Pulumi
Pulumi spent the last 90 days expanding automation and observability while shipping runtime and SDK improvements across multiple languages. The Automation API gained org command coverage across Node.js and Python, and the engine introduced the OnError resource hook for custom retry policies across Go, Node.js, and Python SDKs. On observability, the CLI shipped OTLP trace export with gRPC support, OTEL resource attributes reading, and a new --urns flag to display full resource URNs in previews and deployments. Runtime support broadened with Bun added as both a project runtime and plugin runtime, and the SDK now supports Python lock file detection for toolchain selection. The engine also automated snapshot integrity repair while improving provider inheritance and enabling journaling by default, though v3.221.0 introduced a breaking change renaming pulumiVersionRange to requiredPulumiVersion in plugin configuration.
March focused on observability infrastructure and runtime expansion. The CLI gained OpenTelemetry tracing capabilities—writing spans to files or gRPC endpoints with header authentication and resource attribute support—while the engine improved snapshot integrity with automatic repair and diagnostics. Pulumi added Bun as a fully supported runtime alongside Node.js, including debugger integration and policy pack execution, and the state management tool now handles bulk resource deletion in dependency-safe order.
