The PDL development team is pleased to announce
the official release of PDL-2.006 and an updated
draft of the PDL Book to accompany its release.
Of specific note:
* PDL VERSION numbers now use single decimal
format. This will be the standard going forward.
* PDL now has three graphics options that build on
all supported PDL platforms (thanks to work by
Craig DeForest and David Mertens and a host of
others):
- PDL::Graphics::Gnuplot using the gnuplot program
- PDL::Graphics::Prima based on the Prima toolkit
and
- PDL::Graphics::Simple a basic 2-D graphics layer
that can use many of the existing PDL graphics
modules with a uniform syntax.
* ASPerl build issues have been resolved thanks
to relentless testing, verification and fixes by
Rob/sisyphus and other win32 PDL users.
As always, go to http://pdl.perl.org for information
about all things PDL and how to get PDL for your
platform.
Enjoy!

Release Notes for PDL 2.006 --------------------------
+---------------------------------------------------------------+
| BE WARNED: This release includes an update to the internal, |
| C-level PDL API for PDL versions 2.4.10 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:
* Change to the version number scheme used for PDL
from the dotted-integers format back to plain old
decimal numbers.
Unfortunately, PDL has used both alternatives before
and in an inconsistent, out-of-order way. With this
release, the current version will also be the most
recent version with respect to both numbering schemes.
For more details see David Goldens blob post on
the topic and the pdl-porters list discussion:

* PDL-2.006 also showcases the demos of two new PDL graphics
modules in the perldl/pdl2 shells:
- PDL::Graphics::Gnuplot
http://search.cpan.org/~zowie/PDL-Graphics-Gnuplot-1.4/
- PDL::Graphics::Prima
http://search.cpan.org/~dcmertens/PDL-Graphics-Prima-0.13/
Both modules install on all supported PDL platforms. A
recent addition is PDL::Graphics::Simple which provides
a uniform presentation to the variety off available PDL
plot/view/print options.
- PDL::Graphics::Simple
http://search.cpan.org/~zowie/PDL-Graphics-Simple-1.004/README.pod
Let us know how they work for you. As they are
relatively "young" contributions your feedback and
questions are always welcome.
* PDL Distribution related updates:
- Fixes a build issue for PDL at ASPerl
- Many fixes for debian distributions.
- PDL::IO::NDF has been moved to its own
distribution on CPAN. This could affect
upgrades from older PDL installs.
Highlights:
* New support for reading IDL format files via PDL::IO::IDL.
* Added an unpdl method which is (roughly) the inverse
operation of pdl (Joel Berger).
* Updated polyfill and polyfillv routines to the algorithm
from pnpoly: more accurate on edge pixels and faster due
to its PP implementation (Tim Haines).
* Added Boundary=>'Replicate' option to conv2d and med2d (chm).
* Support for new additional random number generators to
PDL::GSL (John Lapeyre).
* Add lgamma support for MinGW-built perls with tests
to match (sisyphus).
* Many improvments to docs and their generation from
PDL sources. Specific new functionality support:
- Newly refactored docs engine using core perl
modules rather than PDL-only ones (Joel Berger)
- New FullDoc key added to PDL::PP makes writing CPAN
friendly .pd files much, much easier (David Mertens).
- New PDL::Doc::add_module() routine to add an external
module's POD (with PDL::Doc conventions) to the PDL
docs on-line database (Craig DeForest).
* Many bugs fixed, some even before a ticket could be opened!
- Sf.net bug #3607936: Fixed a bug causing crashes
due to using inplace with a duplicate argument.
- Sf.net bug #3603249: AutoLoader leaks $_ into local
context, reported and fixed by Craig.
- Sf.net bug #3588182: Fixed hist() handling of the case
of fractional steps in integral input data types.
- Sf.net bug #3563903: Fixed bug in PNG format detection
on win32 platforms.
- Sf.net bug #3544682: Fixed error report bug in perldl
that resulted from a change in the way perl handles
eval exception reporting.
- Sf.net bug #3539760: qsort[vec] are now inplace aware.
- Sf.net bug #3518190: Potential fix for t/gd_oo_tests.t
test crashes.
- Sf.net bug #3515759: Work around for PDL::GIS::Proj
build failures with proj-4.8.0.
- Sf.net bug #3479009: Fixed dummy() to generate a
valid syntax for the underlying call to slice().
- Sf.net bug #3475075: Fixed 16-bit PNM raw format handling.
- Added warning if conv1d is used on a piddle with
the badflag set.
- Fix NaN sign issues as reported (and fixed!) by
Matthew McGillis with contributions by Sisyphus.
- Fix rim() 3-arg form. Added tests to support and
verify the development.
- Fixed a problem with multiple windows and imag2d
and imag2d_update.
* The PDL shells keep getting better:
- New feature in perldl and pdl2 where a pattern matching
the PDL shell prompt (in $PERLDL::PREFIX_RE) will get
stripped off of input lines before eval. This makes it
easier to cut-and-paste example text from PDL shell
sessions or from the PDL Book into an active session.
- Added a demo for PDL::Graphics::Prima to the PDL shells.
- Added a demo for gnuplot to the PDL shells.
- The p shortcut to display output in the PDL shells has
been reverted to its previous 2.4.10 behavior. If you
wish it to be an exact alias for print just override
in your .perldlrc or local.perldlrc file.
