Release Notes for PDL 2.008 -----------------------------

 +---------------------------------------------------------------+
 | BE WARNED:  This release includes an update to the internal,  |
 | C-level PDL API for PDL versions 2.007 and earlier.  This     |
 | will require that you re-build any PP or XS modules.  Do not  |
 | upgrade or install over an existing PDL installation unless   |
 | you are prepared to do so!!!                                  |
 +---------------------------------------------------------------+

General Notes:

 * This is PDL-2.008!  Yay!

 * perl 5.10.x is now the minimum version of perl
   supported by PDL-2.008 and later.

 * 50 sf.net bug tickets closed/fixed since PDL-2.007!

 * Partial 64bit indexing support with some fixes to
   remaining issues.  Full 64bit support for perl modulus
   operater ('%') is in progress.
 
 * Major clean up and rework of the core PDL computation
   code, the build process, test suites, and updating to
   reflect more of the best practices for perl module
   development.
 
 * The PDL development has moved to github and now has
   added continuous commit testing via the Travis-CI
   framework.  The git workflow is now inline with
   current practices and it is expected that this will
   allow more contributions and "eyes on the code".

Highlights:

 * PDL::FFTW is no longer part of the PDL Core.
   Please use PDL::FFTW3 from CPAN (Dima Kogan)
   with Alien::FFTW3 support (Craig DeForest)

 * New improved vsearch functionality, interfaces,
   and documentation (Diab Jerius)
 
 * PDL::IO::Storable now robust against version, platform
   endianness, and supports the new 64bit PDL_Indx data
   type (Dima Kogan)

 * Clean up of PDL/Basic/Core code to remove cruft and
   to simplify the evolution to a coming improvements
   (Craig DeForest)
 
 * Major clean up, de-crufting, and streamlining of the
   entire PDL ExtUtils::MakeMaker build process (Ed J)
 
 * Standardizing and updating the entire PDL test suite
   to a common basis (use Test::More) and coding to more
   consistent best practices.  E.g., use strict
   This is a huge (ongoing) effort but a comprehensive
   test suite is needed for regression tests to validate
   compatibility of coming PDL3 architecture changes.
   (Zakariyya Mughal)

 * You can now call the PDL::Graphics2D twiddle()
   routine with an argument of 0 or 1 (i.e., false
   or true) to set whether the twiddle loop is run.

 * Library dependency detection improvements including
   PROJ4 and GD.  A number of improvements in this for
   strawberry perl on windows (kmx)
 
 * The PDL distribution process now generated the
   documentation for the modules using the automated
   code generation process.  This makes all the PDL
   docs available on http://search.cpan.org and on
   http://metacpan.org for your web browser. (kmx)

 * Improved support to build XS/C extensions: (Ed J)
   - You can now: "use Inline with => 'PDL';", see PDL::API
   - You can, in your module's Makefile.PL:
     "$p = new ExtUtils::Depends 'MyMod', 'PDL'"
