 #### Clients & Protocols
 
+- Remove `xdg-shell-unstable-v6` backwards compatibility
 - `XdgPositionerState` moved to `XdgPopupState` and added to `XdgRequest::NewPopup`
 - `PopupSurface::send_configure` now checks the protocol version and returns an `Result`
 - `KeyboardHandle::input` filter closure now receives a `KeysymHandle` instead of a `Keysym` and returns a `FilterResult`.
