What’s New¶

Qanary Changelog¶

Python 3.12 is no longer supported. QCUtils requires 3.13.
Qcutils.buffered.instruments is removed. Import the node classes from qcdrivers.buffered. instead; QCUtils keeps the buffered sweep orchestration.
The modules qcutils.live_server and qcutils.shared.live_db are removed. Live publishing goes through the qimchi-connect package, which QCUtils now depends on. Measurement scripts are unaffected.
These helpers are renamed with a leading underscore: qcutils.sweep.stepper, qcutils.logger.setup_logging, qcutils.measure.{register,get,unregister}_memory_store, qcutils.measure.get_live_dataset_info, qcutils.measure.list_live_measurements, and qcutils.buffered.sweep.{parse_bufsweep_tree,arm_instruments,fetch_results, abort_instruments,fetch_dependents_tree}. The measurement-script API is unchanged.

[Feature] Introduced dataset utilities (datasets.py) for common measurement operations
[Feature] Reworked dataset storage pipeline:
- Use Zarr for live/in-progress measurements to avoid file locking issues
- Finalize and export to NetCDF (.nc) at measurement completion
- Added support for partial .nc snapshots during sweeps (experimental; may fail on Windows)
[Feature] Added update_measurement_path and improved disk finalization logic for better artifact handling and DB consistency
[Feature] Increased WebSocket server max message size to 100 MB for large dataset handling
[Fix] Fixed measurement tabulation issues
[Fix] Fixed circular sweep behavior
[Fix] Fixed segmented sweep handling
[Fix] Fixed MultiChannelParameter handling and related instrument behavior
[Fix] Fixed measurement bugs (general measurement stability improvements)
[Fix] Fixed instrument snapshot errors when parameters are np.ndarray
[Fix] Added JSON sanitization for NumPy types in WebSocket responses
[Misc] Moved live_db module to shared location for reuse across projects
[Misc] Updated dependency versions (including websockets > 16.0, zhinst compatibility updates, and numcodecs downgrade)
[Misc] Internal refactors and consolidation of dataset-related changes
[Misc] Added and reorganized QCoDeS parameter class support
[Misc] General cleanup, refactoring, and merge of multiple feature/fix branches (datasets, sweeps, measurement handling)
