v1.29.2

GAMSPy 1.29.2 (2026-10-27)

New features

• #565: Add unicodeRepr to symbols, expressions, and operations to represent them in mathematical notation with Unicode characters, and Model.toUnicode to represent a whole model like Model.toLatex does.
• #923: Add an optional restrict argument to piecewise linear formulations and pwlinear to apply PWL relationships only to selected indexed entries.

Improvements in existing functionality

• #720: Problem, Sense, EquationType, VariableType, and FileFormat are now StrEnum subclasses, so their members compare equal to their string values.
• #945: Conv1d, Conv2d, MaxPool2d, MinPool2d and AvgPool2d window set creation improvements.

Bug fixes

• #938: Discard the statements of context managers such as gp.Loop, gp.For etc.
  that raised an exception instead of executing them later.
• #939: Stop changing the attributes of user given options object in place as it might affect the subsequent solves.
• #941: Stop leaving temporary autotemp symbols in the container when evaluating the records of an expression, operation, condition or implicit symbol fails.
• #944: Fix compilation errors for symbol and model descriptions that contain double quotes.
• #946: Fix attribute assignments that are ignoring literal indices and transposition.
• #947: Fix gp.math.trace modifying the domain of its input symbol.
• #948: Fix keeping the pre-freeze values of certain variables and equations after a frozen solve.
