0.4.0 - 2026-05-31

Release Notes

Added

• Experimental: --ipc-bind and --ipc-pid-file options for --with-ipc mode, enabling editors and external tools to set a deterministic socket path and track the session PID without parsing arf ipc list. Startup fails if the PID file cannot be written, so the caller is guaranteed to own the session or receive an error (#207).

Changed

• Experimental/Breaking: arf headless --bind renamed to --ipc-bind, and --pid-file renamed to --ipc-pid-file, for consistency with the equivalent new options on --with-ipc (#207).

Fixed

• Tab completion no longer times out inside function call arguments (e.g. str(aaa_ + Tab). R's completer takes significantly longer when inside a function call because it also looks up argument names. The fix raises the completion timeout floor to 1000ms in that context (and for :: completions), giving sufficient headroom while retaining a safety boundary against hung completions (#204)
