 ### NOTES:
-* **Breaking Change**: The `packer-plugin-check`(github.com/hashicorp/packer/cmd/packer-plugins-check) has been replaced by the [`packer-sdc plugin-check` command](https://github.com/hashicorp/packer-plugin-sdk/tree/main/cmd/packer-sdc#packer-sdc). The previous command was removed to prevent plugin release issues caused by Packer dependencies not related to the actual Packer plugin SDK or the command itself.  [GH-11317](https://github.com/hashicorp/packer/pull/11317)
+* **Breaking Change**: The `packer-plugin-check`(github.com/hashicorp/packer/cmd/packer-plugins-check) has been replaced by the [`packer-sdc plugin-check` command](https://github.com/hashicorp/packer-plugin-sdk/tree/main/cmd/packer-sdc#packer-sdc).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)

 ### IMPROVEMENTS
-* core: Add the `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 has support for reading from datasources, were `environment_vars`
-    does not. [GH-11569](https://github.com/hashicorp/packer/pull/11569)
