## [1.5.0] - 2026-02-23

### Added
- **Network interface binding** — choose which NIC (IP) to use per server (VPN, multi-NIC setups)
  - Dropdown in server add/edit dialog (via `psutil.net_if_addrs()`)
  - `bind_interface` saved per server, used in SSH connect via `socket.bind()`
  - Works on Windows/macOS/Linux without admin rights
  - Status checker and terminal automatically use the bound interface
- `psutil` dependency in requirements.txt

### Fixed
- **"Install Everything" button** no longer hangs on error — try/except/finally ensures button always resets
- `generate_ssh_key()` handles missing paramiko gracefully (returns error message instead of crashing thread)
- `install_all()` catches per-step exceptions — all steps run even if one fails
- `_gen_key()` in Setup tab now catches and displays errors in the log

### Changed
- `check_connection()` refactored — uses shared `_connect_client()` instead of duplicated logic
- `_connect_client()` supports `bind_interface` with socket binding and proper socket recreation on auth retry
- Logging added to `install_ssh_script()`, `install_skill()`, `generate_ssh_key()`, `install_all()`
- `build.py` — added `--hidden-import psutil`
- `CLAUDE.md` — added version sync checklist
- `version.py` → 1.5.0

### Changed

  - One-click code copy to clipboard
  - Color-coded countdown (green → yellow → red)
  - Generate random secrets or paste existing ones
  - TOTP secret field in server add/edit dialog
- `core/totp.py` — TOTP module (pyotp, RFC 6238)
- `core/logger.py` — rotating file logger (5 MB, 3 backups)
- `pyotp` dependency in requirements.txt

### Changed
- **Encryption**: new stronger Fernet key with automatic migration from old key
- **Server store**: thread-safe file writes with locks, atomic saves (tmp + rename), auto-restore from backup on corruption
- **Status checker**: parallel server checks via ThreadPoolExecutor (up to 10 concurrent)
- **SSH client**: explicit channel cleanup in finally blocks, Unix key permissions (0o600)
- **Server dialog**: port range validation (1-65535), TOTP secret field
- `version.py` → 1.3.0

- Configurable config path (change servers.json location via GUI)
