SageManifolds deals with differentiable manifolds of arbitrary dimension.
In other words, various charts and frames can be introduced on the manifold and a given tensor field can have representations in each of them.
SageManifolds can also deal with generic affine connections, not necessarily Levi-Civita ones.
This release propagates further code changes related to the integration of SageManifolds into SageMath (cf.
As SageMath is, SageManifolds is a free and open source software based on the Python programming language.
