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.\n\n**Why**\n\nNothing changes in how Claude Code behaves from this release.\n\n- Flag `tengu_ccr_replay_acks_at_request_dispatch`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.290; this account: on, anonymous baseline: on, compiled default: 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.\n- Area: Cloud Sessions\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
