A short release note for the October 20, 2012 version of the tensor document, kept with its support files. It lists new appendices (K, and J on deformation tensors), replaced and updated sections on continuum mechanics tensors, unit vector expansions, mixed-basis tensors, what a tensor is, and invariance of ds. It also notes small additions to Sections 6 and 7 and a cleanup in Section 8, and refers to an edit log.
