Release Notes for numarray-1.1

Numarray is an array processing package designed to efficiently
manipulate large multi-dimensional arrays.  Numarray is modelled after
Numeric and features c-code generated from python template scripts,
the capacity to operate directly on arrays in files, and improved type
promotions.

I. ENHANCEMENTS

996177	Unsigned int type support limited

added Numeric C-API for more of the unsigned integer types.

986194	Add SMP threading

build/install with --smp to enable ufuncs to release the GIL during
their compute loops.  You have to supply your own threads and
partition your array computations among them to realize any SMP
benefit.

1016142	CharArray eval() too slow

CharArray.fasteval() was modified to use strtod() rather than Python's eval().  This makes it ~70x faster for converting CharArrays to NumArrays.  fasteval()
no longer works for complex types.  eval() is still slow but works for 
everything.

1008968	Add kroenecker product

II. BUGS FIXED / CLOSED

919297	Windows build fails VC++ 7.0
964356	random_array.randint exceeds boundaries	
984286	max.reduce of byteswapped array
985710	buffer not aligned on 8 byte boundary
989618	Document memmap.py (memory mapping)
990328	Object Array repr for >1000 elements
997898	Invalid sequences errors
1004600	Segfault in array element deletion
1005537	Incorrect handling of overlapping assignments in Numarray
1008375	Weirdness with 'new' method
1008462	searchsorted bug and fix
1009309	randint bug fix patch
1009462	matrixmultiply (a,b) leaves b transposed
1011456	numeric compatibility byteoffset	  
1015896	a.is_c_array() mixed int/bool results
1016140	argsort of string arrays

III. CAUTIONS

1. This release is binary incompatible with numarray-1.0.  All C extensions
which use the numarray C-API must be recompiled.  This incompatibility was
an unfortunate consequence of the fix for "numeric compatibility byteoffset".
