Internal ChangesSection of the release
What
The server setting tengu_ccr_replay_acks_at_request_dispatch, used for one kind of session, still falls back to off when the server sends nothing. Only internal naming changed. In a reading taken before this release, the server returned on for this site's account and for an account not signed in, which it first did on 2026-09-23.
Why
Nothing changes in how Claude Code behaves from this release.

Feature flag
tengu_ccr_replay_acks_at_request_dispatchOff by default, switched on for this account
The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.
This account: on · anonymous baseline: on · compiled default in v2.1.290: off
These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
