Changes from 3.10.2 to 3.10.1

XXX version-specific blurb XXX

Changes from 3.10.1 to 3.10.0

Bugfixes

  • Fix version constraints for the numpy runtime requirements (:issue:`1204`). For a mistake it didn't allow to use PyTables with numpy 2.x.
  • Fix compatibility with PyPy (:issue:`1205`), Thanks to Michał Górny.

Improvements

  • Enforce numpy >= 2 as build constraint (see discussion in :issue:`1200`).
  • Use tuple of plain ints for chunk info coordinates. Thanks to Ivan Vilata-i-Balaguer.
  • Enable faulthandler in tables.tests.test_all. Thanks to Eric Larson.

Changes from 3.10.0 to 3.9.2

New features

  • New direct chunking API which allows access to raw chunk data skipping the HDF5 filter pipeline (cutting overhead, see "Optimization tips" in User's Guide), as well as querying chunk information (:PR:`1187`). Thanks to Ivan Vilata and Francesc Alted. This development was funded by a NumFOCUS grant.

Improvements

Bugfixes

  • Fix Windows AMD64 build issues with Bzip2 and C-Blosc2 libraries (:issue:`1188`). Thanks to Antonio Valentino and Eric Larson.
  • Fix typos and may other language errors in docstrings (:PR:`1122`). Thanks to Ko Stehner.
  • Fix Blosc2 filter not setting dparams.schunk on decompression (:PR:`1110` and :issue:`1109`). Thanks to Tom Birch.
  • Fix using B2ND optimizations when Blosc2 is not the only enabled filter; move Fletcher32 compression to end of pipeline when enabled (:PR:`1191` and :issue:`1162`). Thanks to Ivan Vilata and Alex Laslavic.
  • Fix broken internal passing of createparents argument in Leaf.copy (:PR:`1127` and :issue:`1125`). Thanks to Ko Stehner.
  • Re-enable relative paths in ExternalLink class (:PR:`1095`). Thanks to erikdl-zeiss.
  • Fix using prefix in heavy tests methods of test_queries (:PR:`1169`). Thanks to Miro Hrončok.
  • Fix TypeError when computing Blosc2 search paths with missing library (:PR:`1188` and :issue:`1100`). Thanks to martinowitsch, Padraic Calpin and Eric Larson.
  • Avoid overflow RuntimeWarning on NumPy expectedrows value (:PR:`1010`). Thanks to wony-zheng and Ivan Vilata.

Other changes

  • Add wheels for macOS ARM64 (Apple Silicon), set MACOSX_DEPLOYMENT_TARGET in Docker (:PR:`1050` and :issue:`1165`). Thanks to Clemens Brunner, Antonio Valentino, Maximilian Linhoff and Eric Larson.
  • Avoid illegal hardware instruction under macOS on M1/M2 with Rosetta and AMD64 wheels (:PR:`1195` and :issue:`1186`). Thanks to Antonio Valentino and Jon Peirce.
  • Produce nightly wheels (with HDF5 1.14.4), also uploaded to Scientific Python Anaconda repo. Wheels are also produced for PR workflows. Thanks to Antonio Valentino and Eric Larson (:PR:`1175`).
  • Wheels are no longer linked with the LZO library to avoid licensing issues (:PR:`1195`). Thanks to Antonio Valentino.
  • Hash-pin dependencies on wheel workflows to increase build procedure security, with support for Dependabot and Renovatebot updates (:PR:`1085` and :issue:`1015`). Thanks to Joyce Brum and Diogo Teles Sant'Anna.
  • Hash-pin GitHub action versions in wheels workflow. Thanks to Antonio Valentino.
  • Update ReadTheDocs configuration to version 2 (:PR:`1092`). Thanks to Maximilian Linhoff.
  • Assorted fixes to b2nd benchmark, with new results. Thanks to Ivan Vilata.
  • Point users to example code to handle "Selection lists cannot have repeated values" exception (:PR:`1161` and :issue:`1149`). Thanks to Joshua Albert.
  • Remove unused getLibrary C code. Thanks to Antonio Valentino.
  • Update included C-Blosc to 1.21.6 (:PR:`1193`). Thanks to Ivan Vilata.
  • Update included HDF5-Blosc filter to 1.0.1 (:PR:`1194`). Thanks to Ivan Vilata.
