## [1.0.1] - 2025-11-11

### Fixed
- **Critical**: Fixed block-level `failed_when` syntax errors in detect_hypervisor.yml
  - Moved `failed_when: false` from block level to individual tasks
  - Affected blocks: libvirt, Proxmox VE, LXD/LXC, Docker detection
  - Fix ensures proper error handling without Ansible syntax errors

- **Critical**: Fixed Jinja2 template conflicts with Go templates
  - Escaped Docker/Podman Go template syntax to prevent Ansible interpretation
  - Changed `{{.Field}}` to `{{ "{{" }}.Field{{ "}}" }}` in shell commands
  - Affected: Docker version, Docker images, Podman version detection

- **Critical**: Added missing OS-specific variable files
  - Created `vars/Debian.yml` for Debian/Ubuntu family
  - Created `vars/RedHat.yml` for RHEL/CentOS/Rocky/AlmaLinux family
  - Created `vars/Suse.yml` for SUSE/openSUSE family
  - Files define OS-specific package names and paths

### Security
- All shell commands use `changed_when: false` to prevent false change reporting
- No sensitive data exposed in task output

- Hypervisor detection and information gathering
  - KVM/libvirt support
  - Proxmox VE support
  - LXD/LXC container support
  - Docker container support
  - Podman container support
- Operating system information collection
- Network configuration details
- Disk and filesystem information with usage statistics
- System resource monitoring (CPU, memory, swap, uptime)
- Logged-in users tracking
- Top CPU and memory consuming processes
- JSON output generation for automation
- Human-readable summary display
- Tag-based selective execution support

### Features

#### Information Categories
- **System**: Hostname, OS, kernel, architecture, uptime
- **Hardware**: CPU model/cores, memory, storage devices
- **Network**: Interfaces, IP addresses, routing, DNS
- **Storage**: Disk usage, filesystem types, mount points, LVM
- **Virtualization**: Hypervisor type, VM/container details
- **Performance**: CPU load, memory usage, swap, top processes

#### Output Formats
- Structured JSON output to `stats/` directory
- Human-readable debug output to console
- Summary displays with categorized information
- Optional detailed hardware reports

#### Execution Tags
- `gather`: Run all information gathering tasks
- `hardware`: Hardware information only
- `network`: Network information only
- `storage`: Storage and filesystem information only
- `hypervisor`: Virtualization platform detection
- `performance`: System performance metrics
- `validate`: Health checks and validation

### Security
- Read-only operations (no system modifications)
- All commands use `changed_when: false`
- Sensitive data handling with appropriate permissions
- No credentials or secrets exposed

### Compatibility
- **Debian Family**: Debian 10+, Ubuntu 20.04+
- **RHEL Family**: RHEL 8+, CentOS 8+, Rocky Linux 8+, AlmaLinux 8+
