I have updated from org-mode 8.2.10 to 8.3.1 and the behaviour of 

(org-do-promote), (org-do-demote), (org-promote-subtree), (org-demote-subtree)

has changed.  It now indents an unindented paragraph when demoting the headline.
e.g.
** subsection
There is a pre-defined list of commands, and you can add more such
commands using the variable org-speed-commands-user

This did not occur before and does not seem like desired behaviour.  I have checked this occurs in the testing build also.
