# Magma V2.22-2 Patch Notes

## Algebraic Function Fields

- An error now occurs instead of a crash when a non-order, constructed through incorrect setting of a parameter, is used.

## Algebraic Number Fields

- An error now occurs instead of a crash when a non-order, constructed through incorrect setting of a parameter, is used.
- A bug has been fixed in `MaximalOrder` when the input number field has a non-monic or non-integral polynomial and the `Ramification` parameter is set.

## Groebner Basis

- An error when computing truncated-degree Groebner basis over a finite field of size $2^k$ ($k>1$) has been fixed.  Reported by G. Langeloh.
- A crash in `Multiplicity` for null sequences has been fixed. Reported by L. Los.

## Group Algebras

- An error now occurs instead of a crash when attempting to construct a group algebra over an infinite matrix group.

## Matrices

- A crash involving matrices over medium-size prime finite fields has been fixed.  Reported by J. Rouse.

## Modules

- A hang in computing an endomorphism ring of a general A-module in characteristic zero (the result of a maximal order computation) has been fixed.  Reported by N. Bruin.
