A bug in the creation of sub- and quotient algebras for associative algebras has been fixed.

A bug in the construction of the cohomology module for a finite matrix group over the integers has been corrected.

Coercion in the cohomology module has been extended somewhat so as to allow a wider range of possible user inputs, e.g., for cocycles.

A bug which prevented integer factorization from utilizing the MPQS algorithm under Windows has been fixed. This should significantly speed up integer factorization in the Windows build.

A bug causing Kernel to crash with an internal error when applied to matrix algebra elements over relative number fields and over number fields defined by non-monic polynmials has been fixed.

IsUnramified(FldAlg) now has a correct description string.

A bug in the pSelmerGroup computation for number fields that occasionally made the pre-image function fail has been fixed.

pSelmerGroup is fixed (the inverse of the returned map did not always work properly) and has an optional parameter "Raw" which remains to be documented.

A bug in computations BinaryQuadraticForms involving non-fundamental discriminants has been fixed.

A bug in the Euclidean division of quadratic fields causing internal errors and the return of incorrect results on a random basis has has been fixed.

A bug in the parametrization of function fields with respect to a divisor has been fixed for those function fields for which it occurred (essentially rational function fields).

Bugs in Eisenstein and WeierstrassSeries have been fixed. Delta for complex elements has been corrected.

Several bugs which caused precision loss when manipulating polynomials over the locals have been fixed.
