
     walks and slowdowns upon invocation. Packer will now only check
     for nested plugins within the directories used by commands such as `packer
     init`, or `packer plugins install`, or as defined in PACKER_PLUGIN_PATH.
     Refer to
     [Packer's plugin directory documentation](https://developer.hashicorp.com/packer/docs/configure#packer-s-plugin-directory)
     for details on how loading works.
     [GH-12414](https://github.com/hashicorp/packer/pull/12414)

* The `packer init` subcommand now bundles all the missing installed plugins into one
    condensed warning, as opposed to one warning per missing plugin.
    [GH-12506](https://github.com/hashicorp/packer/pull/12506)

### PLUGINS:

* packer-plugin-parallels: The Parallels plugin has been handed over to the Parallels
     team. New releases for this plugin are available at
     https://github.com/parallels/packer-plugin-parallels. This plugin is no longer
     being bundled in the Packer binary release. Existing references to the
     plugin will continue to work but users are advised to update the
     `required_plugins` block to use the new plugin source address.
    [GH-12476](https://github.com/hashicorp/packer/pull/12476)
    ```
     required_plugins {
       parallels = {
         source  =  "github.com/parallels/parallels"
         version =  "~> 1"
        }
    }
    ```

### IMPROVEMENTS:

* The `hcl2_upgrade` sub-command will now add `required_plugins` to the template
    generated from JSON for [official plugins](https://developer.hashicorp.com/packer/plugins#tiers-and-namespaces).
    [GH-12504](https://github.com/hashicorp/packer/pull/12504)

## 1.9.1 (June 1, 2023)

### BUG FIXES:

* On May 16th 2023, HCP introduced multi-project support to the platform.
    In order to use multiple projects in your organization, you will need to update Packer
    to version 1.9.1 or above. Starting with 1.9.1, you may specify a project ID to push
    builds to with the `HCP_PROJECT_ID` environment variable. If no project ID is specified,
    Packer will pick the project with the oldest creation date. Older versions of Packer are
    incompatible with multi-project support on HCP, and builds will fail for HCP
    organizations with multiple projects on versions before 1.9.1.
    [GH-12453](https://github.com/hashicorp/packer/pull/12453)

## 1.9.0 (May 31, 2023)

### NOTES:

* **Breaking Change**: Iteration fingerprints used to be computed from the Git SHA of the
     repository where the template is located when running packer build. This
     changes with this release, and now fingerprints are automatically generated
     as a ULID. This implies that continuing an existing iteration will require
     users to define the fingerprint in the environment manually in order to
     adopt this behaviour, otherwise, by default, a new iteration will be
     created. This does not impact workflows where the fingerprint was defined
     through the `HCP_PACKER_ITERATION_FINGERPRINT` environment variable, and
     these builds will work exactly as they did before.
     [GH-12172](https://github.com/hashicorp/packer/pull/12172)

* **Breaking Change**: Community-maintained plugins bundled with the Packer binary have been removed.
     These external plugin components are released independently of Packer core and can be installed
     directly by the user. Users relying on the external plugin components listed below should refer
     to the `packer plugins` sub-command and, if using HCL2, a `required_plugins` block to define a
     list of plugins for building a template.

### PLUGINS

* Remove provisioner plugins for Chef, Converge, Puppet, Salt, and Inspec as
     vendored plugins. These plugins have been previously archived and not
     updated in release since being archived. These plugins can be installed
     using `packer init` or with the Packer plugins sub-command `packer plugins install github.com/hashicorp/chef`.
     [GH-12374](https://github.com/hashicorp/packer/pull/12374)

* The following community plugins won't be bundled with Packer anymore:

    [GH-12436](https://github.com/hashicorp/packer/pull/12436)

Users relying on these external plugin components should refer to the `packer plugins` sub-command and,
if using HCL2, a `required_plugins` block to define a list of plugins to use for building a template.

