------------------
| PYFITS Release |
------------------

Space Telescope Science Institute is pleased to announce the
third and hopefully final candidate release of PyFITS 1.1.  
This release includes support for both the NUMPY and NUMARRAY 
array packages. This software can be downloaded at:

http://www.stsci.edu/resources/software_hardware/pyfits/Download

If you encounter bugs, please send bug reports to "help@stsci.edu".

We intend to support NUMARRAY and NUMPY simultaneously for a
transition period of no less than 6 months. Eventually, however,
support for NUMARRAY will disappear. During this period, it is
likely that new features will appear only for NUMPY. The
support for NUMARRAY will primarily be to fix serious bugs and
handle platform updates.

We plan to release the "official" PyFITS 1.1 version in a few weeks.

| Version |
-----------

Version 1.1rc3; May 17, 2007

-------------------------------
| Major Changes since v1.1rc2  |
-------------------------------

    * Fixes a bug in the creation of binary FITS tables
      on little endian machines introduced in release
      candidate 2.

-------------------------
| Software Requirements |
-------------------------

PyFITS Version 1.1rc3 REQUIRES:

       * Python 2.3 or later
       * NUMPY 1.0.1(or later) or NUMARRAY

---------------------
| Installing PyFITS |
---------------------
PyFITS 1.1rc1 is distributed as a Python distutils module.
Installation simply involves unpacking the package
and executing

% python setup.py install

to install it in Python's site-packages directory.

Alternatively the command

%python setup.py install --local="/destination/directory/"

will install PyFITS in an arbitrary directory which should
be placed on PYTHONPATH. Once numarray or numpy has been
installed, then PyFITS should be available for use under
Python.

| Download Site |

----------
| Usage  |
----------

Users will issue an "import pyfits" command as in the past.
However, the use of the NUMPY or NUMARRAY version of PyFITS
will be controlled by an environment variable called NUMERIX.

Set NUMERIX to 'numarray' for the NUMARRAY version of PyFITS.
Set NUMERIX to 'numpy' for the NUMPY version of pyfits.

If only one array package is installed, that package's version
of PyFITS will be imported.  If both packages are installed
the NUMERIX value is used to decide which version to import.
If no NUMERIX value is set then the NUMARRAY version of PyFITS
will be imported.

Anything else will raise an exception upon import.
