[Pytables-announce] PyTables 0.5.1 to solve a problem with 0.5

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

PyTables 0.5.1
--------------

This is a maintenance release of PyTables. Due to a problem with an
optimization in PyTables 0.5, it does not work with numarray 0.4
(although it works just fine with numarray 0.5). Because Todd Miller
has already warned me that this optimization is not safe, I am
*disabling* it in this release. The consequence is that the 20% of
improvement during reading tables has almost evaporated to a rather
small 4%, but that's life!.

If you already have installed PyTables 0.5, I strongly suggest you to
upgrade to 0.5.1, even if you are already using numarray 0.5. I will
try to further investigate the problem, and, if a good solution is
found, I will re-activate the optimization in a future release.

Another new thing you can find in 0.5.1 is that the use of "UInt64"
data types has been removed (it has been replaced by the "Int64" type)
of the tutorial chapters in User's Manual because the Windows version
does not support such a type (due to MSVC compiler limitations). Now,
the tutorial section should run fine in all the supported platforms
(even Windows).

My apologies for being a sinner and trying to optimize too soon ;-)
