Summary for 2025-09: Implemented two key features in the duplocloud/actions repo that deliver business value and improve pipeline flexibility. 1) Azure Build-Image workflow (ACR): added build-image support to build and push Docker images to Azure Container Registry (ACR), enabling streamlined container deployment and faster delivery to Azure. 2) Terraform-exec action: added a new target input to allow users to specify a specific Terraform resource; the action now conditionally includes the -target flag in apply/plan when provided for more granular control. Also updated the changelog to reflect these capabilities. Commits included: 72176a8eb8777f8c925daf3e35c3a9628ac755b3 (updated changelog) and 52334ddd71a5725a5afce1bec36cc528e360bdc8 (target input added to terraform-exec).
