A bug in primary decomposition (arising from PrimeComponents applied to a scheme) has been fixed. Reported by C. Rito.

A bug in TwoCoverDescentInternal was found and fixed by M Stoll. When the degree of the defining polynomial is odd and the leading coefficient is not a square, the image of the point at infinity on the curve in the Selmer set was computed wrongly.

A bug in the machinery for constructing the quotient of a curve was found and fixed by M Stoll. The bug could cause errors in the intrinsic SquareFreePart which in turn is used by the intrinsics CurveQuotient and IsHyperelliptic.

The comment attached to SetPrecision has been adjusted to clarify that it changes the DefaultPrecisions rather than the actual precisions of a ring or field and its coefficient rings. Reported by E. Costa.

An improvement recently made to Factorization of polynomials has been fixed. Reported by M. Stoll.
