changes:
-Plotting uses cairo (and is antialised) by using updated GtkExtra
-Improvements to line plots including autoscaling the y axis by default
-PDF export
-Lots of of fixes and other minor improvements all over
changes:
* Allow changing variable names for all plotting functions
* Add SlopefieldTicks, VectorfieldTicks, LinePlotVariableNames, and
SurfacePlotVariableNames, parameters
* Add AskButtons interactive function
* Add RungeKuttaFull, EulersMethodFull functions
* CHANGE: spelling fix: AuxiliaryUnitMatrix doesn't have two l's
* Support for setting legend on LinePlotDrawLine with a "legend" parameter
* Allow comparisons (== and !=) with null, treating it as an empty matrix
* Uses GIO instead of GnomeVFS
* Allow slopefield solutions to leave plot window by a small fudge factor.

-documentation / translation updates
Changes to 1.0.7:
* SYNTAX: Added a possibility to exactly specify which variables are copied
into a function's extra dictionary when it is being returned.
E.g. "`(x) [x0] = (x-x0)" will copy x0 from the current context. This
is a lot more efficient than the current behaviour which tries to copy
everything referenced.
* SYNTAX: Add "local" variables by specifying "local x,y,z" or "local *" as
the first statement in a function. Local variables are not visible from
higher contexts (functions called within)
* CHANGE: all system parameters are now protected and cannot be redefined
using the "parameter" keyword
* Add UserVariables, UndefineAll, ProtectAll, and add Undefine as an alias to
undefine.
* Add trigonometric Fourier series related functions:
NumericalFourierSeriesFunction, NumericalFourierSineSeriesFunction,
NumericalFourierCosineSeriesFunction, FourierSeriesFunction,
NumericalFourierSeriesCoefficients, NumericalFourierSineSeriesCoefficients,
NumericalFourierCosineSeriesCoefficients, PeriodicExtension,
EvenPeriodicExtension, OddPeriodicExtension
* Fix changing floating point precision!
* Fix uninitialized variable in graphing (Matthias Drochner)
* Improve variable substitution for returned functions to be more efficient.
Slightly changes behaviour with respect to global functions and variables
used.
* Plot windows now not treated annoyingly as dialogs
* Fix compilation/decompilation of all function attributes.
* Parse/Evaluate with a syntax error at end of string no longer terminate
genius
* Updated Mersenne stuff for the newest data from mersenne.org and
fix MersennePrimeExponents
* Fix opening new files from the command line.
* Update the gel library to use the new language features.
* Various other minor fixes
* Translation updates (Philip Withnall, Jen Ockwell,
Rodrigo Luiz Marques Flores, Daniel Nylander, Mario BlæÖttermann, me)
* For some of the changes the author (Jiri) was partially supported by
NSF grant DMS 0900885 and the University of Illinois at Urbana-Champaign
changes:
* Add QuadraticFormula, CubicFormula, PolynomialRoots, CommutationMatrix,
ToeplitzMatrix, MakeVector, RiemannZeta, GammaFunction
* Add --exec option to execute an expression from the command line
* Add chapter to the documentation on plotting and other minor updates to
the docs
* Fix complex number handling in number of functions, particularly in
all functions that use gaussian elimination and related routines
* Translations updated a teeny bit
* Fix rational powers
