Alpha patch release: thread section moves, richer client/thread messaging, TUI stack upgrades, and assorted model and protocol cleanup.
Changelog
[new] Threads can be moved between sections, with matching request/response support for section ordering and metadata updates.
[new] Client messaging events (Ack, ClientMessage, and chunked message events) for clearer multi-party / collaborative turn handling.
[new] Thread enrichment on the app server so loaded threads carry more complete context when listed or opened.
[new] MCP cloud configuration support in the CLI MCP command path.
[new]gpt-4.1 is available as a model identifier.
[changed] Several older or preview model IDs were dropped from the built-in set (gpt-4.1-mini, gpt-4.1-nano, gpt-5.1-codex-mini, gpt-5.4-nano, gpt-oss-120b).
[changed] Elicitation request handling was reworked around form and URL variants (including a legacy form path) for cleaner MCP-style prompts.
[changed] Sandbox policy deserialization now recognizes an external-sandbox mode alongside read-only behavior.
[changed] External-agent config migration in the TUI was reorganized into a dedicated module flow (same feature, clearer structure).
[removed] The exec JSONL event-processor path was removed in favor of the current output pipeline.
Under the hood
Exec-server relay work landed: Noise relay message framing and a dedicated codex.exec_server.relay protobuf path for structured relay traffic.
TUI runtime split out turn handling (turn_runtime) and added a small pets asset-pack module for optional UI flair.
Thread store gained local support for moving threads into sections; thread state tracks section order explicitly.
Dependency refresh: ratatui 0.30.x (with ratatui-core / ratatui-widgets), crossterm 0.29, ansi-to-tui 8, rmcp / rmcp-macros 3.0.0 stable, plus related compact_str / unicode-truncate bumps; layout solver moved from cassowary to kasuari.
Learn content endpoint https://learn.chatgpt.com is wired for in-product learning links.
Typed API surface expanded around threads (richer Thread payload, section-move params/responses, unsubscribe/list helpers) and tool/interrupt helpers; assorted stale payloads and notification shapes were trimmed.
