What's new
==========
This is a major release of PyTables and it is the result of more than a
year of accumulated patches, but most specially it fixes a nasty problem
with indexed queries not returning the correct results in some
scenarios. There are many usablity and performance improvements too.
In case you want to know more in detail what has changed in this
version, please refer to: http://pytables.github.io/release_notes.html

What it is?
===========
PyTables is a library for managing hierarchical datasets and
designed to efficiently cope with extremely large amounts of data with
support for full 64-bit file addressing. PyTables runs on top of
the HDF5 library and NumPy package for achieving maximum throughput and
convenient use. PyTables includes OPSI, a new indexing technology,
allowing to perform data lookups in tables exceeding 10 gigarows
(10**10 rows) in less than a tenth of a second.

Acknowledgments
===============
Thanks to many users who provided feature improvements, patches, bug
reports, support and suggestions. See the ``THANKS`` file in the
distribution package for a (incomplete) list of contributors. Most
specially, a lot of kudos go to the HDF5 and NumPy makers.
Without them, PyTables simply would not exist.

Hi Francesc,

on Windows I sometimes, not always, get a segfault during
test_basics.ThreadingTestCase. The crash is in the hdf5.dll during the
H5Pcreate function call at
<https://github.com/PyTables/PyTables/blob/release-3.2.0/tables/hdf5extension.pyx#L400>.
If there is no segfault, all tests pass. So far I could reproduce this
on Python 2.x, 32 and 64 bit, but not on Python 3.x. Could this be
related to <https://github.com/PyTables/PyTables/issues/359>?
