A new development release of ScientificPython (2.5.3) is now available 


It contains a reimplementation of the much-used Vector class in Pyrex, 
which is much faster than the original Python implementation based on 
arrays. The new vector objects also use less memory.

For MMTK users, this new ScientificPython release means important 
speedups for some operations. For example, the method centerOfMass() is 
about 2.5 times faster. Note however that energy evaluation and the 
minimizers and integrators are not accelerated at all, since they 
consist already of pure C code.

It is not necessary to update MMTK to profit from these speedups. It 
should even work with very old releases, but I have tested it only with 
MMTK 2.5.
