# tmux-ide 2.9.20

> The 2.9.19 changes, published: pane dividers on tmux servers started by an older tmux-ide.

`2.9.20` is a CLI/daemon release. It works with native macOS alpha `0.1.14`,
which needs no update.

It ships everything in [2.9.19](/docs/release-2-9-19), which was tagged but never
published to npm: pane dividers on a tmux server started by tmux-ide's own tmux
from before 2.9.6, and the matching `tmux-ide doctor` line.

The only other change is in the release process. A release check failed on
GitHub's new macOS runner image, whose OpenSSH prints its settings with
mixed-case names. The check now accepts that, and still compares every value
exactly.

Update the CLI/daemon with `tmux-ide update`. Existing tmux sessions are
preserved. Full list of changes:
