Changes from 3.5.3 to 3.6.0

PyTables 3.6 no longer supports Python 2.7 see PR #747.

Improvements

  • Full python 3.8 support.

  • On Windows PyTables wheels on PyPI are linked to pytables_hdf5.dll instead of

hdf5.dll to prevent collisions with other packages/wheels that also vendor hdf5.dll. This should prevent problems that arise when a different version of a dll is imported that the version to which the program was linked to. This problem is known as “DLL Hell”. With the renaming of the HDF5 DLL to pytables_hdf5.dll these problems should be solved.

Bugfixes

  • Bugfix for HDF5 files/types with padding. For details see gh-734.

  • More fixes for python 3.8 compatibility: Replace deprecated time.clock with time.perf_counter Thanks to Sergio Pascual (sergiopasra). see gh-744 and PR #745.

  • Improvements in tests as well as clean up from dropping Python 2.7 support. Thanks to Seth Troisi (sethtroisi).
