Incompatible changes:

  listed in 4e6b0a7ec8f2fa54053e4162c8b604a85e8d667d.
- `highlight_group` key in segment description (both in configuration and in 
  function output) was renamed to `highlight_groups` (note the trailing `s`).
- `attr` key in colorschemes was renamed to `attrs` key (note the trailing `s`).
- All highlight groups looking like `foo.bar` were renamed to `foo:bar`: dot in 
  highlight group names is no longer allowed.
- `detect` argument value was renamed to `auto` in network segments.
- `$POWERLINE_COMMAND` is now a single path to one executable. No arguments to 
  the executable are allowed inside `$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 
  zpython bindings.

  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.
- In IPython configuration paths list can be specified via `config_paths` 
  option, not via `paths` option.
- Some long options that defined overrides were renamed:
  - `--theme_option` was renamed to `--theme-override`.
  - `--config` was renamed to `--config-override`.
    Note that these options are deprecated and shall be used for testing purposes 
    only.
- All long options that used to have underscore in them are now using 
  HYPHEN-MINUS instead. I.e.
  - `--config_path` was renamed to `--config-path`.
  - `--last_pipe_status` was renamed to `--last-pipe-status`.
  - `--renderer_arg` was renamed to `--renderer-arg`.
  - `--theme_option` was renamed to `--theme-override`.
    Short options were not touched.
- All segments from `powerline.segments.common` were removed. Now they live in 
  `powerline.segments.common` submodules: e.g. 
  `powerline.segments.common.weather` is now 
  `powerline.segments.common.wthr.weather`. List of available segments can be 
  found in documentation, section [Common segments](http://powerline.readthedocs.org/en/master/configuration/segments/common.html).
- 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](http://powerline.readthedocs.org/en/master/configuration/segments/common.html#module-powerline.segments.common.players).

  U+10000 in UCS-2 Python builds are no longer considered non-printable.

  Python builds.

  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.
