A crash when applying an isomorphism of number fields has been fixed. Reported by Sachi Hashimoto.
An incorrect result in PrimaryDecomposition for multivariate ideals in very small characteristic has been fixed. Reported by Yongyuan Huang.
A hang in the La Scala free resolution algorithm applied to a certain large graded module has been fixed. Reported by George Kirkup.
The IsIsomorphic function has been fixed to correctly handle degenerate cases of hyperelliptic curves (genus 0 and genus 1). Reported by Sachi Hashimoto.
An error has been fixed which would cause the incorrect decoding of the Magma-level printing for B.1 where B is a boolean polynomial ring with between 5 and 32 variables (inclusive).
The functions IsIsomorphic and IsMatrixRing are now supported for quaternion algebras defined over finite fields.
An IsIsomorphic function has been added to check whether two conic curves are isomorphic, and to return the corresponding isomorphism.
Grammar has been fixed for error messages when a string does not represent a number in a given base. Reported by David Roe.
