Version 0.2.1
=============
-Fixed some memory leaks and bugs in GUI.
-Added debian build files to directly create .deb package.
-Enhanced GTK GUI.

Sun Feb 20 01:37:28 EST 2005
Version 0.2.0
=============
-Better Win32 support. 
-Added sparse matrix routines for allmost all eigenvalue problems. 
 Now solution times are much lower and spurious solutions are almost
 avoided.

Sat Dec  4 00:30:47 EST 2004
Version 0.2.0-pre
=================
-Windows version using MFC released. It does not support all the features
of the Unix version, but it is much improved.

Tue Nov 16 22:52:24 EST 2004
Vesrion 0.1.9
=============
-Added a sparse matrix solver using Conjugate Gradients to solve Poisson Equation.
-Cleaned up some old code to fix FreeBSD compile problems.
-Fixed major bug in importing DXF files. Now pdnMesh can import versions R12 and 2000 files.
Mon Oct 18 17:57:04 EDT 2004
Version 0.1.7
============
-Added routine to calculate Charge on Dirichlet boundaries (patch by Werner Hoch)
-Refined the user interface, added tracker for the potential.
-Fixed minor bugs.

Sun Aug 22 16:00:12 EDT 2004
Version 0.1.6
=============
-Edge based solver fully operating.

Mon Aug 16 15:19:05 EDT 2004
Version 0.1.6-pre
=================
-This is a pre version before documentation is fixed for official version.
-New solvers for inhomogeneous waveguide problems are incorporated.

Fri Aug  6 20:15:49 EDT 2004
Version 0.1.5
=============
-Optionally uses LAPACK as eigensolver
-added gradient plots

Sat Jan 24 22:37:38 EST 2004
Version 0.1.4 (Pre)
=============
 -90% rewritten
 -An eigensolver is invluded to solve wave equation (homogeneous)
 -Uses GTK/gtkGLExt or Glut
 -The whole functionality of older version is yet to be incorporated


Mon Feb 18 16:47:44 EST 2002
Version 0.1.3
============
 Changes include:
   - Legend in contour/gradient display
	 - New colour scheme for contours, gradient
	 - Tutorial in DocBook format
	 - More commnand line options to display mesh, gradient 
	   by default
	 - Menu options to generate output files
	 - Zoom window display


Version 0.1.2
=============
 - 'd2m'a perl script to convert DXF files to ones that 
   can be fed to pdnmesh. In other words, you can define your 
   problem using a CAD program and save it as a DXF file (version 12 or lower).
 - Program had many loose ends fixed and optimised. Memory 
   requirement is cut down by half due to 
   lower triangular storage of global matrix.
 - Added a parser so that expressions can be given for rho.
 - Fixed awful errors in the configure script. 
   Now it is much cleaner and less error prone.