### IMPROVEMENTS:

* core/hcp: Now, fingerprints used by HCP Packer are randomly generated ULIDs
     instead of a Git SHA, and a new one is always generated, unless one is
     specified in the environment.
     [GH-12172](https://github.com/hashicorp/packer/pull/12172)

### BUG FIXES:

* Fix LDFLAGS for release pipelines: Between Packer 1.8.5 and Packer 1.8.7, changes
    to the LDFLAGS in use for building the binaries for Packer had mistakenly
    removed some compilation flags, leading to the final binaries not being stripped.
    This change raised the size of the built binaries by as much as 45%.
    In this release, we fixed the LDFLAGS during compilation, yielding leaner binaries.

* Bumped gopsutil to v3. This fixes a macOS intermittent crash reported by the community
    [GH-12430](https://github.com/hashicorp/packer/issues/12430)

### HCP Packer -- Multi project support advisory

If using HCP Packer to store metadata on your builds, please be aware that Packer
does not support this feature yet, and as such, having multiple projects in your
organization will make it impossible to use HCP Packer in this release.

We are actively working on supporting this feature, which will be available in a
subsequent release.

## 1.8.7 (May 4, 2023)

### NOTES:
* Vendored plugins within Packer have not been updated. Plugin releases occur on
     a regular basis to address issues and feature requests. Users are encouraged
     to use `packer init` for HCL2 templates or `packer plugins install` with
     legacy JSON templates for installing external plugins. 

* packer-plugin-digitalocean: The Digital Ocean Packer plugin has been handed
     over to the Digital Ocean team. New releases for this plugin are available
     at https://github.com/digitalocean/packer-plugin-digitalocean.

        }
    }
    ```
* packer-plugin-profitbricks: The Profitbricks plugin has been removed as a
     bundled plugin in Packer. New releases for this plugin are available at
     https://github.com/hashicorp/packer-plugin-profitbricks. This plugin is is
     no longer being bundled in the Packer binary release. Existing references

### BUG FIXES
* cmd/hcl2_upgrade: Fix a crash when running the hcl2_upgrade command against a
     legacy JSON template containing user variables with an undefined variables
     block. [GH-12257](https://github.com/hashicorp/packer/pull/12257)

     variables. [GH-12290](https://github.com/hashicorp/packer/pull/12290)


## 1.8.6 (February 15, 2023)

### NOTES:
* core: Users will see some changes in how names are displayed during a Packer
     build for JSON templates. Previously only the builder type or the builder
     name, if it was set, would be displayed. Now for named builders
     (`"name":"mybuilder"`) the builder's type and name will be displayed (i.e
     "<type>.mybuilder". This does not impact the behavior of options such as
     only or except, they will continue to work as they did before.)

### PLUGINS:

     [GH-12250](https://github.com/hashicorp/packer/pull/12250)
* core/hcl2: Templates with build blocks referencing an unknown source block
     would display an empty string for the template filename at line 0, which
     made it difficult to identify the broken build block. Packer has been
     updated to display the proper filename and line number where the unknown
     reference resides.

     [GH-12235](https://github.com/hashicorp/packer/pull/12235)

## 1.8.5 (December 12, 2022)

### NOTES:
* data/packer-image-iteration has been removed. This was an undocumented and
     unusable data source that was built for experimentation but not released. It
     should not affect users in any way but is being mentioned for visibility
     purposes.
     [GH-12111](https://github.com/hashicorp/packer/pull/12111)

### FEATURES:
* core: Metadata for capturing template types such as JSON or HCL2 has been added to the
     HCP Packer registry metadata. Upon running a `packer build` the type of
     template used during execution will be sent along to the registry as
     additional build metadata.[GH-12132](https://github.com/hashicorp/packer/pull/12132)

