# Magma V2.11-6 Patch Notes

## Algebraic Fields

- [`CoveringStructure`](../MagmaLanguage/StatementsAndExpressions/type.md#function-coveringstructure-str-str) for number fields of different types has been added.
- The degrees of places of relative fields has been fixed.

## Commutative Algebra

- The function `HilbertSeries` for ideals has been greatly sped up.

## Groups

- 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.

## Interpreter

- 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.

## Matrix Algebras

- The ambiguous `IsNilpotent` signature for matrix algebra elements has been removed.
