v0.4.0

zfetch v0.4.0 — Linux Ecosystem Expansion

Fast. Lightweight. Rust-powered.

zfetch v0.4.0 expands Linux distribution and architecture support while preserving its fast, lightweight, and customizable system information CLI.

What's New

• Multi-distro packages: Native Debian/Ubuntu (.deb), RPM-based Linux (.rpm), and Arch Linux (.pkg.tar.zst) packages.

• Multi-architecture support: x86_64/amd64 and ARM64/aarch64 builds.

• Portable Linux binaries: GNU/Linux and statically linked musl builds.

• Improved compatibility: Debian builds targeting GLIBC 2.35 and Rocky Linux 9 RPM builds targeting GLIBC 2.34.

• Privacy Mode: --privacy redacts selected personal system information.

• Safe report export: --export supports text and JSON reports with private file permissions and overwrite protection.

• Enhanced hardware detection: Better CPU, GPU, ARM64, and desktop environment detection.

• Reliability: 80 passing Rust unit tests, CLI regression checks, and automated multi-platform packaging.

Verify Downloads

Download SHA256SUMS alongside your package and run:

sha256sum -c SHA256SUMS

All nine release packages passed SHA-256 verification. CI builds passed across the supported packaging targets; runtime compatibility may vary by distribution and system configuration.

Note: The interactive --update installer currently supports compatible Debian installations. For other formats, use the appropriate package manager or install manually.

• Display Layouts: Three modes available: compact, classic, and detailed.
• Built-in Themes: Six ANSI color themes with theme previews.
• Configuration Manager: Create and validate JSONC configurations directly from the CLI.
• Performance Optimizations: Optional hardware detection preserves lightweight default execution.
• Improved Reliability: 63 unit tests passed, plus automated CLI regression tests.
• CI/CD: Added GitHub Actions, benchmark tools, and Debian release validation.

v0.2.0

zfetch v0.2.0

Automatic Distro Logos and GitHub Update Manager

zfetch v0.2.0 introduces automatic Linux distribution logo detection and a GitHub-based update manager, making the lightweight Rust-powered system information tool easier to use and maintain.

This release also improves the built-in ASCII logo database while preserving custom logo support, JSONC configuration, and the existing native system detection features.

What's New

Automatic Linux Distribution Logos

• Automatically detects the Linux distribution using /etc/os-release.
• Displays a recognizable ASCII logo for supported distributions.
• Includes a compact, embedded ASCII logo database with support for Ubuntu, Debian, Linux Mint, Pop!_OS, Fedora, Arch Linux, and other distributions.
• Uses distribution family information as a fallback when an exact match is unavailable.
• Preserves custom ASCII logos configured through JSONC or --logo.
• Supports disabling the logo with --no-logo.

GitHub Update Manager

• Introduces zfetch --check-update to check the latest stable GitHub Release.
• Introduces zfetch --update for an interactive update workflow.
• Compares version numbers to determine whether an update is available.
• Recognizes development builds newer than the latest public release.
• Supports checksum verification for compatible Debian package updates.
• Keeps network operations separate from normal system information display.

Improvements

• Replaces placeholder distribution logos with recognizable ASCII artwork.
• Maintains support for custom ASCII logos and logo alignment.
• Improves update status messages and version comparison behavior.
• Preserves existing JSONC configuration and native hardware detection.
• Adds unit tests for logo selection and update management.