### PLUGINS:

     variables. [GH-12136](https://github.com/hashicorp/packer/pull/12136)
* cmd/validate: Add support for the `-evaluate-datasources` flag to evaluate
     the data sources from a template during validation time.
     [GH-12106](https://github.com/hashicorp/packer/pull/12106)
     [GH-12152](https://github.com/hashicorp/packer/pull/12152)
* core/hcl2: Variable definition files containing undeclared variables within
     an HCL2 template will no longer warn during build execution. Warnings will
     be displayed to a user during template validation, which can be disabled by
     passing the `-no-warn-undeclared-var` flag to the validate command.
     [GH-12104](https://github.com/hashicorp/packer/pull/12104)
     [GH-12109](https://github.com/hashicorp/packer/pull/12109)

* core: Split HCP Packer publishing components into a separate internal-only
     module. [GH-11](https://github.com/hashicorp/packer/pull/11967)
     [GH-12116](https://github.com/hashicorp/packer/pull/12116)

### BUG FIXES:
* cmd/init: The init command will try to fallback to the next available version
     for a plugin, if the most recent version is not available or has a missing
     checksum file. This should prevent Packer from trying to install versions
     that have a GitHub tag but no actual assets.
     [GH-12103](https://github.com/hashicorp/packer/pull/12103)
* cmd/plugins: The `plugins install` sub-command will try to fallback to the
     next available version for a plugin, if the most recent version is not
     available or has a missing checksum file. This should prevent Packer from
     trying to install versions that have a GitHub tag but no actual assets.
     [GH-12103](https://github.com/hashicorp/packer/pull/12103)
* core: Bump Go version to 1.18.9 to address vulnerability GO-2022-1144, which
     concerns the net/http and golang.org/x/net
     packages.[GH-12153](https://github.com/hashicorp/packer/pull/12153)
     [GH-12158](https://github.com/hashicorp/packer/pull/12158)
* core: Fix the registration of deleted input artifacts in HCP Packer when
     setting `keep_input_artifacts` to
     false.[GH-11462](https://github.com/hashicorp/packer/pull/11967)
* core: Using different template types when building a HCP Packer
     image iteration will now trigger a runtime build error due to the 
     mixing of template types.
     [GH-12132](https://github.com/hashicorp/packer/pull/12132)

## 1.8.4 (October 28 2022)

### NOTES:

* Packer user documentation has been moved to the new HashiCorp developer
     documentation portal. The main Packer site (https://www.packer.io) will
     continue to be the home for Packer but all requests for general
     documentation and binary downloads will be redirected to
     https://developer.hashicorp.com/packer. Users are encouraged to visit the
     developer documentation portal for access to all Packer related
     documentation; including integrations with HCP Packer.

* The Oracle builder and post-processor are no longer vendored with Packer
     core. Users of the Oracle plugin should use `packer init` to install the
     latest version of the plugin. See the [Oracle Plugin
     Documentation](https://github.com/hashicorp/packer-plugin-oracle) for more
     information. [GH-11983](https://github.com/hashicorp/packer/pull/11983)

* HCP Packer environment variables: The behavior of some HCP Packer-specific
     environment variables have changed slightly. Refer to [HCP Packer](https://developer.hashicorp.com/packer/docs/hcp)
     in the Packer documentation for a full list of HCP Packer environment variables. [GH-12059](https://github.com/hashicorp/packer/pull/12059)
    - For JSON templates, the `HCP_PACKER_REGISTRY` environment variable was
     previously required to enable the HCP Packer integration. In this release,
     the environment variable is now optional, and can be used for disabling the
     publishing of metadata for any HCP Packer enabled configuration template.
    - For HCL2 templates, the `HCP_PACKER_REGISTRY` environment variable can be used
     to disable publishing to a HCP Packer registry even if the template defines a
     `hcp_packer_registry` block. This can be useful for testing that a template
     works as intended prior to pushing metadata to HCP Packer.
    - The `HCP_PACKER_BUCKET_NAME` environment variable is now the only
     requirement to push metadata to a HCP Packer registry, in both JSON 
     and HCL2 templates without a `hcp_packer_registry` block.

