Finite Fields ¶

A problem with parameters for Coppersmith has been fixed. Reported by D. Hansen.

Geometry ¶

Two local solubility glitches in dimension 4 for IsotropicSubspace have been fixed. Reported by Michael Harrison. Also, dimension 3 of this function now simply calls the conic code.

Lattices ¶

A bug in the construction of sub-lattices of real lattices has been fixed. Reported by W. Kroworsch.

Matrices ¶

A bug in matrix multiplication over finite fields has been fixed. Reported by D. Holt.

Number Fields ¶

A problem with QuadraticClassGroupTwoPart (D=-28757364) was fixed. Reported by the maintainer. This also affected IsotropicSubspace.

Polynomial Rings ¶

Some problems with boolean polynomial rings have been fixed. The function BooleanPolynomial has been added. Reported by M. Grassl.
