+# apt-ostree.py Changelog
+
+## [Unreleased]
+
+### Added
+- **Systemd Service Integration**: Complete systemd service setup for apt-ostree daemon
+  - Created `apt-ostreed.service` with proper security hardening and OSTree integration
+  - Added D-Bus activation service file `org.debian.aptostree1.service`
+  - Implemented comprehensive installation script with service file management
+  - Added proper directory creation and permissions setup
+  - Integrated D-Bus policy file installation with fallback creation
+
+### Changed
+- **Installation Script**: Enhanced `install.sh` to include complete systemd service setup
+  - Merged functionality from separate service installation script
+  - Added proper service file installation with fallback creation
+  - Updated service management commands to use correct service name (`apt-ostreed.service`)
+  - Enhanced documentation and usage examples
+
+### Security
+- **Service Security Hardening**: Implemented comprehensive security features
+  - `ProtectSystem=strict` for system protection
+  - `NoNewPrivileges=true` to prevent privilege escalation
+  - `ProtectHome=true` to prevent access to user directories
+  - `PrivateTmp=true` and `PrivateDevices=true` for isolation
+  - Restricted read/write paths to only necessary directories
+  - Root-only D-Bus policy for production security
+
+### Infrastructure
+- **Directory Structure**: Created proper directory hierarchy
+  - `/var/lib/apt-ostree` for daemon data
+  - `/var/cache/apt-ostree` for caching
+  - `/var/log/apt-ostree` for logging
+  - Proper permissions and ownership setup
+
+### Documentation
+- **Service Documentation**: Added comprehensive service management documentation
+  - Service installation and configuration instructions
+  - D-Bus testing and troubleshooting guides
+  - Usage examples for systemctl commands
+  - File installation locations and purposes
+
+## [0.1.0] - 2024-01-15
