Reported, with provided fix, by Y. Bo Ti and N. Bruin. ## Groebner Bases - A blowup in time/memory for Groebner basis computation in the case of sparse zero-dimensional ideals of high degree has been fixed. Reported by M. Zieve. ## Groups - A crash in the [`StandardCopy`](../FiniteGroups/AlmostSimpleGroups/related.md#function-standardcopy-monstgelt) intrinsic (group names 2A10 and 2A11) has been fixed. Bug reported by Stephen Humphries. - A bug where `IrreducibleModules` applied to a matrix group returned G-modules with G a permutation group has been fixed. Bug reported by Derek Holt. ## Integer Ring - The universe of the sequence returned by `Partitions` has been changed to be consistent with other sequences of sequences. Reported by M. Zieve. ## Lattices - A possible usage of uninitialized memory in [`BKZ`](../LatticesQuadraticForms/Lattices/reduction.md#function-bkz-mtrx-rngintelt) was removed. ## Linear Codes - A bug in the `AutomorphismGroup` and `IsEquivalent` functions for binary codes has been fixed. This bug may have caused equivalences and automorphisms to be not found. ## Matrices - Multiplication for small matrices over the rational field has been sped up. Issue reported by S. Elsenhans. - The computation of `CharacteristicPolynomial` over reals/complexes now goes via [`NumericalEigenvalues`](../MatricesLinearAlgebra/Matrices/numerical-linalg.md#function-numericaleigenvalues-mtrx-rngrecom). - A check has been added for `TensorProduct` when the result matrix would be too large.
