Anthropic's immutable Claude Code 2.1.302 release adds client-side auto-classifier model selection and an idle-compaction control, enables fork subagents by default across print, SDK, desktop and VS Code surfaces, caps concurrent prompt and agent hooks at 12, and fixes large-image, MCP, gateway, telemetry and cloud-routine failures.
Why it matters: Defaults now change delegation, concurrency and the model making some permission decisions. The release improves observability and recovery, but it can also alter cost, execution order and authority without an application-code change.
Anthropic's immutable Claude Code 2.1.301 release adds an unattended-retry cutoff, classifier verdict and category fields to tool-decision telemetry, a multiline mod input, and fixes that protect unpushed worktrees, recover model fallbacks, preserve workflow steps and distinguish tool-search or disk failures.
Why it matters: The release makes automatic permission decisions more observable while changing retry, fallback and cleanup behavior that can affect unattended work. The same telemetry can reveal sensitive decision context, so more visibility also creates a data-governance…
Claude Code 2.1.278 makes its server-side auto-mode classifier the default for Claude API and Enterprise users and for Bedrock, Vertex, Foundry and gateway sessions. Anthropic says server-side classification does not charge classifier overhead; affected gateway deployments can opt out, and the CLI now reports whether the server path is active.
Why it matters: Moving a permission classifier changes both billing and a control-path dependency. A proxy or gateway that cannot preserve the required request and response fields may fall back to the billed local path, so teams need evidence that the advertised mode is…
