NumPy -- набор расширений популярного языка программирования, предназначенный для решения вычислительных задач.
В новом релизе:
- поддержка "очень больших" массивов на 64-битных системах (требуется Python 2.5)
- сборка без напильника ("out of the box") под cygwin
- документация по подключению внешних библиотек (C, C++, FORTRAN) посредством SWIG или Pyrex, с примерами
- новые функции .round, rint, square, reciprocal, ones_like

Changes from 1.0 ==> 1.0.1
Make ones work for compound types
Allow argsort and sort functions to take None as argument
Allow argsort method to take None as axis argument
Add order keyword to sort and argsort
Allow array_descriptor format to also use alignment.
Force objects with _fields_ attribute to use alignment
Support for recognize ctypes types as data-types.
Speed up Assign_Array dramatically using numarray-adapted code
Add a flags attribute to the dtype

Make the hasobject member of the PyArray_Descr structure a bit-flag so that behaviors of data-types can be controlled.
New features in f2py continued development.
Record arrays can now set field values using attribute access.
Allow user-defined data-types to use getitem and setitem instead of array scalar. Now, a data-type does not need a corresponding array scalar.
Remove usage of 'as' variable.

Fix setting arrays when mixing slice objects and index arrays for >2-d
Fix call of mmap with array scalars
Fixes in polysub and polyadd.
Fixes to name-space issues in compatibility layers
Fix startswith method on character arrays
Fix problem when fft called with invalid number of data-points
Fix reference count with ufuncs causing vectorize to behave poorly
Reference count fixes (for dtype objects and in f2py).
Fix problem if dgesdd does not compute optimal work size correctly
Fix OBJECT_argmax problem.
Added more tests and docstrings
