Qiskit Transpiler Service client release notes

0.11.1 (2025-05-14)

Bug fixes

  • Add Networkx package missing from the requirements (172)

0.11.0 (2025-03-25)

Upgrade notes

  • Prepare compatibility to Qiskit to v2.0.0 (minimum required 1.4.2) (168)

Deprecation notes

  • Remove backend_name from AIRouting and AISynthesis (165)

Other notes

  • Refactored type definitions by centralizing OptimizationOptions in qiskit_ibm_transpiler/types.py.

    What changed? - Introduced qiskit_ibm_transpiler/types.py to store shared type definitions. - Moved the OptimizationOptions type alias to types.py, eliminating redundancy. - Updated all relevant imports to use the centralized definition. - Ensured compliance with PEP 484 recommendations for type aliasing.

    How does this affect users? - No breaking changes; this is an internal refactor. - Any direct references to OptimizationOptions in multiple files now import it from types.py.

    Updated import path: .. code:: python

    from qiskit_ibm_transpiler.types import OptimizationOptions

    This improves code maintainability and makes future type updates easier.

    Fixes #166 <https://github.com/Qiskit/qiskit-ibm-transpiler/issues/166>. (166)

0.10.3 (2025-03-04)

Upgrade notes

  • Support qiskit 1.4.0 (fixed) (162)

New features

  • Added a __version__ attribute to qiskit_ibm_transpiler to enable version retrieval.

    What changed? - Introduced qiskit_ibm_transpiler/version.py for dynamically retrieving the package version. - Exposed __version__ in __init__.py, allowing users to access the installed package version. - If the package is installed normally, it will return the version as defined in importlib.metadata.version(). - If the package is being used from a Git repository without a release tag, it appends the commit hash.

    How to use the new feature? Users can now check the installed version by running:

    import qiskit_ibm_transpiler
print(qiskit_ibm_transpiler.__version__)

    Example outputs: - Installed via pip install qiskit-ibm-transpiler: 0.10.1 - Running from Git with a release tag: 0.10.1 - Running from Git without a release tag: 0.10.1.dev0+a1b2c3d
