Release notes for PDL 2.3 -------------------------------
 
 Summary of Changes
   - A nicer slicing syntax for PDL added via the new 
     PDL::NiceSlice module.
   - Inline::Pdlpp module added, which enables in-line
     PDL::PP definitions. (i.e. no Makefiles, building
      hassles for creating PP code)
   - A Multitude of bug fixes, doc updates, and other
     changes.
     
  Note:Support for perl version 5.005 and previous is 
  limited in this release. Perl 5.6.0 or greater is
  recommended for full PDL functionality.
	
  See the Changes file for a detailed list of changes.

  See the Changes file for a detailed list of changes.
  
Release notes for PDL 2.2 -------------------------------

Major Changes:

  - 'Bad' Value Support added. With this option compiled-in, certain
     values in a PDL can be designated as 'Bad' (i.e. missing, empty, 
     etc). With this designation, most PDL functions will properly 
     ignore the 'Bad' values. See PDL::BadValues for details.
     
  - PGPLOT interface rewritten. New Features:
      - Interactive cursors (cursor)
      - Text on plots       (text)
      - Legends             (legend)
      - Circles, Rectangles, Ellipses
      - Multiple plot windows, one can jump from panel to panel when
        the window is divided in several.
      - More control over options - see PDL::Graphics::PGPLOTOptions for
        details.
      - New Examples in Example/PGPLOT.

   - Major updates to the Tri-D Code. Now requires perl 5.6 for TriD.
    
   - 'Reduce' function added. This provides a consistent interface to the
     projection routines (sumover, average, etc). See PDL::Reduce.
     
   - Improved OpenGL detection during 'perl Makefile.PL

   - pdldoc command added. This allows you to look up PDL 
     documentation similar to the perldoc command. 
     
   - Perl 5.6 is now recommended for PDL 2.2. It will still work 
     with perl 5.005, but some of the extra libs won't be compiled
     ( like Graphics/TriD).
  
Many other changes. See the Changes file for a detailed list of changes.

Release notes for PDL 2.1 -------------------------------

Major Changes:
  - Speed Increase. Most PDL functions are now done totally
    in C-code, without any perl wrapper functions as was done
    with previous versions. The speedup will be most noticeable
    for operations on many small PDL arrays.
  - Mem Leaks Fixed.
  - Added a consistent, Object-Oriented interface to the 
    various interpolate functions in PDL. (PDL::Func, 
    See Lib/Func.pm).
    
See the Changes file for a detailed list of changes.



Release notes for PDL 2.005 -----------------------------

A bugfix release to fix 2.004 problems with PGPLOT changes
and perl 5.6.0.

The following notes from 2.004 still apply:
                                             
*IMPORTANT NOTE*: Due to changes to the PGPLOT module, 'use
PDL::Graphics::PGPLOT' has been removed from PDL.pm (i.e. in scripts
and within perldl you now need to explicitly say 'use
PDL::Graphics::PGPLOT'). Additionally, it needs Karl's new 2.16
release of the PGPLOT module (available from CPAN).

Notable additions are a module for operations on complex piddles
(PDL::Complex), a subtype of PDL which allows manipulation of byte
type PDLs as N dimensional arrays of fixed length strings (PDL::Char)
and a Levenberg-Marquardt fitting module (PDL::Fit::LM).

Bug reports and patches to the relevant places on sourceforge, please.
