May 2026 monthly summary for cognite-sdk-python. Focused on clarifying the simulation run load balancing behavior in the SDK documentation to improve developer understanding and reduce integration ambiguity. The update clarifies status transitions for simulation runs (queued vs ready) based on integration assignment, supported by the related commit in the repository.

December 2025: Delivered a Python SDK usability improvement by making simulator_integration_external_id optional across SimulatorRoutine, SimulatorRoutineRevision, and SimulationRun, reducing setup friction for users (commit a18702b10e940bec9684589c86bd375a23613258). In the Cognite JS SDK, implemented test coverage reporting via codecov integration and stabilized flaky tests, including dependency updates to latest versions and fixes to a failing test (commit e0cae82e2665aa1b87363ceefd6007e752aa26d3). Overall this month improved developer experience, increased test reliability, and provided measurable coverage signals to guide quality improvements.

Monthly summary for 2025-11 focusing on key deliverables for the Cognite SDK. In Cognite SDK JS, delivered a feature that enhances the Simulator Routines API with filtering by external IDs and strengthened API reliability through expanded test coverage. Implemented unit tests for both existing and non-existent IDs and performed a small refactor to improve test setup reuse and modularity. No customer-reported bugs were closed this month; the primary value comes from increased test coverage, greater API precision, and reduced QA risk.
