A bug preventing norm equations in cyclotomic fields working has been fixed. The old version would return a User Error.
Some bugs in computing Groebner Bases for very large ideals have been fixed. Report by M. Grassl.
A missing check in MinimalPolynomial has been installed.
A missing check in RandomSchreier for matrix groups that made the order of GL trivial has been installed. Bug reported by Eamonn O'Brien.
A bug that caused crashes in MaximalSubgroups and Subgroups when applied to 3-dimensional unitary groups has been fixed. Bug reported by Markus Grassl & Peter Müller.
A bug that gave the message "bad data after rewriting" when dealing with finitely presented groups has been fixed.
A bug in CoprimeBasis that would result in the LCM of the sequence elements to change was fixed. Bug reported by W. Bosma.
Two errors relating to the construction of highest weight modules for Lie alegbras have been fixed.
A bug in IsIsomorphic that caused the function to wrongly return false for badly conditioned input (fields defined by polynomials with very large constant term) has been fixed.
A bug in the Galois package caused GalFactGroup to trigger internal errors on trivial input has been fixed.
A bug in the factorisation of ideals in number fields that in rare circumstances, depending on bad randomisation, would return wrong factorisation, has been fixed. This bug was reported by J. Quer.
InverseMod has been fixed to do automatic coercion on its arguments.
A bug in LCM and BiquadraticResidueSymbol for certain quadratic fields has been fixed. The old version would trigger internal errors.
A bug preventing norm equations in quadratic fields working has been fixed. The old version would return a User Error.
A problem in the handling of non-cyclic class groups of quadratic fields has been fixed. The old version would have issued an internal error in certain cases.
A problem with the conversion from quadratic forms in non-maximal orders to ideals has been fixed. The old version would return non-sensical and inconsistent ideals that would typically trigger internal errors.
A bug in jInvariant has been fixed. Bug reported by Jennifer Balakrishnan.
Crashes occuring after out-of-memory errors have been fixed.
