Verified facts

  • The /config command supports finding and changing settings; a follow-up message can immediately steer an ongoing turn.
  • Independent read-only tools can run in parallel; interrupting a turn also stops active Code Mode cells and nested calls.
  • Resuming restores permissions and network approvals while respecting current policy. The proxy checks permission before DNS and rejects duplicate Host headers.
  • The patched zsh shell is no longer bundled; old configurations receive a migration notice.

What changes

Proxy and resume changes directly affect authorization boundaries.

Practical implication

Test interruption, resume and network policy on a task without external side effects.

Availability

Belgium/EEA: the source specifies no explicit regional exclusion; availability depends on the account, plan and service region.

Limits and uncertainty

Account-eligible features, including Daybreak, do not become available to everyone merely by updating.
