Reported by A. Brumer. ## Elliptic Curves over Rationals - The Cremona database of all elliptic curves of small conductor has been updated to conductor 499,999. Important: ten isogeny classes have been slightly renumbered so that the first curve in the class is the optimal one. The affected classes are: 235470bb, 235746u, 258482a, 265706a, 333270bu, 359282a, 369194a, 375410g, 377034t, and 389774b. ## Galois Groups - Larger degree Tschirnhaus transformations have been allowed in the computation of [`GaloisSubgroup`](../GlobalFields/GaloisGroupsAndAutomorphisms/galois.md#function-galoissubgroup-fldnum-grpperm). Reported by J. Jones. ## Group Theory - A bug in `LowIndexSubgroups` for pc-groups has been fixed. The bug may have caused subgroup classes to be missed when the index limit was >= 2^30. Bug reported by David Craven. - A crash in [`TransitiveGroupIdentification`](../FiniteGroups/DatabasesOfGroups/transgp-data.md#function-transitivegroupidentification-grpperm) for groups with degree 33 to 47 has been fixed. Bug reported by A-S Elsenhans. - A bug which caused errors in the maximal subgroups of U(14, 11) as constructed by the intrinsic [`ClassicalMaximals`](../FiniteGroups/AlmostSimpleGroups/properties-lie-groups.md#function-classicalmaximals-monstgelt-rngintelt-rngintelt) has been fixed by Derek Holt. - Various corrections to the maximal subgroups of the classical groups in dimensions 13, 14 and 15 as constructed by the intrinsic [`ClassicalMaximals`](../FiniteGroups/AlmostSimpleGroups/properties-lie-groups.md#function-classicalmaximals-monstgelt-rngintelt-rngintelt) have been made by Derek Holt. ## Hilbert Modular Forms - A crash with [`NewformsOfDegree1`](../ModularArithmeticGeometry/HilbertModularForms/eigenforms.md#function-newformsofdegree1-modfrmhil) has been fixed. ## Hyperelliptic Curves - A problem with heights on genus 2 curves, involving trying to compute the regular model (when it is not needed), has been fixed. Reported by Sz. Tengely. ## Hypergeometric Motives - A problem with [`AlphaBetaData`](../ArithmeticGeometry/HypergeometricMotives/Functionality.md#function-alphabetadata-hypgeomdata) has been fixed. Reported by E. Costa. ## Hypersurfaces - A bug with [`NormalFormOfHypersurfaceSingularity`](../AlgebraicGeometry/Schemes/sing-norm-form.md#function-normalformofhypersurfacesingularity-rngmpol) involving incompatible base rings being used internally has been fixed. Reported by F. Rodriguez Villegas. ## Incidence Geometry - The [`CorrelationGroup`](../Geometry/IncidenceGeometry/automorphisms.md#function-correlationgroup-incgeom) intrinsic applied to an incidence geometry was incorrectly returning the automorphism group instead. This has been fixed. Reported by D. Leemans. ## Polynomial Rings and Groebner Bases - Bugs in local polynomial rings with one variable have been fixed. Reported by G. Blanco. ## Quadratic Forms - A bug in the polar group function which caused `IsometryGroup` to crash has been fixed. Reported by A. Sutherland.