### FEATURES:

* provisioner/powershell: Add `use_pwsh` configuration argument to support pwsh
     in powershell provisioner. [GH-11950](https://github.com/hashicorp/packer/pull/11950)

### PLUGINS:

* builder/oracle: Remove Oracle plugin from the list of vendored
     plugins. [GH-11983](https://github.com/hashicorp/packer/pull/11983)

### IMPROVEMENTS:

* command/hcl2_upgrade: Has been updated to persist all possible template
     engine options that were supported by the legacy JSON templates. While the
     upgrade command copies the template engine options as is support for the
     template options may not actually work with HCL2 templates; indicated by an
     error similar to `fieldname type <no value> is invalid`. Before executing a
     build with the upgraded template you are encouraged to run `packer validate`
     against the template and fix any invalid `<no value>` references.
     [GH-12068](https://github.com/hashicorp/packer/pull/12068)
* core/hcl2: Packer will now report an error when executing a build with no
     sources selected for execution.
     [GH-12016](https://github.com/hashicorp/packer/pull/12016)
* core/hcp: Configuration errors for HCP Packer enabled builds have been
     consolidated into a single report to help users address all potential
     issues before retrying their build.
     [GH-12031](https://github.com/hashicorp/packer/pull/12031)
* core/hcp: Named builds within a legacy JSON template are now published to a
     HCP Packer registry using its full build name (e.g `happycloud.windows-srv-2019)`, 
     as opposed to just the build name field (e.g `"name"="windows-srv-2019"`). 
     Builders with no defined name will continue to publish build
     metadate using the builder type as the build name (e.g `happycloud`).
     [GH-12059](https://github.com/hashicorp/packer/pull/12059)
* core:hcl2: When a variable is set in a variables definitions file (i.e
     \*.pkrvars.hcl), but isn't defined with the template files (i.e
     \*.pkr.hcl), the outputted error message will now include an example of
     variable block that can be added to the build template to remedy the issue.
     [GH-12020](https://github.com/hashicorp/packer/pull/12020)
* core: Add ppc64le to binary releases for Linux.
     [GH-11966](https://github.com/hashicorp/packer/pull/11966)
* core: Bump github.com/hashicorp/packer-plugin-sdk from 0.3.1 to 0.3.2.
     [GH-11981](https://github.com/hashicorp/packer/pull/11981)

     [GH-11927](https://github.com/hashicorp/packer/pull/11927)

### BUG FIXES:

     [GH-12009](https://github.com/hashicorp/packer/pull/12009)

## 1.8.3 (August 2, 2022)

### NOTES:
* There's been a change in the way the `ssh_timeout` and the
    `ssh_handshake_attempts` configuration arguments work together. The
    behaviour is unchanged if both or none are specified. However, if only one
    of the two is set the other won't have a default value anymore and will be
    ignored. See [Packer Plugin SDK change](https://github.com/hashicorp/packer-plugin-sdk/pull/116) for details

* packer-plugin-digitalocean: The Digital Ocean Packer plugin has been handed over
    to the Digital Ocean team. New releases for this plugin are available at
    https://github.com/digitalocean/packer-plugin-digitalocean. This plugin is
    still being bundled in the Packer binary but will be removed in a future
    release. Existing references to the plugin will continue to work but
    users are advised to update the required_plugins block to use the new
    plugin source address.

* packer-plugin-scaleway:  The Scaleway Packer plugin managed by the Scaleway
    team, since Packer 1.7.7, has been removed from the Packer binary. Users are
    advised to install the latest version of the plugin by running
    `packer plugins install github.com/scaleway/scaleway`. [GH-11912](https://github.com/hashicorp/packer/pull/11912)

### FEATURES:
* Future Scaffolding: This release contains additional changes that allow
    Packer core to validate that a newly built image is a direct child of a HCP
    Packer registry source image. This feature is only available for HCP Packer
    enabled builds using the `hcp_packer_image` and `hcp_packer_iteration` data
    source for setting a builder's source image.
    [GH-11861](https://github.com/hashicorp/packer/pull/11861)

### PLUGINS:

The following external plugins have been updated and pinned to address open
    issues. Please see their respective changelogs for details on plugin
    specific bug fixes and improvements.

