+## 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.

+* 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

+     [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+     ID has been replaced by the Version Fingerprint.
