Official releaseReleased Sep 3, 2026Original notes on GitHub

New features

Vim mode now supports undo with u and redo with Ctrl+R, preserving complete drafts including pasted content and attachments. ([#41941](https://github.com/openai/codex/pull/41941), [#42140](https://github.com/openai/codex/pull/42140))
The plugin CLI can list, install, and remove plugins from remote marketplaces. ([#42150](https://github.com/openai/codex/pull/42150))
Set tui.auto_recap = false to disable automatic recaps while keeping manual /recap available. ([#42101](https://github.com/openai/codex/pull/42101))
TUI history shows complete patches, input sent to background terminals, and individual completed commands. ([#41893](https://github.com/openai/codex/pull/41893), [#42107](https://github.com/openai/codex/pull/42107))
Plus and Team users receive an earlier warning when less than half of their allowance remains in an approximately five-hour usage window. ([#42142](https://github.com/openai/codex/pull/42142))

TUI sessions reconnect after an external app-server connection drops, preserving drafts and transcripts while keeping uncertain or queued submissions paused for review. ([#41911](https://github.com/openai/codex/pull/41911), [#41916](https://github.com/openai/codex/pull/41916), [#41918](https://github.com/openai/codex/pull/41918))
Full Access skips Guardian reviews for confirmation-only actions. User approval mode skips background Guardian scoring and prewarming, while sensitive-action checks and requests for user input retain their existing handling. ([#42147](https://github.com/openai/codex/pull/42147), [#42256](https://github.com/openai/codex/pull/42256))
Guardian review history survives compaction, restarts, and user-created forks while respecting rollback boundaries and isolating subagent history. ([#41879](https://github.com/openai/codex/pull/41879), [#42065](https://github.com/openai/codex/pull/42065))
Remembered MCP tool approvals are scoped to the selected app account, and relative MCP executable paths start more reliably on macOS. ([#42133](https://github.com/openai/codex/pull/42133), [#42117](https://github.com/openai/codex/pull/42117))
Rollout compression includes shared histories, codex exec resume handles compressed rollouts when selecting by working directory, and thread forks work with symlinked session roots. ([#42039](https://github.com/openai/codex/pull/42039), [#42135](https://github.com/openai/codex/pull/42135))

App-server thread metadata includes nullable model and reasoningEffort fields. Structured asynchronous questions are supported through request_user_input_async when enabled by the model catalog. ([#42151](https://github.com/openai/codex/pull/42151), [#42178](https://github.com/openai/codex/pull/42178))
tui.disable_paste_burst replaces the top-level setting, which remains supported as a fallback. ([#41976](https://github.com/openai/codex/pull/41976))
Adds the disabled-by-default features.context_management.experimental_mode configuration. When enabled for eligible ChatGPT Plus, Pro, or Pro Lite sessions using the Codex backend, it activates token-budget context, history notes, and the new_context tool. API-key sessions, custom providers, and temporary structured threads remain excluded. ([#42385](https://github.com/openai/codex/pull/42385))
