    8 Introduction
    9 
   10    The [2]WeBWorKTeam is pleased to announce the release of PG 2.3.2.
   11    This version builds on PG 2.3.1, adding several bug fixes and
   12    low-impact feature enhancements. Changes include:
   13 
   14      * [3]MathObjects: Use Perl reals rather than [4]MathObjects reals
   15        for adaptive parameters in matrices.
   16      * [5]MathObjects: Add a new operator // to be the same as / except
   17        its TeX form is a/b rather than \frac{a}{b}. This makes it
   18        possible get horizontal fractions in exponents, for example, where
   19        vertical fractions often don't look so good.
   20      * [6]MathObjects: Fix a problem with the TeX representation used in
   21        previewing students' answers. (Specifically, a + b would be
   22        represented as a\quadb. Now it is represented as a \quad b.)
   23      * [7]MathObjects: Fix a problem with the custom list checker.
   24      * [8]MathObjects: Added a Vector2D context that has i and j defined
   25        as vectors in 2-space so that they can be used to generate vectors
   26        in 2D. This avoids students getting the "incorrect number of
   27        coordinates" error.
   28      * [9]MathObjects: Modified the way the Parser-based versions of the
   29        traditional answer checkers get copies of their contexts. They now
   30        use a new method getCopy to obtain the copy either from the
   31        problem's context table or the default table (rather than only
   32        from the default). That way the instructor can use
   33        parserCustomization.pl to customize the contexts used by the
   34        answer checkers.
   35      * [10]MathObjects: Clear the error message in Context before it is
   36        used in an answer checker (prevents bleeding of one error into a
   37        later answer).
