+ Fix a bug that causes wrong analysis for sin[x] function + Fix a bug that causes random crashes when adding graphs with sin[] function

+ Fix a bug that cause equations such as y = (x^2 - 1)^(2/3) to report a wrong local maximum

+ Fixed a bug that causes tutorial to appear repeatedly

+ Added a tutorial on how to use some hidden functions + Added ability to lookup values + More flexible x:y axis ratio

+ Fix a major crash

+ Improved grid display on large devices + Fixed a crash happening randomly after entering equation + Introducing Quick Actions on iPhone 6S/6S Plus

+ Fix a bug that cause linear graphs such as y = -7x to disappear sometimes + Support for iPad Pro

+ Fix an issue that stops tracing state from being restored when app is restarted + Fix an issue that stops tracing to work sometimes when there are more than 1 graph + Fix an issue that prevents analysis of certain function classes, such as f(x) = sqrt(x^2 - 2) + Improve tracing UI + Add some missing translations

+ Rewritten UI. Support for iPhone 6 / 6 Plus / iPad multitasking + Rewritten math engine, with more optimized performance and more capabilities. Polar graphs are now supported. + Reworked keyboard, which now is adaptive and has more functions. + Reworked trace mode. Finding intersections are now easier. + Added Settings screen. + Added ability to save/print/share screenshot.

+ Fix crash on iOS 8

+ Fixed bug: cannot draw circles / ellipses when they don't cut one of the axes + Added support for quadratic hyporbolas + Improved special point label display - now points that collide due to zooming will be displayed together.

+ Fixed a bug that causes wrong special points to appear when a circle is added, and then changed to something else. + Fixed a bug that causes the whole app to hang when tracing near a vertical tangent + Added a setting to turn on/off keyboard sounds

+ Further UI changes + Added tracing support for y = f(x) and circles + Added more analysis for circles + Fixed an issue with equations such as y = cube_root(x^4). Thanks to one of our users for pointing this out!!

+ Added support for x = f(y), circles and graphs capable of transforming into y = f(x), x = f(y) or circles + Massive UI improvements + Improved Russian translation + Added French and Vietnamese translation
