## [2.15.0] - 2026-06-12

### Added

- **[Experimental]** `before_tool` and `after_tool` hooks: shell scripts declared in `hooks.toml` that fire around every tool call; hooks can deny the call, rewrite tool inputs, or append context to the output — enable with `enable_experimental_hooks = true`
- Message queue: messages typed while the agent or a `!bash` command is running are queued and shown above the input; Esc pauses the queue, Ctrl+C drops the last queued message (LIFO), Enter flushes the queue when paused
- Tool result output is now collapsed by default to keep responses scannable
- Common read-only shell commands (`ls`, `cat`, `pwd`, etc.) are allowed without approval by default
- Session deletion available directly from the resume picker

- Collapsed web tool output now shows the URL and search query at a glance
- `max_turns` support exposed over ACP via `set_config_option`

### Changed

- Compaction now re-injects prior user messages so the agent retains the original task goals across context resets
- **[Breaking — experimental hooks]** `post_agent_turn` retries no longer use exit code `2`; hooks must now exit `0` and return `{"decision": "deny", "reason": "..."}` on stdout to trigger a retry — exit code `2` is treated as a failure
- Model refusal stop reason is now surfaced to the user instead of stopping silently

### Fixed

- CLI UI no longer goes blank during app switches
- User messages are preserved correctly across repeated compactions
- Non-UTF-8 input is handled gracefully across all CLI surfaces

- Startup no longer crashes in unowned folders or when a git ancestor is unreadable

## [2.14.1] - 2026-06-08

### Added

- Startup prompt to install a pending Vibe update before continuing the session

### Fixed

- JetBrains IDEs no longer trigger a preemptive auth prompt over ACP and no longer drop terminal arguments

## [2.14.0] - 2026-06-04

### Added

- Image attachments via `@`-mentions in the TUI for vision-capable models
- Session deletion, exposed over ACP as the `session/delete` extension method
- Browser sign-in now shows a copyable fallback URL when the browser does not open, so SSH and remote sessions can complete onboarding
- Toast notification when a `SKILL.md` file fails to parse instead of silently dropping the skill

- `write_file` is now create-only and refuses to overwrite existing files
- Bumped `agent-client-protocol` to 0.10.1

### Fixed

- LLM calls now retry on network errors and timeouts (connection, read, write, remote protocol, timeout)
- Approval modal now sizes itself so the bottom of long tool-call payloads stays visible above the options block
- Banner connector count and `/mcp` panel ordering now reflect which connectors are actually usable and the user's enable/disable choices
- `disabled_tools` from runtime is merged with the TOML configuration instead of replacing it, and is enforced inside `ToolManager.get()`
- `shift+backspace` and `shift+delete` now work in the chat input
- Crash in the ACP `todo` plan-update handler when the model's tool call failed validation

### Removed

- Recursive search for nested harness files

### Added

- `enable_system_trust_store` config flag to switch the shared SSL context to the OS trust store for corporate TLS / private CA setups
