Changes to 1.0.17 * Better precision for graphs especially when zoomed it a lot, and make font smaller if needed * Line plots and parametric plots now allow "fit dependent axis" automatically when y limits are unspecified. And this is the default in the UI * Add export of graphs to PDF directly * Line plot step size is adaptive, also line plots now detect jumps and do not draw a connecting line, try plotting UnitStep for example * Use arrow keys to move around a line plot * left-right arrow keys rotate surface plot * All plots are now antialiased on the screen (due to GtkExtra update and cairo usage). * Update internal GtkExtra to 3.0.5, and forward port all our changes/fixes (this gets us closer to supporting GTK+3 at some point) * Completion for "help on function" in the GUI * Fix FindRootBisection and FindRootMullersMethod * Factors is now a lot faster on very large numbers (as fast as Factorize) * Fix placement of labels on surface plots * A few small fixes and updates to the documentation * A few minor bugfixes * Update mersenne primes (new one is known) * Translation updates (Daniel Mustieles, Marek Černocký, Dimitris Spingos, Jiro Matsuzawa, Kjartan Maraas, Martin Srebotnjak, Matej Urbančič, Gil Forcada, Alexandre Franke, Joe Hansen, Miguel Rodríguez) * During making of these changes the author (Jiri) was partially supported by NSF grant DMS 0900885 and the University of Wisconsin-Madison
