Public preview of Workload identity federation for Azure Pipelines

This post announces the public preview of workload identity federation for Azure service connections, which uses OpenID Connect (OIDC) to simplify authentication between Azure Pipelines and Azure. It eliminates the need to manage expiring secrets and improves security by using a federation subject. The post details how to convert existing service connections or create new ones using this scheme, and lists updated built-in Azure Pipelines tasks that support it. It also provides guidance for custom tasks and extensions, including Terraform integration.
