Claude Code v2.1.248 27 Aug 2026

Nudge control op reports a pending upgrade

Under the hood

Useful2 Signal2

Elsewhere

Tools driving Claude Code over IPC can now tell a queued upgrade from an active restart.

nudge

What

The nudge control message now returns upgradePending alongside restarting, so a tool driving Claude Code over IPC can tell "restarting right now" apart from "an upgrade is queued". upgradePending did not exist in 2.1.247.

Details

The op now awaits a combined status object rather than only the restart flag.
Not gated; the field is always present in the reply.

Evidence

upgradePending

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