Codex now preserves Guardian authorization across history compaction and moves the update_plan tool behind an opt-in flag, changing how users enable planning and how reviews persist.

Guardian authorization is now preserved across compaction and host-injected context, so model-visible rewrites no longer invalidate a valid review; the fix tracks a host-owned user-message revision separately from conversation history [1]. The update_plan tool is now opt-in: defaulting `tools.update_plan.enabled` to `false` means users must explicitly enable it, and the bundled guidance is stripped from prompts unless the tool is on [2]. MCP server names now support package-style syntax with `:`, `@`, `/`, and `.`, so names like `npm:@modelcontextprotocol/server-sequential.thinking` work across CLI and runtime, including OAuth lookup and config recovery hints [3]. The TUI now renders backend-owned rate-limit banners above the composer when they match the authenticated account, with actions for usage, credits, and resets, and refreshes usage after limit errors [4]. The MCP naming change was developed in parallel, reinforcing the shift toward package-style server references [5].
