Compatibility
GeoGebra is backward compatible in sense that every file created with older version should open flawlessly in the current one. There are however several things which behave differently in 3.2 and 4.0:
- lists of angles, integrals, barcharts, histograms etc. are now visible
- lists {Segment[A,B], Segment[B,C] } are now draggable
- circle with given radius (e.g. Circle[(1,1),2]) draggable
- Distance[ Point, Segment ] gives distance to the Segment (was to the extrapolated line in 3.2)
- Angle[A,B,C] now resizes if B is too close to A or C
- Integral[function f,function g,a,b] is now transcribed to IntegralBetween[function f,function g,a,b].
- Objects that are a translation by a free vector are now draggable, eg Translate[A, Vector[(1,1)]]
- Points on paths may behave differently when the path is changed, e.g. point on conic.
LaTeX issues
The LaTeX rendering is now nicer, but some errors in LaTeX syntax which were ignored in 3.2 will cause missing texts in 4.0.
- Make sure that each
\left\{has corresponding\right.. - The array environment needs specification of columns (although it may be empty). Please use
$ \begin{array}{} a & b \\ c & d \\ \end{array}$for left aligned columns or$ \begin{array}{rr} a & b \\ c & d \\ \end{array}$for right-aligned ones. Old syntax$ \begin{array} a & b \\ c & d \\ \end{array}$won't work any more.
