I'm happy to hear about the new release !
Could someone put this information on the web ?
still dates to 2002 Aug (which is before 0.4 !!)
Or is this page the wrong page anyway -- I just end up there because google
points into that direction when you ask for 'numarray'
Thanks for the great work.

Subject: [Numpy-discussion] Numarray-0.5 released
> Release Notes for numarray-0.5
> 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
> I. ENHANCEMENTS
> 1. Universal Function Overhead Reduction
> The constant time overhead for most universal functions has been reduced
> by a factor of 10-20. This results in better performance for small
> 2. FFT mode and IRAF boundary modes added to Convolve.convolve2d
> There's now an FFT switch for the 2d convolution function in the
> Convolve package; when set to 1, convolution is performed via the FFT
> rather than using the naiive algorithm. In addition, convolve2d now
> supports boundary modes which are identical to IRAF's convolution
> 3. Numarray is now supported by f2py
> Numarray numerical arrays can now be used with f2py wrappers for
> Fortran code. To compile f2py wrapped extensions for numarray,
> use the switch -DNUMARRAY on the f2py command line. Support
> is currently limited to f77 and numerical arrays.
> II. BUGS FIXED
> 650926 exotic type coercions
> 653424 Convolve.boxcar boundary bug
> 653429 python setup.py build
> 654669 array index by list
> 655942 logical operator reductions
> 657058 inverse real fft bug
> 677796 byteswap not working
> 709956 error summing over large boolean arrays
> 710480 MLab.median makes unnecessary msort call
> 714537 conjugate function changes its argument
> for more details.
> III. CAUTIONS
> 1. Due to some module renamings, numarray-0.5 will not install
> correctly on top of an existing numarray installation. Before
> installing numarray-0.5 remove your old version of numarray.
> 2. Due to reorganization of the C-API, numarray extensions must be
> 3. For numarray-0.5 and up, the byteswap related methods have been
> a.byteswap() swaps but leaves byteorder alone
> a.togglebyteorder() Does "big" <-> "little"
> a._byteswap() now an alias for byteswap
> a._togglebyteorder() deleted
> 4. round() has been deprecated. Use around() instead.
> 5. Installing from source, the first time you run setup.py, you must
> specify --gencode, e.g.: python setup.py install --gencode
> Numarray-0.5 windows executable installers, source code, and manual is
> Numarray is hosted by Source Forge in the same project which hosts
> The web page for Numarray information is at:
> Trackers for Numarray Bugs, Feature Requests, Support, and Patches are

> numarray-0.5 requires Python 2.2.2 or greater.
