In early 2020, significant advancements were made in the Pulumi platform, with major updates to the .NET and Go SDKs, the introduction of the Policy as Code framework CrossGuard, and various additional features aimed at improving user experience and functionality. The .NET SDK received enhancements for better alignment with .NET developers, including new examples and closing gaps in core Pulumi features, while the Go SDK underwent a comprehensive overhaul to incorporate strong typing across all resource APIs, moving away from map-based data structures. CrossGuard, designed for writing and enforcing policies in real code, became ready for testing, offering capabilities like policy packs and server-side enforcement for enterprise users. Additional improvements included stack export features, audit logs, runtime mocking for infrastructure testing, and expanded provider support, along with ongoing efforts to improve API documentation, multi-language library architecture, and performance enhancements for a more efficient CLI experience. Pulumi encouraged user feedback and engagement through community platforms to refine these developments further.
