In the latest release, Pulumi introduced several new features and improvements to enhance user experience and functionality. The updates include enhancements to the Pulumi import feature, which now allows importing infrastructure with all input fields and treats check failures as warnings, along with an optional flag to skip code generation. A new resource option, RetainOnDelete, enables resources to remain in the cloud provider even after deletion from the Pulumi stack. The release also introduces the pulumi state rename command for easier resource renaming and sets the default plugin installation to the latest version, saving users time. Additionally, Pulumi now features a dot spinner in non-interactive mode to prevent CI tools from terminating jobs due to inactivity, and supports the pulumi cancel command for self-managed state backends like S3.
