tmux-ide 2.9.7

2.9.7 fixes terminal connections to stock tmux 3.8, carries images from tmux panes to the native alpha, and makes upgrades move a running daemon onto the new release.

Stock tmux compatibility

Stock tmux 3.8 accepts capture-pane -R but returns a textual grid format rather than the JSON extension used by bundled tmux. The daemon now recognizes that format and uses its existing stock capture path. Previously this could close terminal streams with code 1011 and leave clients repeatedly reconnecting.

You do not need to downgrade tmux, change your PATH or kill existing sessions. The daemon also observes retirement after a concurrent shutdown transport failure.

Input after a viewer disconnects

A viewer that disconnected, or whose controller handoff was refused, could keep input authority for a session. Every other viewer then waited for input indefinitely. A viewer that asks for input now reclaims control from a holder whose connection is gone. Connected viewers still hand off normally, so only one client types at a time.

Upgrades move the running daemon

Rerunning the installer, or tmux-ide update on an installer-managed copy, now restarts a running older daemon on the new release. On macOS it also repoints a launchd job that still starts an older tmux-ide copy, such as a global npm install, at the managed launcher, keeping a backup of the job definition. Before, that job's automatic restart could keep bringing back the old daemon. Jobs that start a newer copy are left unchanged. tmux sessions keep running throughout. Pass --no-daemon-upgrade (or set TMUX_IDE_NO_DAEMON_UPGRADE=1) to keep the running daemon and update it later yourself.

When another tmux-ide comes first on your PATH, the installer now names its version and, for a global npm install, prints the exact command that removes it.

Updating

Update the CLI through your existing installation method:

curl -fsSL https://tmux-ide.com/install.sh | sh

Global npm installs refresh a running daemon during installation. For any other installation method, update the running daemon explicitly:

tmux-ide update --daemon --json

Existing tmux sessions are preserved. Apple Silicon macOS and glibc Linux x64/ARM64 remain supported; Intel macOS remains unsupported.

Separate native alpha

The native macOS alpha has a separate update path. Its pane-split recovery change refreshes the selected pane after layout changes without replaying input or split commands. Updating the CLI alone does not update the native app.

With a 2.9.7 daemon, the native window also shows images that programs in tmux panes send with the kitty graphics protocol, locally and over SSH. Unicode placeholder images are supported; cursor-placed images are best effort. The bundled tmux answers programs' graphics support queries; with a stock tmux, programs that wait for that answer may not send images. Set TMUX_IDE_KITTY_GRAPHICS=0 for the daemon to turn this off. The terminal app does not show images.