* amazon@v1.1.2 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-amazon/releases/tag/v1.1.2)
* ansible@v1.0.3 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-ansible/releases/tag/v1.0.3)
* azure@v1.3.0 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-azure/releases/tag/v1.3.0)
* docker@v1.0.7 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-docker/releases/tag/v1.0.7)
* googlecompute@v1.0.14 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-googlecompute/releases/tag/v1.0.14)
* lxc@v1.0.2 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-lxc/releases/tag/v1.0.2)
* triton@v1.0.2 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-triton/releases/tag/v1.0.2)
* vsphere@v1.0.7 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-vsphere/releases/tag/v1.0.7)
* yandex@v1.1.2 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-yandex/releases/tag/v1.1.2)


### IMPROVEMENTS:
* Bump packer-plugin-sdk to v0.3.1 to fix inconsistencies between `ssh_timeout`
    and `ssh_handshake_attempts` configuration arguments in the SSH
    communicator. [GH-11909](https://github.com/hashicorp/packer/pull/11909)
* core: During long running builds the HCP Packer registry will mark a build as
    timed out if it has not posted an update after a certain number of minutes.
    For HCP Packer enabled builds a status update will now be sent every 2
    minutes to the registry to prevent long builds from being marked as timed
    out. [GH-11846](https://github.com/hashicorp/packer/pull/11846)
* data/hcp_packer_image: Add `component_type` configuration argument to
    support specifying an exact build image when multiple images exist in the
    same provider and region for a given HCP Packer bucket iteration.
    [GH-11872](https://github.com/hashicorp/packer/pull/11872)
* data/hcp_packer_image: Add support for `channel` as input argument to
    retrieve an image from the associated iteration. If
    using several images from a single iteration, you may prefer sourcing an
    iteration first, and referencing it for subsequent uses, as every
    `hcp_packer_image` with the channel set will generate a potentially
    billable HCP Packer request but if several `hcp_packer_image`s use a
    shared `hcp_packer_iteration` that will only generate one potentially
    billable request.
    [GH-11865](https://github.com/hashicorp/packer/pull/11865)



### BUG FIXES

* core/hcl2: Fix crash when parsing malformed provisioner override blocks.
    [GH-11881](https://github.com/hashicorp/packer/pull/11881)
* core/hcl2: Fix crash when running `packer validate` on templates containing
    one or more  HCP Packer data sources.
    [GH-11883](https://github.com/hashicorp/packer/pull/11883)


## 1.8.2 (June 21, 2022)

### NOTES:
* The Packer plugin SDK includes the latest version of the go-getter library,
    which has been updated to address the vulnerabilities listed in
    [HCSEC-2022-13](https://discuss.hashicorp.com/t/hcsec-2022-13-multiple-vulnerabilities-in-go-getter-library/39930).
    The updated SDK contains changes that can
    be breaking for some plugins as the updated go-getter settings in the SDK
    prevent reading/writing through symlinks and to sub-directories that
    require upward path traversal (e.g /tmp/.../etc/hosts). The updates also
    includes a 30 minute maximum timeout for file downloading, which can be an
    issue for very large or slow downloads if they exceed more than 30 minutes
    to complete.

