Reported by Mike Zieve. - The infinite places of degrees greater than the relative degree of a function field are now returned by `Places` when the degree argument is given as a second argument. Reported by Maarten Derickx. ## Galois Groups - Consistent setup has been ensured even for linear polynomials. Reported by Shiva Chidambaram. ## Integer Ring - Hangs in [`MPQS`](../BasicRings/Integers/factor.md#function-rngint-mpqs) have been fixed for very small inputs or for when the input has small non-squarefree factors. - A crash in multiplication of very large integers has been fixed. Reported by N. Katz. ## Lattices - A bug in `AdjacencyMatrix` has been fixed. - The `Dual` of an indefinite lattice can now be computed. ## Polynomial Rings - A hang in the `Roots` function when refining real roots of a certain integral polynomial has been fixed. Reported by Drew Sutherland. - A hang in factorization of a certain type of integral univariate polynomial has been fixed. Reported by Drew Sutherland. ## Representation Theory - A crash in `IrreducibleModules(G, K)` for cyclotomic field $K$ has been fixed. Reported by Peter Mueller. ## Sparse Matrices - A crash in sparse matrix elimination for very large sparse matrices defined over the integer ring (Standard version only) has been fixed. Reported by Daniel Bassett.
