Changes

  • MultiCell now requires a cell count of one or more; the argument has no default by @henryiii in #1179
  • Filling an integer axis with a value that does not fit in an int raises ValueError instead of wrapping around by @henryiii in #1181
  • boost_histogram.numpy matches NumPy more closely: empty input, 1D histogramdd input, a single edge array in histogram2d, and range validation by @henryiii in #1178

Fixes

  • Encode UTF-8 for non-ASCII strings filled into StrCategory from a list or array by @henryiii in #1177
  • Avoid C++ aborts in axis metadata compare, MultiCell fill, and Boolean.value(); correct empty() for MultiCell by @henryiii in #1179
  • Keep growth axes valid after a fill or merge, and raise worker exceptions from a threaded fill by @henryiii in #1182
  • Correct UHI indexing with flow locators, disabled flow bins, and sliced group rebin by @henryiii in #1183
  • Give each axis copy its own metadata dict, and correct serialization, register(), integer-storage multiplication, transform equality, and repr by @henryiii in #1184
  • Avoid Boost indexed-range UB in rank-0 histograms and add Windows 3.14t testing by @ikrommyd in #1175

Performance

  • Cheaper fill argument variant, faster dtype dispatch, and move support for MultiCell by @henryiii in #1181
  • Release the GIL on copy, reset, compare, and in-place histogram operations by @henryiii in #1187

Documentation

  • Document that view() can be invalidated by a growing fill by @henryiii in #1182
  • Restore the Histogram API page on Read the Docs and correct the user guide and wheel table by @henryiii in #1180

Developer changes

  • Hold the GIL when copying or destroying Python objects in axes by @henryiii in #1172
  • Remove the dead regular_numpy Python axis, factor out pybind11 helpers, and correct stub drift and weak tests by @henryiii in #1185
  • Config and CI fixes: uv cache keys, workflow permissions and timeouts, and AGENTS.md commands by @henryiii in #1180
  • Test Python 3.15 now that NumPy wheels are on PyPI by @henryiii in #1170
  • Fix the scheduled wheel and weekly-update failures by @henryiii in #1173
  • Bump astral-sh/setup-uv from 9.0.0 to 10.0.1 by @dependabot in #1174