### SECURITY:
* Bump packer-plugin-sdk to v0.3.0 to address reported vulnerabilities within
    the go-getter library.
    [GH-11843](https://github.com/hashicorp/packer/pull/11843)
* Bump plugins relying on go-getter for downloading remote files to address
    reported vulnerabilities within the go-getter library. See [HCSEC-2022-13](https://discuss.hashicorp.com/t/hcsec-2022-13-multiple-vulnerabilities-in-go-getter-library/39930) for details.
    [GH-11844](https://github.com/hashicorp/packer/pull/11844)

### FEATURES:
* Future Scaffolding: This release contains changes that allow Packer core to
    validate that a newly built image is a direct child of a HCP Packer
    registry source image. This feature is only available for HCP Packer
    enabled builds using the `hcp_packer_image` data source for setting a
    builder's source image.
    [GH-11832](https://github.com/hashicorp/packer/pull/11832)

* vsphere@v1.0.5 - [CHANGELOG](https://github.com/hashicorp/packer-plugin-vsphere/releases/tag/v1.0.5)

### IMPROVEMENTS:
* Add `pause_after` configuration argument to Powershell provisioner.
    [GH-11792](https://github.com/hashicorp/packer/pull/11792)
* HCP Packer data sources will now fail for revoked iterations to prevent building non-compliant images.
    [GH-11854](https://github.com/hashicorp/packer/pull/11854)

### BUG FIXES:

* Add missing support for the `env` configuration argument in remote shell
    provisioners. [GH-11819](https://github.com/hashicorp/packer/pull/11819)
* The preinst and postrm user scripts, including the service configuration
    directives, have been removed from the Packer rpm installations packages,
    as Packer does not require a service user in order to run.
    [GH-11831](https://github.com/hashicorp/packer/pull/11831)

## 1.8.1 (May 27, 2022)

### NOTES:
* All bundled plugins have been updated to their latest release to address any
    open issues pertaining to the legacy SSH key algorithm fix made to the
    Packer plugin SDK.
    [GH-11761](https://github.com/hashicorp/packer/pull/11761)
    [GH-11802](https://github.com/hashicorp/packer/pull/11802)
* This release contains the latest golang.org/x/crypto/ssh module which
    implements client authentication support for signature algorithms based on
    SHA-2 for use with existing RSA keys. Previously, a client would fail to
    authenticate with RSA keys to servers that reject signature algorithms
    based on SHA-1.

### FEATURES:
* **New Datasource** HTTP data source retrieves information from a HTTP
    endpoint to be used during Packer builds.
    [GH-11658](https://github.com/hashicorp/packer/pull/11658)

    [GH-11754](https://github.com/hashicorp/packer/pull/11754)

## 1.8.0 (March 4, 2022)

### NOTES:
* **Breaking Change**: Support for the following  architectures `ppc64le, mips,
     mips64, mipsle, mipsle64, s390x` have been removed from the Packer releases
     page. Packer, along with the HashiCorp maintained Packer plugins, have been
     updated to release binaries for the HashiCorp supported architectures arm,
     arm64, 386, and amd64. A full list of supported platforms can be found
     on the [Packer Downloads](https://www.packer.io/downloads) page.
    [GH-11564](https://github.com/hashicorp/packer/pull/11564)
    [GH-11601](https://github.com/hashicorp/packer/pull/11601)
    [GH-11603](https://github.com/hashicorp/packer/pull/11603)

* **Breaking Change**: The `packer-plugin-check`(github.com/hashicorp/packer/cmd/packer-plugins-check) has been
     replaced by the [`packer-sdc plugin-check` command](https://github.com/hashicorp/packer- plugin sdk/tree/main/cmd/packer-sdc#packer-sdc).
     Plugin maintainers who may be using the packer-plugin-check as part of their
     release pipeline are encouraged to move to the packer-sdc command. As an
     alternative, maintainers can continue to use the packer-plugin-check by
     pinning the command to Packer 1.7.10.
     [GH-11317](https://github.com/hashicorp/packer/pull/11317)

### FEATURES
* **New Command** `packer plugins` command and subcommands to manage external
    plugins. [GH-11553](https://github.com/hashicorp/packer/pull/11553)
    [GH-11625](https://github.com/hashicorp/packer/pull/11625)

