Affine Algebras

·The common over-structure of the field F of fractions of an affine algebra A with A itself is now returned as F, so (A.1 in F) now works. Issue reported by Taylor Dupuy.

Algebraic Number Fields

·A crash when constructing polynomial rings over embedded algebraic number fields has been fixed.

Polynomial Rings

·A bug where HasRoot sometimes incorrectly returned false for polynomials over algebraic number fields has been fixed.

·A crash in RationalReconstruction when given incompatible polynomials has been fixed.
