Query: The InvariantRing package for Macaulay2   We describe a significant update to the existing InvariantRing package for
Macaulay2. In addition to expanding and improving the methods of the existing
package for actions of finite groups, the updated package adds functionality
for computing invariants of diagonal actions of tori and finite abelian groups
as well as invariants of arbitrary linearly reductive group actions. The
implementation of the package has been completely overhauled with the aim of
serving as a unified resource for invariant theory computations in Macaulay2.
