I summarized the current CVS progress and
updated the release notes for 2.4.3. Below is
just the 2.4.3 stuff FYI. Known_Problems can
follow but maybe that would be better filled in
after the official pre-release testing.

Release notes for PDL 2.4.3 ------------------------------
General Notes:
- again, mainly a bugfix and polishing release.
- builds out-of-the-box on cygwin and win32 build environment
has been significantly improved
- perl 5.6.x is now deprecated; 5.8.x is recommended. Support
for 5.6.x may go away in future versions.
Summary of Changes:
- PDL now builds under cygwin on windows PC including
TriD(OpenGL) 3D graphics and PGPLOT and PLplot 2D graphics
support. See PDL/cygwin files README and INSTALL for
details and how to build/install external dependencies.
- The win32 build has been improved. See PDL/win32/INSTALL
for details.
- Many fixes from the Debian build patches have been
incorporated. See PDL/debian for specifics.
- 64bit platform build has been improved.
- New functionality, functions and modules:
* Bad value support has been extended to per-PDL bad
values as an experimental feature. To use, configure
WITH_BADVAL => 1 and BADVAL_PER_PDL => 1 in perldl.conf
before building.
* PDL::GSL::INTEG now supports the calculation of
nested integrals
* New function tcircle (threaded circle) added to
PDL::Graphics::PGPLOT This draws multiple circles in
one go (see also tpoints and tline)
* Added set operation routines for pdls treated as sets
(help setops).
* PDL::IO::GD module interface to the GD runtime image
libaray (http://www.boutell.com/gd/) has been integrated.
* The PDL::GIS::Proj and PDL::Transform::Proj4 modules
to interface to the PROJ4 Cartographic Projections
Library (http://proj.maptools.org/) have been added.
* PDL::IO::HDF provides an interface to the HDF4
library (http://hdf.ncsa.uiuc.edu/).
- The PDL test suite (i.e. tests in in PDL/t) has been
enhanced. Coverage has improved and output diagnostic
messages are more useful. Test::More is becoming the
preferred test module. The vanilla Test and Test::Simple
may be deprecated in the future.
- PDL core code has been fixed to address valgrind-detected
errors and to enable better bad value support including the
new experimental per-PDL bad values. These changes will
require a re-build/install of any external modules using
the C interface of PDL. See perldl.conf to configure the
new bad value support.
- Several TriD graphics build problems have been resolved.
The TriD rotation bug has been fixed.
- Many other bug fixes too numerous to mention. See the
PDL/Changes file for details.
- Multiple fixes and additions to PDL documentation as well
as the PDL::FAQ.
