# Magma V2.11-8 Patch Notes

## Commutative Algebra

- Major improvements have been made to the Faugere F4 algorithm for computing Gröbner bases.
- HFE systems (for which the secret degree parameter is up to 128) can now be solved in a much quicker time, by specifying the HFE parameter to the Gröbner procedure or the `GroebnerBasis` function.

## Language

- A bug in the parsing code for extended types in intrinsics has been fixed.
- A bug which caused Magma to crash upon the restoration of many saved workspaces has been fixed.

## Rings and Fields

- `SplittingField` had problems dealing with trivial extensions. This has been fixed.
- Functionality involving `Norm`, `Trace` and [`RationalFunction`](../GlobalFields/AlgebraicFunctionFields/elements.md#function-rationalfunction-fldfungelt) of function field elements over specified coefficient rings and fields has been restored.
- A problem involving solution of linear equations over p-adic fields has been fixed.
- A problem involving number fields defined by non-monic/non-integral polynomials has been fixed.
- A problem involving norm equations with trivial right hand side has been fixed.
