Changelog

Sourced from pyscipopt's changelog.

6.2.1 - 2026.05.16

Fixed

• Fixed AttributeError when comparing NumPy scalars (e.g. np.float64) or 0-dim NumPy arrays against Expr/Variable on NumPy 2.x (#1218)

6.2.0 - 2026.05.11

Added

• Added solveProbingLPWithPricing() and test
• Expr and GenExpr support NumPy unary functions (np.sin, np.cos, np.sqrt, np.exp, np.log, np.absolute, np.negative)
• Expr and GenExpr support NumPy binary functions (np.add, np.subtract, np.multiply, np.divide, np.true_divide, np.power, np.less_equal, np.greater_equal, np.equal)
• Added getBase() and setBase() methods to LP class for getting/setting basis status
• Added getMemUsed(), getMemTotal(), and getMemExternEstim() methods
• Added addMatrixConsDisjunction() for elementwise disjunctions over matrix constraint expressions (MatrixExprCons/ExprCons) (#1084)
• Added isReoptEnabled() and raising error if not enabled upon calling reoptSolve()
• SOS1/SOS2 constraints are now realease after addition similar to the other constraint types

Fixed

• Removed Py_INCREF/Py_DECREF on Model in catchEvent/dropEvent that caused memory leak for imbalanced usage
• Used getIndex() instead of ptr() for sorting nonlinear expression terms to avoid nondeterministic behavior
• Fixed stubtest failures with mypy 1.20 by marking dunder method parameters as positional-only
• Return MatrixGenExpr in buildGenExprObj instead of MatrixExpr
• Plugins now hold strong references to their Model instead of weakref.proxy, fixing ReferenceError during cleanup callbacks
• Made test_tree robust to SCIP solver improvements by asserting visited node depths instead of node count
• Lower macOS wheel MACOSX_DEPLOYMENT_TARGET to 11.0 and patch bundled SCIP/SoPlex/GCG and GCC runtime dylibs to match

Changed

• Return NotImplemented for Expr and GenExpr operators if they can't handle input types in the calculation
• Speed up constant * Expr via C-level API
• Speed up Term.__eq__ via the C-level API

Removed

• Removed outdated warning about Make build system incompatibility
• Removed Term.ptrtuple to optimize Term memory usage
