Versions 2.09 - 2.11: Functions in Cartesian, cylindrical or spherical coordinates are now shown in proper mathematical layout.
Version 2.08: In conditional expressions, only one of the two alternatives is now computed, as is the case in the C and Java languages. Similarly, the second operand of a logical operator (&& or ||) is not evaluated if the first operator is sufficient to determine the result. For example, the condition x == 0 || 1/x ... can no longer cause a zero divide error.
