 * `XTGETTCAP`: added `query-os-name`, returning the OS foot is

+* `pad` option now supports 4-directional padding format:
+  `LEFTxTOPxRIGHTxBOTTOM` (e.g., `20x10x20x10`).
+* `--config=PATH` option is now automatically passed to new
+  terminals spawned via `spawn-terminal` action ([#2259][2259]).
+* Preliminary (untested) support for background blur via the new
+  `ext-background-effect-v1` protocol. Enable by setting
+  `colors-{dark,light}.blur=yes`. Foot needs to have been **built**
+  against `wayland-protocols >= 1.45`, and the compositor **must**
+  implement the `ext-background-effect-v1` protocol, **and** the
