October 2025 focused on delivering platform enhancements, strengthening API stability, and improving observability for Qiskit Runtime. Key changes include private endpoint routing through /api/v1 with release notes, deprecation of RuntimeOptions with guidance for external users, and job tagging support for better traceability and cost attribution. A major release cycle was advanced with 0.43.0 prep featuring mid-circuit measurements, visualization tools, and virtual private endpoints, alongside backend/config updates. Logging improvements reduced account initialization verbosity and a 0.43.1 patch release prep was initiated. README updates now clarify service access and endpoints.

In January 2025, Qiskit/qiskit-ibm-runtime delivered meaningful reliability and developer-experience improvements across API surfaces, testing, and documentation. Key header/versioning enhancements tighten API interoperability with Content-Type, Accept, and IBM-API-Version headers, backed by unit tests ensuring header presence. The codebase also cleaned up deprecated pathways by removing backend.run() and migrating to V2 primitives, and introduced LocalRuntimeJob to align local testing with real backends. Maintenance outages handling is now more resilient with 503-aware messaging and streamlined error paths. Documentation updates clarify ZNE options, job filtering and EstimatorOptions, while testing infrastructure expanded with FakeFez/FakeMarrakesh backends and a fallback version in pyproject.toml to stabilize builds. Together, these changes improve reliability, developer experience, and time-to-value for runtime users.
