PDL

wmpeg() from PDL::IO::Pic now uses the new ffmpeg back-end and can create many additional file formats beyond MPEG alone, including MP4 and animated GIF. The deprecated Karma imaging library support code has been removed from the PDL distribution. There were lots of improvements to the documentation and overall usability. Many bugs were fixed.

This is mainly a bugfix release with a number of
small enhancements. FITS I/O now supports binary
tables. Many improvements were made to the PLplot
interface. PDL::Transform was upgraded. A new
"pdl" command-line entry to the perldl shell
allows #!-style scripting (so you can re-use your
journal files verbatim). Various improvements were
made for 64-bit systems. This release also
deprecates the use of the 5.6 versions of perl.
The use of the 5.8 series is recommended.

This is mainly a bugfix release. The code has been
updated to remove the warnings produced by perl
5.8.1. The PLplot interface has been updated for
version 5.2.1. The m51.fits file has been replaced
with a freely-distributable image from the Hubble
Heritage archive.

This release requires Perl 5.6.0 and the Filter and Text::Balanced modules. Highlights include the improved slicing syntax (PDL::NiceSlice), powerful N-dimensional indexing and slicing, improved support for GSL, support for the PLPlot graphics library, coordinate transformation and image resampling, and the ability to use mutli-line constructs in the perldl shell.

PDL now compiles with perl 5.8.0. Speed improvements were made when generating piddles from a Perl array reference. PDL storage/retrieval is now possible using the PDL::IO::Storable module. The GNU Scientific Library Special Functions are now available from the PDL::GSL::SF module, and the % operator now matches the behavior of the Perl % operator.
