ANN: numarray-1.3.3

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

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)

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

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.

Problem installing matplotlib 1.3.1 with Python 2.7.6 and 3.3.3 (release candidate 1)
Hello, I tried to install matplotlib 1.3.1 on the release candidates of Python 2.7.6 and 3.3.3. I am on Mac OS X 10.6.8. Although the installation gave no problems, there is a problem with Tcl/Tk. The new Pythons have their own embedded Tcl/Tk, but when installing matplotlib it links to the Frameworks version of Tcl and TK, not to the embedded version. This causes confusion when importing matplotlib.pyplot: objc[70648]: Class TKApplication is implemented in both /Library/Frameworks/Python.framework/Versions/2.7/lib/libtk8.5.dylib and /Library/Frameworks/Tk.framework/Versions/8.5/Tk....

[RELEASED] Release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3
We're pleased to announce the immediate availability of release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3 . The main impetus for these releases is fixing a security issue in Python's hash based types, dict and set, as described below. Python 2.7.3 and 3.2.3 include the security patch and the normal set of bug fixes. Since Python 2.6 and 3.1 are maintained only for security issues, 2.6.8 and 3.1.5 contain only various security patches. The security issue exploits Python's dict and set implementations.

[RELEASED] Release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3
We're pleased to announce the immediate availability of release candidates for Python 2.6.8, 2.7.3, 3.1.5, and 3.2.3 . The main impetus for these releases is fixing a security issue in Python's hash based types, dict and set, as described below. Python 2.7.3 and 3.2.3 include the security patch and the normal set of bug fixes. Since Python 2.6 and 3.1 are maintained only for security issues, 2.6.8 and 3.1.5 contain only various security patches. The security issue exploits Python's dict and set implementations. Carefully crafted input can lead to extremely long computation times and denials of service. [1] Python dict and set types use hash tables to provide amortized constant time operations. Hash tables require a well-distributed hash function to spread data evenly across the hash table. The security issue is that an attacker could compute thousands of keys with colliding hashes; this causes quadratic algorithmic complexity when the hash table is constructed. To alleviate the problem, the new releases add randomization to the hashing of Python's string types (bytes/str in Python 3 and str/unicode in Python 2), datetime.date, and datetime.datetime. This prevents an attacker from computing colliding keys of these types without access to the Python process. Hash randomization causes the iteration order of dicts and sets to be unpredictable and differ across Python runs. Python has never guaranteed iteration order of keys in a dict or set,...
