# Magma V2.26-8 Patch Notes

## Algebraic Function Fields

- A crash in `NormEquation` for function fields has been fixed. Reported by P. Koprowski who also suggested a fix.

## Algebraic Geometry

- A bad slowdown in `JacobianMatrix` (arising out the function `IsSingular`) for certain types of schemes has been fixed. Reported by J. Jahnel.

## Algebras

- A blowup in time caused in the construction of many algebras with involution has been fixed.  Reported by E. O’Brien.

## Arithmetic Geometry

- A bug in the Tuitman algorithm for computing zeta functions has been fixed, together with an improvement for certain types of inputs.

## Group Theory

- A bug in the normal closure operator for pc-groups has been fixed (it was possible for the operator to return a proper subgroup of the normal closure).  Bug reported by D. Roe as an incorrect `Kernel` of a character.

## Representation Theory

- A bug has been fixed in `IrreducibleModules(G, RationalField())` for a PC group $G$, where isomorphic modules were returned.
