- New *wm* command: `--restart`. It was already possible to restart `bspwm` without loosing the current state through `--{dump,load}-state`, but this command will also keep the existing subscribers intact.
- New settings: `automatic_scheme`, `removal_adjustment`. The automatic insertion mode now provides three ways of inserting a new node: `spiral`, `longest_side` (the default) and `alternate`. Those schemes are described in the README.
- New settings: `ignore_ewmh_struts`, `presel_feedback`, `{top,right,bottom,left}_monocle_padding`.
- New node descriptor: `smallest`.
- New desktop modifier: `active`.
## Changes
- The `focused` and `active` modifiers now mean the same thing across every object.
- Fullscreen windows are no longer sent to the `above` layer. Within the same layer, fullscreen windows are now above floating windows. If you want a floating window to be above a fullscreen window, you'll need to rely on layers.
- Monitors, desktops and nodes have unique IDs, `bspc query -{N,D,M}` returns IDs and events reference objects by ID instead of name.
-`bspc` fails verbosely and only returns a single non-zero exit code.
- The `DIR` descriptor is based on [right-window](https://github.com/ntrrgc/right-window).
- The `CYCLE_DIR` descriptor isn't limited to the current desktop/monitor anymore. (You can emulate the previous behavior by appending a `.local` modifier to the selector.)
-`bspc query -{N,D,M}` accepts an optional reference argument used by certain descriptors/modifiers.
- Monitors are ordered visually by default.
- The following settings: `border_width`, `window_gap` and `*_padding` behave as expected.
- External rules also receives the monitor, desktop and node selectors computed from the built-in rules stage as subsequent arguments.
- The `focus_follows_pointer` setting is implemented via enter notify events.
## Additions
- Nodes can be hidden/shown via the new `hidden` flag.
- Node receptacles can be inserted with `node -i`. An example is given in `git show e8aa679`.
- Non-tiled nodes can be moved/resized via `node -{v,z}`.
- The reference of a selector can be set via the `{NODE,DESKTOP,MONITOR}_SEL#` prefix, example: `bspc node 0x0080000c#south -c` will close the node at the south of `0x0080000c`.
- Node descriptors: `<node_id>`, `pointed`.
- Node modifiers: `hidden`, `descendant_of`, `ancestor_of`, `window`, `active`. Example: `bspc query -N 0x00400006 -n .descendant_of` returns the descendants of `0x00400006`.
All the commands that acted on leaves can now be applied on internal nodes (including focusing and preselection). Consequently, the *window* domain is now a *node* domain. Please note that some commands are applied to the leaves of the tree rooted at the selected node and not to the node itself.
## Changes
- All the commands that started with `window` now start with `node`.
-`-W|--windows`, `-w|--window`, `-w|--to-window` are now `-N|--nodes`, `-n|--node`, `-n|--to-node`.
- We now use cardinal directions: `west,south,north,east` instead of `left,down,up,right` (in fact the latter is just plain wrong: the `up,down` axis is perpendicular to the screen).
- The `WINDOW_SEL` becomes `NODE_SEL` and now contains a `PATH` specifier to select internal nodes.
- The `control` domain is renamed to `wm`.
-`restore -{T,H,S}` was unified into `wm -l|--load-state` and `query -{T,H,S}` into `wm -d|--dump-state`.
-`control --subscribe` becomes `subscribe`.
-`node --toggle` (previously `window --toggle`) is split into `node --state` and `node --flag`.
- The preselection direction (resp. ratio) is now set with `node --presel-dir|-p` (resp. `node --presel-ratio|-o`).
- The following desktop commands: `--rotate`, `--flip`, `--balance`, `--equalize`, `--circulate` are now node commands.
-`query -T ...` outputs JSON.
-`query -{M,D,N}`: the descriptor part of the selector is now optional (e.g.: `query -D -d .urgent`).
- Many new modifiers were added, some were renamed. The opposite of a modifier is now expressed with the `!` prefix (e.g.: `like` becomes `same_class`, `unlike` becomes `!same_class`, etc.).
- Modifiers can now be applied to any descriptor (e.g.: `query -N -n 0x80000d.floating`).
-`wm -l` (previously `restore -T`) will now destroy the existing tree and restore from scratch instead of relying on existing monitors and desktops.
-`subscribe` (previously `control --subscribe`) now accepts arguments and can receive numerous events from different domains (see the *EVENTS* section of the manual).
-`rule -a`: it is now possible to specify the class name *and* instance name (e.g.: `rule -a Foo:bar`).
-`presel_border_color` is now `presel_feedback_color`.
-`bspwm -v` yields an accurate version.
- The monitors are sorted, by default, according to the natural visual hierarchy.
