# Magma V2.14-5 Patch Notes

## Arithmetic Geometry

- A bug in `Points` for Jacobians has been corrected.
- A bug in [`HasSquareSha`](../ArithmeticGeometry/HyperellipticCurves/jacobians-number-fields.md#function-hassquaresha-jachyp) for Jacobians (which could result in an incorrect rank bound) has been fixed.
- New functionality for genus one models, which had been inadvertently omitted, is now included.

## Galois Groups

- Two bugs in the Galois package independently found by N. Bruin and P. Mueller have been fixed. Both address problems in computations with certain non-monic polynomials.

## Group Theory

- The Atlas database `atlas.tar.gz` has been updated for 2.14. This new database must be used with the 2.14 executable.

## Groups

- A bug when the hom constructor for pc-group domain is not given enough arguments has been fixed. Bug reported by Kasper Andersen.

## Matrices

- The function `FrobeniusForm` for alternating matrices has been renamed to [`FrobeniusFormAlternating`](../MatricesLinearAlgebra/Matrices/canonical.md#function-frobeniusformalternating-algmatelt). `FrobeniusForm` is now a synonym for `RationalForm`.

## Module over Dedekind domains

- A bug in `Basis` has been discovered by S. Glasby. Instead of a (pseudo) basis, the first generators were returned.

## Polynomial Rings

- An inefficiency in multiplying large rational polynomials by scalars has been fixed. Reported by H. Hubrechts.
- A crash in `IsPrime` over fields of fractions has been fixed. Reported by K. Binder.

## Polynomials

- A bug in multivariate factorization over cyclotomic fields has been fixed. Reported by M. Grassl.

## Rings

- Expansions of elements of function fields at places can now be computed quicker than before.
