Mistral Vibe

[2.24.0] - 2026-08-05

Added

• Admin config layer for shared/enforced config that applies over user config
• "Default" (unpinned) model option in /model and /config to track the recommended model without pinning a specific alias
• Server-side default model routing via experiment, never overriding explicit pins
• LLM retries surfaced in ACP/VS Code conversations via _session/retrying notification
• Explore subagent can load skills
• Local sessions start in the selected worktree
• User and project config layers compose; trusted project config overlays user config instead of replacing it
• Startup duration telemetry (vibe.startup)

Changed

• Experiment variants routed through the config schema; TOML/env/overrides now take precedence over GrowthBook assignments
• Autocopy: keyboard copy shortcuts give feedback, double/triple-click drag improved, and autocopy_to_clipboard documented

Fixed

• Drag-and-drop of files into the terminal when unfocused (iTerm2, Ghostty)
• Subagent session handoff after compaction
• Stale devstral-small thinking setting migrated to off
• Noisy non-Vibe events dropped from Sentry

Added

• /retry command to retry an interrupted response
• /rewind now lets you choose between forking and rewinding in place
• LLM retries surfaced in the UI and logs
• Read the config catalogue without an attached session

Changed

• /status shows provider prompt-cache usage and discounts cached tokens from the session cost
• Native copy hint on the clipboard notice

Fixed

• Refused config change no longer wipes the picker
• Git fsmonitor hook disabled in project context
• Signed reasoning blocks preserved
• Tab hint colored in config edit modal
• UPX disabled in the PyInstaller specs
• List formatting preserved when copying a selection from the TUI
• Duplicate approval widget prevented when callbacks overlap
• ACP usage update sent on session resume, fork, and new
• Context token display updated on session resume
• More frequent context window updates in ACP

Removed

• Unreachable chat mode

Added

• Skill-creator built-in skill: a guided flow to author, update, and delete your own skills
• Browser sign-in can target a custom login domain for self-hosted or private-gateway deployments
• Session stats now track provider cache-hit (cached) tokens

Changed

• Redesigned /config as a searchable, full-screen settings browser with typed edit modals and per-layer origin display
• App-server protocol extended and packaged as a standalone vibe-app-server binary for desktop integration

Fixed

• Cached-token counts now reported in session stats instead of always zero
• Zed ACP packaging preserves symlinks by shipping .tar.gz archives
• grep result chips open the correct file and no longer leak absolute host paths into context (ACP)
• ACP /rewind truncates in place instead of forking
• Extra fields in the whoami response no longer rejected
• ACP session history sorted by recency
• Blank permission prompt and duplicated user message in the ACP/VS Code webview
• WhoAmI result again tolerates extra fields

Added

• [A/B testing] OS-native managed shell tools
• vibe mcp add and vibe mcp remove commands to add and remove remote MCP servers without editing TOML
• Auto theme that follows terminal/OS appearance
• ACP project links surface for desktop integration
• Dense, grouped tool-call rendering in the TUI

Changed

• Trust dialog now defaults to "Trust folder" and is simplified
• Tool descriptions compressed to reduce context bloat
• Smoother, faster scrolling in long conversations
• Fixed unnecessary textual relayout computation on constant-size animation frames, removing lag spikes
• Major internal refactor introducing a JSON-RPC 2.0 app server as the single runtime owner between delivery surfaces (TUI, -p, ACP) and the core engine, replacing direct AgentLoop/callback coupling with a typed, projected protocol

Fixed

• Option+Left/Right word navigation in the chat input
• Unsigned thinking blocks dropped on backend replay
• SGR mouse protocol renegotiated when the emulator sends x10 bytes
• Crash on /resume delete confirmation
• Empty mapping treated as absent in CONCAT/UNION config merge
• LC_CTYPE used instead of LC_ALL in the bash tool environment

Added

• Registry skills content store and manifest for skill discovery
• Config schema exposed through ACP
• Checkpointer engine state model, owner union, and pending hunks

Changed

• [Breaking — hooks] Hooks graduated from experimental; hooks.toml is now stable. Every hook type is renamed: post_agent_turn → post_agent, before_tool → pre_tool, after_tool → post_tool (the hook_event_name payload field is renamed to match). Update existing hooks.toml files accordingly.
• @file mentions now inject as read_file tool calls
• Telemetry routed through client-side redaction
• Models field migration from list to dict
• VibeConfig cutover prep with persisted-config read and orchestrator SSL parity
• Reduced feedback survey frequency for users who already responded

Fixed

• Debounced the agent-switch spinner
• Neutral color for keyboard shortcut hints
• Falls back to the first available model when the active model is unknown
• HTTP requests now honor CIDR notation in NO_PROXY
