Pulumi has introduced various improvements across its engineering areas in January and February, focusing on enhancing user experience and functionality. Key updates include colorized stack traces for Node.js errors in the CLI, the introduction of a --shell option for stack outputs, and support for plugins hosted on GitLab. The Language SDKs saw enhancements such as helper functions for JSON serialization and deserialization, and the Python SDK now supports native arm64 binaries. In the Automation API, users can now programmatically manage stack tags and clone from Azure DevOps. Pulumi has also strengthened its cloud provider offerings with new resources for Azure and AWS, and added community packages to its Registry. Pulumi Deployments now integrate with OpenID Connect (OIDC) to provide temporary credentials and granular access control, improving security and compliance. These updates aim to streamline workflows, improve performance, and enhance security for Pulumi users.
