# tmux-ide 2.9.12

> Direct Rust terminal delivery for the native GUI, changed-row updates and stable resize input.

`2.9.12` and the separately distributed native alpha `0.1.8` move the GUI's live
terminal stream and input into Rust. The Node broker continues to provide
discovery, SSH setup and application metadata. Terminal cells and keystrokes no
longer pass through it.

## Native terminal updates

Rust retains unchanged rows and converts changed rows for painting. Cursor-only
updates reuse cell rows. Binary terminal and image delivery reduces intermediate
encoding work; compatible same-host connections can use bounded, expiring image
file leases. Older clients retain their supported delivery path.

Alternate-screen projections can defer normal-screen history. Their receipts are
separate from complete-state acknowledgements, and history-dependent interaction
waits for a complete snapshot.

## Input and resizing

Typing and paste remain queued during temporary screen recapture without losing
the terminal's lifetime identity. Actual owner replacement still rejects stale
input. Commands admitted while the GUI is backgrounded cannot revive after a
rapid refocus, including resize requests.

Divider movement uses a local preview and commits the exact canonical split
boundary on release, avoiding repeated terminal reflow while dragging. The native
app also improves initial pane selection and supports Cmd-clicking terminal links.

## Updating

Update both the CLI/daemon and the [native macOS app](/docs/native-alpha) to use
the complete change. They are separate distributions; updating the CLI alone does
not update the GUI. Existing tmux sessions are preserved.

Automated protocol, input and rendering checks do not establish physical GUI
latency or TUI parity. This release makes no measured speedup claim.
