Comment (by egourgoulhon):
The new commit makes the ticket coincide with the algebraic part of
[http://sagemanifolds.obspm.fr/changelog.html SageManifolds 0.7], which
was released yesterday. The changes are very tiny with respect to commit
9684687; here is the log:
- src/sage/tensor/modules/comp.py:
`zero_element()` --> `zero()` (`zero_element()` being deprecated in
Sage)
- src/sage/tensor/modules/format_utilities.py:
improve documentation
- class `FormattedExpansion`:
- suppress the attribute "tensor" (it was actually useless)
- rename attribute "txt" to "_txt"
- rename attribute "latex" to "_latex"
- class `FiniteRankFreeModule`:
method `identity_map()`: add arguments "name" and "latex_name"
- class `FreeModuleHomset`: add method `one()` (for endomorphism sets)
- class `FreeModuleTensor`:
suppress methods `__radd__()` and `__rsub__()` : they were introduced to
write `0 + t`
and `0 - t`, where `t` is a tensor, before the coercion of 0 to a tensor
was implemented.
- src/doc/en/reference/tensor_free_modules/index.rst:add html target "..
_tensors-on-free-modules"
