Changes to 0.5.5 from 0.5.6

* Geometric engine rewriten from scratch. It is very tiny now, more
  easy to maintain and extend. The save format of the geometric figure
  and macro-construction has changed. Look drgeo/DevelopersFAQ to know
  more.

* Libxml 2.0.0 is now needed but Libglade need libxml 1.x.x also (this
  is what says "gnome-config --clfags libglade"). So you will need both
  development version I guess. Strange, I alway believe Libglade has its
  own parser.

Changes to 0.4.6

* accept more different formats of floats in scientific notation
* fix problems with hangs on help and large dialogs

Changes to 0.4.5

* modular arithmetic support (e.g. "expr mod n")
* different parsing of files on the load line (you can now pass multiple
  files with quotes everywhere, just like in a shell
* plugin toplevel command to load plugins from command line
* more function descriptions for the help command
* possibility to run gel function from inside of genius code
* exp function now behaves properly for matrices (sort of)
* setting calculator parameters is now more natural, just as setting variables
* option for maximum line output length for expression output, and for
  maximum number of errors printed
* backdivision for matrices (e.g. X=A\B means A*X=B)
* bug and portability fixes

Changes to 0.4.4

* bugfixes, bugfixes, bugfixes
* very very very initial shlib plugin support

Changes to 0.4.3

* depreceated the bc way of adding functions
* better interactive parsing
* i18n actually works

Changes to 0.4.[12]

* new gnome frontend

Changes to 0.4 (includes all changes from all >0.3.1)

* new syntax for writing functions, more math like
* functions are now passed by value not by reference, this is unfortunately
  backwards incompatible but adds consistency and flexibility, so just instead
  of sum(4,5,&func) you'd write sum(4,5,func), with anonymous functions,
  the calling syntax does not change. inside the function then, one would use
  func(...) instead of *func(...)
* library file is compiled now for quick startup
* many new functions
* more matrix support
* complete complex number support with new operators

Changes to 0.3 (includes all changes from all >0.2.1)

* matrix support
* a couple of new operators (absolute value, get element/row/column, transpose)
* whole bunch of new functions

Changes to 0.2

* no more postfix, no more prefix, everything is infix
* conditionals are better
* variable/function references
* anonymous functions
