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, arrays of heterogeneous records, string arrays, and in-place operation on memory mapped files. ========================================================================= Release Notes for numarray-1.3.3 I. ENHANCEMENTS None. 1.3.3 fixes a fatal problem with embedding numarray and loading it more than once. It also fixes some numarray memory leaks associated with restarting the Python interpreter. II. BUGS FIXED / CLOSED 1233431 Add 'type' to fromfunction() 1230490 Numarray: integer overflow in sum() is not detected 1216688 ufunc's ignoring complex operand 1213675 Problems embedding after 1.1.1 1209946 Mac OS-X --use_lapack 1212975 numarray.fromfunction(...) misbehavior 1209929 config.h and Python-2.2 1235278 Add -lm to numarray link lists See http://sourceforge.net/tracker/?atid=450446&group_id=1369&func=browse for more details. ========================================================================= Release Notes for numarray-1.3.2 I. ENHANCEMENTS None. 1.3.2 fixes the problem with gcc4 on Mac OS-X 10.4 Tiger II. BUGS FIXED / CLOSED 1193125 Build failure on Mac OS 10.4 (Tiger) 1195370 numarray1.3.1 setup.py broken See http://sourceforge.net/tracker/?atid=450446&group_id=1369&func=browse for more details. ========================================================================= Release Notes for numarray-1.3.1 I. ENHANCEMENTS None. 1.3.1 fixes the problem with gcc-3.4.3 II. BUGS FIXED / CLOSED 1152323 /usr/include/fenv.h:96: error: conflicting types for 'fegete 1185024 numarray-1.2.3 fails to compile with gcc-3.4.3 1187162 Numarray 1.3.0 installation failure See http://sourceforge.net/tracker/?atid=450446&group_id=1369&func=browse for more details. ========================================================================= Release Notes for numarray-1.3.0 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, arrays of heterogeneous records, string arrays, and in-place operation on memory mapped files. I. ENHANCEMENTS 1. Migration of NumArray.__del__ to C (tp_dealloc). Overall performance. 2. Removal of dictionary update from array view creation improves performance of view/slice/subarray creation. This should e.g. improve the performance of wxPython sequence protocol access to Nx2 arrays. Subclasses now need to do a.flags |= numarray.generic._UPDATEDICT to ensure that dictionary based attributes are inherited by views. NumArrays no longer do this by default. 2. Modifications to support scipy.special. 3. Removal of an unnecessary getattr() from ufunc calling sequence. Ufunc performance. II. BUGS FIXED / CLOSED 1179355 average() broken in numarray 1.2.3 1167184 Floating point exception in numarray's dot() 1151892 Bug in matrixmultiply with zero size arrays 1160184 RecArray reversal 1156172 Incorect error message for shape incompatability 1155538 Incorrect error message when multiplying arrays See http://sourceforge.net/tracker/?atid=450446&group_id=1369&func=browse for more details. III. CAUTIONS This release should be backward binary compatible with numarray-1.1.1 and 1.2.3.
