Release notes

2026.3.17

New Features:

• Decoding transceiver data from Matterhorn10 transformed_data = aare.transform.Matterhorn10Transform(num_counters=2, dynamic_range=16)(data)
• Expanding 24 to 32 bit data aare._aare.expand24to32bit(data, offset=4)
• Decoding digital data from Mythen 302 transformed_data = aare.transform.Mythen302Transform(offset=4)(data)
• added aare.Interpolator.transform_eta_values. Function transforms $\eta$-values to uniform spatial coordinates. Should only be used for easier debugging.
• New to_string, string_to
• Added exptime and period members to RawMasterFile including decoding
• Removed redundant arr.value(ix,iy...) on NDArray use arr(ix,iy...)
• Removed Print/Print_some/Print_all form NDArray (operator << still works)
• Added const* version of .data()
• reading multiple ROI's supported for aare.
  • Use aare.RawFile.read_roi(roi_index=0) to read a specific ROI for the current frame
  • Use aare.RawFile.read_rois() to read multiple ROIs for the current frame
  • Use aare.RawFile.read_n_with_roi(num_frames = 2, roi_index = 0) to read multiple frames for a specific ROI.
  • Note read_frame and read_n is not supported for multiple ROI's.
• Building conda/pypi pkgs for python 3.14. Removing 3.11 builds.

Bugfixes:

• multi threaded cluster finder doesnt drop frames if queues are full
• Round before casting in the cluster finder to avoid biasing clusters by truncating
