October 2025 delivered a foundational and safer workspace import workflow for rudder-iac, with a new importer interface that captures workspace data for planning, complemented by robust safety checks to prevent imports when changes aren’t synced and to avoid overwriting existing import data. We enhanced user experience and interoperability by adding a spinner and data formatter for the import flow, and by separating importable resources in the diff output. The import surface expanded to support upstream custom types, categories, and tracking plans, with tests for data catalog imports and global validation metadata, enabling easier data integration and governance. Stability improvements across planning and state management were achieved through E2E test relocation to generic apply/destroy, tracking plan fixes, deterministic test ordering, stateless CLI state loading, and safer config handling when attaching to state.
