-     [GH-12163](https://github.com/hashicorp/packer/pull/12163)
-
-### BUG FIXES: 
-* 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-12167](https://github.com/hashicorp/packer/pull/12167)
-* core: Linux packages now have vendor label and set the default label to HashiCorp.
-        This fix is implemented for any future releases, but will not be 
-        updated for historical releases.
