# Magma V2.25-8 Patch Notes

## Aggregates

- Iteration through associative arrays now works; previously, due to an oversight, only dual iteration was supported. Reported by M. Rodgers.

## Algebraic Number Fields

- Further improvements have been made to `MaximalOrder` computations using the Round2 algorithm and the `Discriminant` and `Ramification` parameters including fixes in the relative case.
- Improvements have been made to the computation of integer primes for use in the Montes algorithm to compute a `MaximalOrder`.
- Algorithm selection for computation of `MaximalOrder`s of number fields has been fixed in the cases where it was found to be broken.
- A few bugs related to the running of the Montes algorithm to compute `MaximalOrder`s and `Decomposition`s of primes have been fixed.
- The `LCM` of zero and another element of a quotient of an order has been fixed to return zero.
- A crash when applying the map returned by `IsIsomorphic` applied to a pair of number fields, where one is non-simple, has been fixed.

## Character Theory

- A crash in [`BrauerCharacterTable`](../RepresentationTheory/CharactersOfFiniteGroups/brauer-characters.md#function-brauercharactertable-chtr) when applied to a non-soluble group has been fixed.

## Coding Theory

- A crash in [`ConstantWords`](../CodingTheory/LinearCodes/structural.md#function-constantwords-code-rngintelt) over large non-prime finite fields has been fixed.  Reported by D. Wehlau.

## Commutative Algebra

- A bug in `Variety` for ideals defined over algebraic closures has been fixed.  Reported by F. Sauer.

## Elliptic Curves

- A bug in turning a singular plane quartic into an elliptic curve was fixed. Reported by E. Costa.
- A problem with [`ReducedTatePairing`](../ArithmeticGeometry/EllipticCurvesOverFiniteFields/pairings.md#function-reducedtatepairing-ptell-ptell-rngintelt) incorrectly using denominator elimination (giving wrong answers) has been fixed. Reported by A. Joux.

## Group Algebras

- The group argument is now allowed to be an infinite matrix group again.

## Groups

- A crash in `IsConjugate` for subgroups of a permutation group has been fixed.

## Hyperelliptic Curves

- A memory leak in `#` for hyperelliptic curves has been fixed. Reported by A. Brumer.

## Matrices

- `AddRow` and `AddColumn` now accept a `RngElt` as a scalar not only an integer. Reported by W. Bosma.

## Real Numbers

- `PowerRelation` now raises an error instead of crashing when the argument is infinite.  Reported by T. Dokchitser.

## Representation Theory

- An incorrect result for the function `IndecomposableSummands` (or `DirectSumDecomposition`) applied to a QG-module where G is a soluble group has been fixed.  Reported by J. Jones.

## Schemes

- The intrinsic [`RationalPointsByFibration`](../AlgebraicGeometry/Schemes/schemes-points.md#function-rationalpointsbyfibration-sch) now has a parameter `IncludeSingularPoints` that can be set to [`false`](../MagmaLanguage/StatementsAndExpressions/boolean.md#literal-literal-false-false) to ignore them.
- A precision problem in `IsLocallySolvable` has been fixed. Reported by J. van Langen.
- A problem with [`PointSearch`](../AlgebraicGeometry/Schemes/anfs.md#function-pointsearch-sch-fldrat-rngintelt) involving missing points (due to p-adic lift spaces not being sufficiently saturated) has been fixed. Reported by R. van Bommel.
