## [1.5.1] - 2025-12-14

### Changed
- **BREAKING CHANGE - Modern Python Package Management**: For Debian 12+ (Bookworm/Trixie), HBMonv2 now uses a Python virtual environment instead of system-wide package installation
- HBMonv2 Python dependencies installed in isolated virtual environment at `/opt/HBMonv2/venv` for Debian 12+
- pip_install helper function now uses virtual environment for Debian 12+ (PEP 668 compliant)
- systemd service file automatically configured to use virtual environment Python interpreter for Debian 12+
- Added python3-venv to system dependencies for Debian 12+
- Enhanced pip_install helper function with comprehensive error handling and user feedback
- Added proper error checking after all pip package installations
- Improved error messages to help users diagnose installation failures
- Added directory verification before installing from requirements.txt
- Changed deprecated --force flag to --force-reinstall for attrs package installation

### Fixed
- **Resolved externally-managed-environment errors on Debian 12/13** by using virtual environments instead of --break-system-packages flag
- **Resolved package conflicts with system-installed cryptography** by isolating Python packages in virtual environment
- Silent pip installation failures now properly reported to users
- Missing requirements.txt file now handled gracefully with warning instead of silent failure
- pip installation errors now cause the installer to exit with proper error messages

### Technical Details
- Debian 10-11: Continues to use standard system-wide pip installation (backward compatible)
- Debian 12+: Uses modern virtual environment approach following PEP 668 standards
- Virtual environment is automatically activated during installation
- pip is upgraded within the virtual environment for latest features
