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: http://www.dagolden.com/index.php/369/version-numbers-should-be-boring/ http://mailman.jach.hawaii.edu/pipermail//pdl-porters/2013-February/005343.html * 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. * The PDL Book has been updated for PDL-2.006. If you are new to PDL, it is highly recommended. Try the First Steps with PDL sample chapter. https://sourceforge.net/projects/pdl/files/PDL_2013/PDL-Book/ 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.
