 ## [Unreleased]
 
+## [1.3.6] - 2026-01-14
+
+### Fixed
+- **Non-interactive mode support** - Resolves Issue #76: Scanner fails with '/dev/tty: Device not configured'
+  - **`wp-check init`** - Now detects non-interactive mode and shows helpful error message
+    - Exits gracefully with instructions for CI/CD and AI assistant contexts
+    - Suggests using `install.sh` or manual configuration instead
+  - **`wp-check update`** - Now auto-updates in non-interactive mode
+    - Detects TTY availability using `[ -t 0 ] && [ -t 1 ]`
+    - Interactive mode: Prompts for confirmation before updating
+    - Non-interactive mode: Auto-updates without prompting
+  - **`install.sh`** - Now works in non-interactive mode
+    - Detects TTY availability at startup
+    - Interactive mode: Prompts for alias and tab completion preferences
+    - Non-interactive mode: Auto-configures with sensible defaults (adds alias and completion)
+  - **Impact:** Scanner now works correctly in CI/CD pipelines, AI assistant subprocesses, and non-interactive shells
+
+### Technical Details
+- **TTY Detection:** Uses `[ -t 0 ] && [ -t 1 ]` to check if stdin and stdout are terminals
+- **Graceful Degradation:** Commands that require interaction (init) fail with helpful error messages
+- **Auto-configuration:** Commands that can work non-interactively (update, install.sh) use sensible defaults
+- **Compatibility:** Works in GitHub Actions, GitLab CI, AI assistants (Claude, Cursor, etc.), and subprocess contexts
+
