CoveringStructure for number fields of different types has been added.
The degrees of places of relative fields has been fixed.
The function HilbertSeries for ideals has been greatly sped up.
Two classes of maximal subgroups of Alt(574) have been added. They are primitive, isomorphic to PSL(2,41), and do not extend to maximal subgroups of Sym(574). Bug reported by Colva Roney-Dougal.
The total time field in profiler output now reflects the time taken by the intrinsic as a percentage of total time. This is a more useful metric than with the previous behaviour.
The ambiguous IsNilpotent signature for matrix algebra elements has been removed.
