 # Changelog
 
+## [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
+
