Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Keepalive can now kill a silent socket, but nothing turns it on

Not switched on
Useful1 Signal3
Remote Control

Dead WebSocket connections could be killed after a silence deadline, but nothing sets one.

A keepalive deadline that terminates silent sockets exists but no connection configures it in this build.

What

The WebSocket monitor's keepalive gained a deadline: if no message arrives within it, the socket is terminated rather than pinged again. The only keepalive configuration in this build supplies opening frames, the ping frame and an interval, and no deadline, so no connection currently uses this.

Evidence

openFrames

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
