The next alpha release. => [[download:start|download]]

== application "matroid" ==

The application has now basic functionallity like computations between CIRCUITS, COCIRCUITS, and BASES of a matroid and constructing graphical matroids. 

== object PointConfiguration ==

The application "polytope" has a new object PointConfiguration that allows to deal also with non-convex point configurations. In particular, one can now deal with triangulations of point configurations without having to rely on TRIANGULATION_INT, and a visualization of point configurations and their triangulations is possible.

== Lattice Polytopes ==

Most methods in ''polymake'' dealing with lattice polytopes assume that the polytope is full-dimensional in the integer lattice. Two new methods transform a given lattice polytope into a full-dimensional lattice polytope either using the induced integer lattice or the lattice spanned by the vertices. 

There are several new constructions that return lattice polytopes: pyramids, bipyramids, transportation polytopes, and cayley polytopes. 

Lattice isomorphism for smooth polytopes can be checked.
