# Magma V2.14-17 Patch Notes

## Diophantine Equations

- Fix an internal error in [`Solutions`](../GlobalFields/NumberFieldsAndOrders/equation.md#function-solutions-thue-rngintelt) of a Thue-equation. Reported by M. Bennet.
- A wrong bound (too small in certain cases) was used in [`UnitEquation`](../GlobalFields/NumberFieldsAndOrders/equation.md#function-unitequation-fldnumelt-fldnumelt-fldnumelt) resulting in internal errors.

## Elliptic Curves

- A crash in point multiplication has been fixed (and the computation sped up). Reported by D. Kern.

## Galois Groups

- Add support for trivial extensions in [`GaloisSplittingField`](../GlobalFields/AlgebraicFunctionFields/galois.md#function-galoissplittingfield-rngupolelt) which would fail on linear polynomials. Reported by T. Dokchitser.

## Matrix Groups

- A hang in matrix group order over fields of characteristic zero has been fixed. Reported by D. Yasaki.

## Modules

- In [`RowSpace`](../Algebras/MatrixAlgebras/homomorphism-element.md#function-rowspace-algmatelt) check for availability of echelon algorithm.

## Number Field Sieve

- Add better input checking to the NFS function to avoid internal errors further down. Reported by M. Grassl.

## Polynomial Rings

- `ExactQuotient` has been extended to handle more general rings in recursive definitions. Reported by M. Stoll.
- A crash in multiplication of very large polynomials has been fixed. Reported by D. Harvey.

## System

- Some problems with lock files for packages have been fixed. Reported by M. Stoll.

## p-adic Rings and Fields

- Use faster determinant algorithm.
- Improve precision estimates in `SplittingField`. Fixes a problem reported by T. Dokchitser.
