Claude Code v2.1.221 3 Aug 2026

Interrupts now tear down non-durable artifact watch/live subscriptions

You'll notice

Useful2 Signal0

Artifacts

Interrupting a turn now shuts down leftover live artifact watch and edit subscriptions.

What

Interrupting a turn also cleans up live artifact wiring instead of leaving watch and live-edit subscriptions running.

Details

Applies to the interrupt control request and to the remote-cancel path.
After aborting the turn, live artifact wiring is cancelled with { durable: !1 }.
An interrupt carrying scope "turn-cancel" is exempt and leaves subscriptions in place.

Evidence

{ scope: "turn-cancel" }

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