* New: split/pane support!
|

See [#157](https://github.com/wez/wezterm/issues/157) for
|
||||
overall status and additional information.
|
||||
* New: `window_background_opacity`, `window_background_image`
|
||||
and `window_background_tint` options to control using background
|

|
||||

|
||||
SHIFT modifier is removed from the set of active modifiers. This
