Codex 0.146.0

做專案做到一半，常會想另問一個題外問題，又怕把原本脈絡沖淡。現在可用 /new 或 /clear 替新工作階段命名，把重要執行緒釘在清單上，也能切到旁支對話後保留原對話。名稱、釘選與切換各做各的，原本的內容不必為了岔題收掉。它像桌上幾張貼著標籤的便條：急著處理的那張別壓到最底下，臨時寫的岔題也不用把主筆記塗得滿頁都是。下次回來時，還找得到原本做到哪裡。

你替團隊做了一個讓代理照固定流程做事的外掛，現在有更正式的包裝與發佈路徑。Codex 支援 Agent Plugins 的 manifest（描述外掛內容與用法的清單檔），可從工作區發佈，Amazon Bedrock 與 Claude Code 的額外外掛市集也能使用。這像替自己做的工具補上產品標籤、放上共同貨架；別人知道它是什麼，才能找到並安裝它。

同一段對話有兩種做法想比較時，不必倒帶或另開一段失去前情。現在可把執行緒 fork（分岔複本，從同一段前情各走各的）出去，連很長、分頁載入的歷史也能帶走；暫時分岔還可不出現在執行緒清單。清單只留你想長期看的分岔，短暫測試不會把首頁塞滿，也不必手動清掉。像小說家把同一章影印兩份，A 版讓主角往左走、B 版往右走，原稿依然留在桌上。

程式實際跑在遠端主機，畫面卻在你手邊時，現在 app-server 可透過 WebSocket（讓兩端持續互傳訊息的連線）接到遠端 Code Mode 主機。另一邊，支援相容介面的自訂模型供應商，也可單獨開啟 web search（網路搜尋）。像你坐在控制室，能一直和遠方工作台通話；換了供應商的模型，也不必因此失去查網頁的能力。

有人替你接上一個執行器，裡面附了可用技能與說明資源，現在 Codex 會發現它們，並安全讀取對應內容；你明確選取的技能也在範圍內。技能（把特定工作步驟與知識包成可呼叫說明）不是看到名字就直接亂用，而是先能讀到附帶資源，知道它提供哪些資料與操作邊界，再選合適的技能。這像借到一箱工具時先翻說明書與安全標籤，知道每件工具做什麼再動手。

公司網路要求經由 proxy（代理伺服器，代你轉送網路請求的中繼站）上網時，最怕只有登入能過、下載或遠端執行卻卡住。現在設定的代理會一路套到驗證、外掛下載、MCP 授權、遠端執行、WebSocket、重新導向和 LM Studio 連線。官方也補上共用 HTTP 用戶端、懂代理的連線池與安全對外請求的說明。它像門禁卡終於能開整棟大樓，不會只開正門。

剛改完登入或工具設定，卻得重開整個程式才能用，是很掃興的等待。現在 MCP（Model Context Protocol，讓 AI 連接外部工具的協定）連線與 Apps 工具會跟著驗證或設定變動更新；已關閉的伺服器會重新連線，健康的連線不用陪著重啟。變動只影響該更新的連線，不把其餘可用工具一起打斷。像調整家裡路由器後，斷線的房間自己接回網路，正在通話的房間則繼續說下去。

長回答剛送出就中斷，最難受的是不知道哪一段還留著。這版保留已提交訊息、最終回答、失敗回合的錯誤、匯入時間戳與核准設定，涵蓋中斷、重播、匯入和分岔。就算失敗，也留住錯誤紀錄，讓你知道當時卡在哪裡，重播時也不必猜測前一回合或重設核准選擇。它像剪輯影片時突然停電：已經放進時間軸的片段、標記的時間與權限選擇都還在，開機後不用憑記憶拼回去。

你在小筆電或分割視窗裡盯著終端機，最不想遇到按鍵沒反應、畫面擠壞或想中斷卻只能等。這版改善終端機回應與顯示：可不阻塞地中斷、鍵盤處理更穩、窄版面更能閱讀，超連結與提及結果也會刷新。等待回答時可以操作中斷，畫面資訊也持續保持可讀，提及結果也不會停在舊畫面。它像把狹窄駕駛艙的按鈕重新排好；需要煞車時按得到，儀表也不因空間小而看不清。

對話累積很長時，內容額度（context budget，模型一次能帶著看的內容空間）會吃緊，技能目錄可能得縮短。這版盡量保留更多可用技能，真的必須截斷時也會警告你。警告不是多餘通知，而是告訴你目前看到的目錄可能不完整。它像旅行箱快塞滿時，先努力把常用工具留在最上層；若有工具放不下，會直接告訴你缺了哪一區，而不是讓你以為整箱都帶齊。

