[Pytables-announce] [ANN] PyTables and PyTables Pro 2.1.1 released

[Francesc A. <fa...@py...>]

Hi List,

I'm glad to announce the immediate availability of PyTables 2.1.1.  
This is a maintenance release that fixes some important problems with 
the previous 2.1 version.  Also, binaries for Windows and Python 2.6 
are provided now.  Those include the latest release of HDF5 (1.8.2), 
for an improved performance and stability.  The new binaries have been 
exhaustively tested, but tell me in case you are experiencing any 
problem.

And now, the official announcement:

===========================
 Announcing PyTables 2.1.1
===========================

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.

This is a maintenance release, so you should not expect API changes.
Instead, a handful of bugs, like `File` not being subclassable,
incorrectly retrieved default values for data types, a memory leak,
and more, have been fixed.  Besides, some enhancements have been
implemented, like improved Unicode support for filenames, better
handling of Unicode attributes, and the possibility to create very
large data types exceeding 64 KB in size (with some limitations).
Last but not least, this is the first PyTables version fully tested
against Python 2.6.  It is worth noting that binaries for Windows and
Python 2.6 wears the newest HDF5 1.8.2 libraries (instead of the
traditional HDF5 1.6.x) now.

In case you want to know more in detail what has changed in this

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 (and numarray!)
makers.  Without them, PyTables simply would not exist.
