Release notes for PyTables 3.5 series
=======================================
:Author: PyTables Developers
:Contact: pytables-dev@googlegroups.com
.. py:currentmodule:: tables
Changes from 3.5.1 to 3.5.2
===========================
- Fixed compatibility with python 3.8: Fixed `Dictionary keys changed during
iteration` RuntimeError while moving/renaming a node.
Thanks to Christoph Gohlke for reporting and Miro Hrončok for help with
building PyTables for python 3.8alpha (cython compatibility).
See :issue:`733` and :PR:`737`.
- Fixed a bug in offset calculations producing floats instead of ints
affecting python 3. See :PR:`736`. Thanks to Brad Montgomery.
Changes from 3.5.0 to 3.5.1
===========================
- Maintenance release to fix how PyPi repo is handling wheel versions.
Changes from 3.4.4 to 3.5.0
===========================
Improvements
------------
- When copying data from native HDF5 files with padding in compound types,
the padding is not removed now by default. This allows for better
compatibility with existing HDF5 applications that expect the padding
to stay there.
Also, when the `description` is a NumPy struct array with padding, this
is honored now. The previous behaviour (i.e. getting rid of paddings) can
be replicated by passing the new `allow_padding` parameter when opening
a file. For some examples, see the new `examples/tables-with-padding.py`
and `examples/attrs-with-padding.py`. For details on the implementation
see :issue:`720`.
- Added a new flag `--dont-allow-padding` in `ptrepack` utility so as to
replicate the previous behaviour of removing padding during file copies.
The default is to honor the original padding in copies.
- Improve compatibility with numpy 1.16.
- Improve detection of the LZO2 library at build time.
- Suppress several warnings.
- Add AVX2 support for Windows. See :PR:`716`. Thanks to Robert McLeod.
