Codex App 2026-03-18: Fork Conversations, Slash Commands
Codex app now lets you fork conversations from any message, adds mid-draft slash commands for model switching, and improves plan mode notifications.
TL;DR
- Fork conversations from any message, not just the latest one
- Slash commands now work mid-draft and control models/reasoning levels
- Plan mode notifications so you don't miss when Codex needs input
- Fixed thread handoff and subagent navigation bugs
New
- Fork from any message — Start a new conversation branch from earlier in a thread, not just the latest turn. Useful for exploring alternative paths without losing context.
- Mid-draft slash commands — Switch models and reasoning levels mid-prompt without restarting. Slash commands now work anywhere in your draft.
- Plan mode notifications — Get alerts when Codex is waiting for your input in plan mode, so you don't miss blocking questions.
Fixed
- Thread handoff and subagent navigation across worktrees and VS Code extension — resolves routing issues between environments.
- Performance improvements and stability fixes across the app.
Update via the Codex app or VS Code extension.
