2.11.0

2.11.0 (August 21, 2026)

Major changes

• Incorporated HDMF Common Schema 1.10.0, which changed MeaningsTable.target from a link to an object-reference
  attribute (dtype with reftype: object, target_type: VectorData). This is a breaking change for files
  written with the 1.9.0 definition of MeaningsTable, which was introduced in NWB 2.10.0.

Minor changes

• Added optional time_before_peak_in_ms attribute (float32) to Units.waveform_mean,
  Units.waveform_sd, and Units.waveforms to record the time from the start of the waveform to the spike peak,
  i.e., the alignment point used during spike sorting. sampling_rate and the number of samples give
  the duration of the waveform window but not where the spike event falls within it. (#667, #709)
• The unit attribute on Units.waveform_mean, Units.waveform_sd, and Units.waveforms is a
  default_value of volts rather than a fixed value, so waveforms may be stored in other units. (#707)

Bug fixes

• Fixed copy-paste error in VoltageClampSeries.capacitance_slow unit attribute doc, which incorrectly
  referenced capacitance_fast.
• Fixed IntervalSeries.data resolution and unit attribute docs, which were verbatim copy-paste from
  AnnotationSeries and incorrectly described the field as storing annotations.
• Fixed IndexSeries.indexed_images link doc, which referenced the non-existent dataset name
  'ordered_images'; corrected to 'order_of_images' to match the actual field in Images.
• Fixed ImagingPlane.device link doc, which incorrectly described the device as being used to
  "record from this electrode"; updated to reflect optical physiology imaging context.
• Fixed RoiResponseSeries.rois doc, which referenced the non-existent type ROITable; corrected
  to PlaneSegmentation to match the actual type used for ROI segmentation results.

Documentation improvements

• Corrected grammar, spelling, and punctuation errors across all core schema doc strings, including
  typos, broken syntax, missing terminal periods, inconsistent DEPRECATED. tag formatting,
  informal and improper abbreviations, missing words and wrong words, subject-verb disagreement, and
  missing articles. (#704)
