• highlight_group key in segment description (both in configuration and in
  function output) was renamed to highlight_groups (note the trailing s).

• $POWERLINE_COMMAND is now a single path to one executable. No arguments to
  the executable are allowed inside $POWERLINE_COMMAND. Overrides using
  argument to $POWERLINE_COMMAND are now deprecated.
• In place of overrides being part of $POWERLINE_COMMAND variable all shell
  and tmux bindings now support overrides from $POWERLINE_CONFIG_OVERRIDES and
  $POWERLINE_THEME_OVERRIDES environment variables.
• In place of config paths specified as a part of $POWERLINE_COMMAND variable
  paths are now taken from $POWERLINE_CONFIG_PATHS environment variable.
• $POWERLINE_CONFIG was replaced with $POWERLINE_CONFIG_OVERRIDES for
  zpython bindings when talking about overrides.
• $POWERLINE_THEME_CONFIG was renamed to $POWERLINE_THEME_OVERRIDES in

  bindings when talking about path to powerline-config executable.
• In Vim in place of g:powerline_theme_overrides__{theme_name} per-theme
  dictionaries g:powerline_theme_overrides dictionary should be used. Theme
  names in this case are top-level keys in the new dictionary.

  option, not via paths option.

    Note that these options are deprecated and shall be used for testing purposes
    only.

  powerline.segments.common.wthr.weather. List of available segments can be
  found in documentation, section Common segments.
• Segments powerline.segments.common.now_playing and
  powerline.segments.common.players.now_playing were removed. In place of them
  all players should be accessed via their own segments. List of segments is
  available in Media players.

• Fixed Command-T finder labels: now CommandT:: and Finder:: parts are
  removed because all finders were moved to CommandT::Finder module in place
  of just CommandT.

  a \uXXXX\uXXXX surrogate pair in JSON.

  repository statutes (e.g. "U": only modification is unknown files) from
  marking repository as dirty.
• Refactored powerline.segments.common.players module: deprecated
  now_playing segment, replacing it with segments with names identical to
  player names (e.g. powerline.segments.common.players.mpd). now_playing
  segment will continue to work until powerline-2.0 though.
• Fixed powerline.segments.tmux.attached_clients segment: it was not working
  at all due to missing argument in one function call.
• Fixed regular expression used to detect NERDTree buffers.
