Excerpt from CHANGES file (https://sourceforge.net/p/tmux/tmux-code/ci/1.9/tree/CHANGES):

* 'default-path' has been removed. The new-window command accepts '-c' to
  cater for this. The previous value of "." can be replaced with: 'neww -c
  $PWD', the previous value of '' which meant current path of the pane can
  be specified as: 'neww -c "#{pane_current_path}"'