安裝或更新工具時，背後不只是一個下載連結。發行檔、頻道資訊與安裝器別名現在可經 OpenAI 託管的發行基礎設施提供，GitHub 則當作備援；打包前也會替 macOS 的內附輔助執行檔簽署並公證。這些改動處理的是檔案交付與輔助程式驗證。像包裹優先走官方物流線，主線暫時不通才改走備用路；Mac 收到的零件還先有身分封條可驗。

企業裡的 Codex 更新不能只看有沒有新版，還要知道方案資格與誰能控制。這版加入企業方案辨識與應用內更新的管理員控制；同時 app-server 減少序列化負擔與建立請求時不必要的記憶體配置。前者把更新的決定權交給管理員，後者則減少處理請求時不必要的資料工作。它像寄貨前少做幾次重複打包，資料處理更省力；也像公司大樓的更新公告有管理室把關，知道哪些樓層適用、誰能決定何時換。

Mid-project, you may need to ask a side question without muddying the main thread. /new and /clear can name a new session, important threads can be pinned, and side conversations can be opened without closing the original one. Think of labeled notes on a desk: keep the urgent one visible and put the detour on its own sheet, so you can return to the work where you left it.

If your team built an add-on that guides an agent through a repeatable job, it now has a clearer way to be packaged and shared. Codex supports Agent Plugin manifests, workspace publishing, and extra plugin marketplaces for Amazon Bedrock and Claude Code. It is like putting a label on a tool you made and placing it on a shared shelf: people can identify it, find it, and install it.

When one conversation suggests two approaches, you no longer need to rewind or start over without its context. You can fork a thread, carrying even a long paginated history into each branch; a temporary fork can stay out of the thread list. It is like photocopying a chapter of a novel: send the character left in version A and right in version B while the original stays on the desk.

When code runs on a remote host while the interface is in front of you, app-server can now connect to a remote Code Mode host through WebSocket, a connection that keeps both ends exchanging messages. Compatible custom model providers can also enable standalone web search. It is like staying in a control room with an open line to a distant workbench; using another model provider need not take web search away.

An executor connected for you may come with skills and supporting resources. Codex can now discover those skills and safely read the associated material, including skills you explicitly selected. A skill is a reusable set of instructions and knowledge for a particular job; seeing its name is not enough. This is like opening the manuals and safety labels in a borrowed toolbox before picking up a tool.

On a company network that requires a proxy, it is frustrating when sign-in works but downloads or remote runs fail. Configured proxies now apply to authentication, plugin downloads, MCP authorization, remote execution, WebSockets, redirects, and LM Studio connections. Documentation also covers shared HTTP clients, proxy-aware connection pools, and safe outbound requests. It is like an access card that now opens the whole building rather than only the front door.

Changing a sign-in or tool setting and then restarting everything is an irritating pause. MCP connections and Apps tools now update when authentication or configuration changes. Closed servers reconnect, while healthy connections keep running. It is like adjusting a home router: rooms that lost the network reconnect themselves, and a room already on a call does not have to hang up.

When a long response is interrupted, the worst part is not knowing what survived. This release preserves submitted messages, final responses, failed-turn errors, imported timestamps, and approval settings through interruptions, replay, imports, and forks. It is like a power cut during video editing: clips already on the timeline, their time markers, and permission choices remain when you reopen the project.

In a small laptop window or split pane, you do not want unresponsive keys, a crushed layout, or an interrupt that makes you wait. Terminal responsiveness and rendering improve here: interrupts need not block, keyboard handling is steadier, narrow layouts read better, and hyperlinks and mention results refresh. It is like rearranging a cramped cockpit so the brake is reachable and the instruments remain legible.

As a conversation grows, its context budget — the space a model can carry forward at once — can become tight, and the skill catalog may need shortening. This release retains more available skills and warns when truncation is unavoidable. It is like a suitcase nearing capacity: keep the useful tools on top, and clearly say what could not fit instead of pretending the whole kit made the trip.

Installing or updating a tool is more than following one download link. Release artifacts, channel metadata, and installer aliases can now be served through OpenAI-hosted release infrastructure, with GitHub as fallback. Bundled macOS helper executables are also signed and notarized before packaging. It is like sending a parcel through an official delivery route first, then a backup route if needed, with a seal that lets a Mac verify the included part.

For Codex updates in an enterprise, it matters not only whether a release exists, but which plan qualifies and who controls it. This release adds enterprise-plan recognition and administrator controls for in-app updates. It also reduces app-server serialization overhead and unnecessary request-building allocations. One change is like avoiding repeated packing before a shipment; the other is like a building manager deciding which floors receive an update and when.
