Description

It seems like there was major refactoring of the .ix[] indexing in 0.13 that breaks backwards compatibility in some ways.

E.g. .ix[row][col_name] = x used to work but doesn't. Sometimes .ix[row, col_name] = x also doesn't work and I have to use .loc[row, col_name] = x instead although the docs state that .ix[] just falls back to either .loc or .iloc.

I'm changing most of my code but I guess I'm just wondering whether that was made explicit as I can't find it in the release notes or if unittests failed to catch it?
