Release notes for PG 2.2.2
The WeBWorKTeam is pleased to announce the release of PG 2.2.2. This release builds on PG 2.2.1, adding several bug fixes and low-impact feature enhancements.
- Fixed some problems with the
Formulaobjects. (The tolerances used in the diagnostics didn't always match the ones used in the actual testing, and the wrong values were sometimes displayed when a multi-variable function was displayed as a graph.)
- Use tolerance flags from the
Realobject itself, if available, before looking at the context.
- Fixed a problem where polynomials like
x+4xwould be accepted even in single-power mode. The initial
xwas not being identified as a single power of
- Ensure that
ImageGeneratorsettings are correctly included from
WeBWorK::Constantsin all cases.
- Security: Since problems can provide their own graders, problem authors could previously use call
PG_restricted_evalin a custom grader to gain access to the full WeBWorK environment. Graders are now evaluated in the PG safe compartment, preventing this.
- Fixed a spurrious warning in
imagesmode when a hint or solution contains math expressions.
FUNCTION_CMPnow preserves the correct answer exactly as typed rather than reconstructing it from the parsed version.
- Fixed a problem with derivatives of constant-valued Matrices, Vectors, and Points. They were incorrectly getting an extra level of nesting.
