The PDL-2.4.4 release has been uploaded to CPAN
and should appear at a mirror near you within the next
few days. The release features enabled bad value
support, many bugs fixed, and improved support on
many platforms.
Enjoy!

Release notes for PDL 2.4.4 ------------------------------
General Notes:
- Bad value support is now enabled by default for
PDL builds. This feature allows simpler handling
of missing or invalid data during processing.
For example, missing pixels could be interpolated
across. Calculations could be skipped for
missing data points...
Edit the perldl.conf file to turn off bad value
support before compiling if needed.
- This release includes significant improvments
in portability, enhancements in functionality,
and *many* bugs fixed.
- PDL::Graphics::TriD modules for 3-D and image
visualization are being refactored for improved
portability and performance. Preliminary hooks
are in PDL-2.4.4 to support the new functionality.
Announcements to the perldl mailing list will be
made when the PDL::Graphics::OpenGL::Perl and
Term::ReadLine::FreeGLUT suport is on CPAN.
- Builds out-of-the-box on cygwin and win32
- perl 5.6.x is explicitly required to configure and
will go away in future versions. 5.8.x and above
are the recommended versions
Summary of Changes:
- Improve uuencode support in Dumper for additional OSes
such as *BSD varieties that may need additional options
to prevent stripping of the leading slash in pathnames
including: darwin, netbsd, openbsd, freebsd, and dragonfly.
- Updated more PDL tests to use the recommended Test::More
- Updated PDL::Graphics::PLplot build support for more 5.9.0
specific features
- AutoLoader ~ expansion has been updated to conform more
closely to the ~ expansion in the bash shell
- Better checks for a valid PROJ4 build environment are now
performed before attempting to compile PDL modules using it
- PDL now builds and runs on perl-5.10.x
- The perldl shell has added support for using FreeGLUT for
display in analogy with the existing Tk event loop support.
This enables refactoring of the TriD modules to use the
Perl OpenGL module (a.k.a. POGL) instead of the internal,
and deprecated, PDL::Graphics::OpenGL et. al.
- The perldl acquire/filter/execute loop is now $_-safe by
using $lines instead of $_ for all the central modifications.
Avoids problems with some AUTOLOAD functions that leaked $_.
- Removed ExtUtils::F77 from the required prerequisites for
PDL to improve the buildability on platforms without an
available fortran compiler. If you have a fortran compiler
and EU::F77 installed, PDL::Slatec will be built.
- zeros function added as an alias for the zeroes function
- Many warning messages that were not actually problems have
been quieted, especially many pointer to int conversion messages
- Added $PERLDL::HISTFILESIZE to allow configuration of the number
of lines of history to be saved by the interactive PDL shell.
- Fixed implementation of the pctover() function to address bug
#2019651 on sf.net. Added explicit documentation in the code
on the algorithm being used.
- Various updates to the PDL FAQ
- Implemented a PDL interface to the Minuit minimization library
from CERN
- Removed circular dependency in PDL Makefile.PL Makefile generation
process which caused builds with some versions of make to fail
- Multiple fixes to enhance configuration and build for win32
- Added basic table-inversion to t_lookup for PDL::Transform
- Fixed problem in uniqvec() where it failed to generate a correct
result if all the input vectors were the same, fixed bug #1869760
- Add improved 16-bit image support for IO with rpic() and wpic()
provided you have a recent version of the NetPBM library that
supports 16-bit images
- Enabled building of GSL on Win32.
