Hi all,
I'm happy to hear about the new release !
Could someone put this information on the web ?
http://stsdas.stsci.edu/numarray/
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.
Sebastian

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
> promotions.
>
> 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
> arrays.
>
> 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
> function.
>
> 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
>
> See
> http://sourceforge.net/tracker/?atid=450446&group_id=1369&func=browse
> 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
> recompiled.
>
> 3. For numarray-0.5 and up, the byteswap related methods have been
> redefined:
>
> 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
>
> WHERE
> -----------
>
> Numarray-0.5 windows executable installers, source code, and manual is
> here:
