New description:
This bug tracks the current status of the toric varieties code and the
interdependence of new patches, which should be applied '''on top of Sage
4.6.2'''. Any (properly ordered) part of positively reviewed patches can
be merged at any time, there is no need to "bundle tickets."
'''Applied to the current Sage alpha/beta/rc'''
* #10233: Incomplete cython search path in setup.py
* #10522: Allow specifying coefficients of anticanonical hypersurfaces
* #10751: Upgrading 4.5.3 -> 4.6.2.alpha4 fails (fixes bug in #10233)
* #10675: Add nef complete intersections
* #10039: Make Parma Polyhedra Library a standard library
* #10809: Cartesian products of toric varieties
'''Positively reviewed:'''
* None at the moment.
These needs-review groups (separated by blank lines) can be applied
independently on top of the positively reviewed ones:
* #10943: Fan morphism fails on not full-dimensional fans
* #10882: Add kernel fan to fan morphism
* #11200: Add fibration check to `FanMorphism`
* #10529: dimension() and is_smooth() for algebraic subschemes of toric
varieties
* #10140: Base sage.geometry.cone on the Parma Polyhedra Library (PPL)
* #10023: Compute Hilbert basis of cone
* #10540: Spec and patches for singular affine toric varieties /
algebraic schemes. Depends additionally on #10529
