**Critical Fixes:**
1. **Fixed Error Hierarchy** (wikijs/exceptions.py)
- ConnectionError and TimeoutError now properly inherit from APIError
- Ensures consistent exception handling across the SDK
- Added proper __init__ methods with status_code=None
2. **Fixed test_connection Method** (wikijs/client.py)
- Changed from basic HTTP GET to proper GraphQL query validation
- Now uses query { site { title } } to validate API connectivity
- Provides better error messages for authentication failures
- Validates both connectivity AND API access
3. **Implemented JWT Token Refresh** (wikijs/auth/jwt.py)
- Added base_url parameter to JWTAuth class
- Implemented complete refresh() method with HTTP request to /api/auth/refresh
- Handles token, refresh token, and expiration updates
- Proper error handling for network failures and auth errors
**Bonus Fixes:**
- Dynamic user agent version (uses __version__ from version.py instead of hardcoded)
- Updated all JWT tests to include required base_url parameter
- Updated test mocks to match new GraphQL-based test_connection
**Test Results:**
- All 231 tests passing ✅
- Test coverage: 91.64% (target: 85%) ✅
- No test failures or errors