### IMPROVEMENTS
* core: Add a `env` argument to provisioner blocks that allow for setting a
    map of key/value pairs to inject prior to the execute_command. The env argument
    is an alternative to using environment_vars for setting environment variables,
    which has the added ability to read from Packer datasources. [GH-11569](https://github.com/hashicorp/packer/pull/11569)
* core: Bump version of go-getter to allow for downloading ISOs with PGP signed
    checksums. [GH-11495](https://github.com/hashicorp/packer/pull/11495)
* core: Docker images are now available for all supported architectures that
    the linux binaries are built for including arm, arm64, 386, and amd64

    [GH-11603](https://github.com/hashicorp/packer/pull/11603)
* core: The dockerfile that is used to build the packer docker image available
    at hashicorp/packer now lives in the root of this repo. The README that
    describes how to build the docker targets defined in the Dockerfile are
    available under ./release/docker/README.md.
    [GH-11564](https://github.com/hashicorp/packer/pull/11564)

    [GH-11603](https://github.com/hashicorp/packer/pull/11603)
* core: The packer-plugin-check command has been removed. Plugin maintainers
    should update their release configuration to use the `packer-sdc plugin-
    check` command.  [GH-11317](https://github.com/hashicorp/packer/pull/11317)


### BUG FIXES
* core/hcl2: Fixes an issue preventing builds from pausing between provisioners when
    the `--debug` argument has been passed.
    [GH-11537](https://github.com/hashicorp/packer/pull/11537)
* core/hcl2: Fixes a data loss issue when merging an empty-object map to a non-
    empty map variable.
    [GH-11566](https://github.com/hashicorp/packer/pull/11566)
* core/hcl2: Fixes a regression where references to locals via the lookup
    function were failing to find defined keys.

* core/hcl2: Fixes an issue where HCP Packer build labels from the first
    completed build image were being copied to all images within the same
    build. [GH-11574](https://github.com/hashicorp/packer/pull/11574)
    [GH-11584](https://github.com/hashicorp/packer/pull/11584)
* core: HCP Packer datasources will no longer fail for iterations with
    scheduled revocations.
    [GH-11619](https://github.com/hashicorp/packer/pull/11619)
* core: Packer darwin builds now use macOS system DNS resolver for resolving
    hostnames. [GH-9710](https://github.com/hashicorp/packer/issues/9710)
    [GH-11564](https://github.com/hashicorp/packer/pull/11564)

## 1.7.10 (February 02, 2022)

* The `hcp_packer_registry.labels` argument has been deprecated in favor of the
    new `bucket_labels` argument to support custom user generated bucket
    labels. [GH-11401](https://github.com/hashicorp/packer/pull/11401)
* The code of the Outscale builder was handed over to the outscale org
    [GH-11428](https://github.com/hashicorp/packer/pull/11428)
* Version information for external plugins has been added as a badge to the
    plugin documentation.
    [GH-11457](https://github.com/hashicorp/packer/pull/11457)

## 1.7.3 (June 15, 2021)

### IMPROVEMENTS:

We've extracted a majority of HashiCorp-maintained and community plugins from the Packer Core repository. They now live in their own multi-component plugin repositories. This is not a breaking change as we are enabling backwards compatibility in this release by vendoring components back into Packer.
However, we encourage users to begin using `packer init` to download and install plugins to get the latest updates to each plugin, and to prepare for Packer v2.0 when we will stop vendoring the above plugins into the main Packer binary.

The following repositories have been created, and their components have been deleted from the "github.com/hashicorp/packer" repository.

    more details. [GH-10240]
* **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.

### 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

    commands on the host after a build has completed for custom packaging or
    publishing of your artifacts. [GH-2706]
* **Artifice post-processor**: Override packer artifacts during post-
    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]
* core: Packer now indicates line numbers for template parse errors. [GH-2742]
* core: Scripts are executed via `/usr/bin/env bash` instead of `/bin/bash`
    for broader compatibility. [GH-2913]
