# Magma V2.11-4 Patch Notes

## Algebras

- The return types of `MatrixRepresentation` of a quaternion algebra or order have been fixed.

## Commutative Algebra

- A bug involving the reduced Gröbner basis when field polynomials are present has been fixed.

## Groups

- A bug in computing class matrices of permutation groups has been fixed. This bug may have caused character table computations to go wrong.

## Interpreter

- A small bug in package handling has been fixed.
- The `%h` specifier for printf now works properly.

## Rings and Fields

- A bug in `Integral` for power series over the p-adics has been fixed.
- A problem with `IsIsomorphic` for relative extensions over linear extensions of number fields that could cause an internal error has been fixed.
- The generator of degree 1 extensions of the p-adics now returns a root of the defining polynomial.
