## Project history and usage

Squashfs-tools provides the user-space tools for creating, extracting, listing, and converting SquashFS compressed read-only filesystems.

### Project history

The Squashfs-tools changelog records an initial 1.0 release in 2002 and a 4.0 release in April 2009 with major filesystem improvements. The Linux kernel documentation describes SquashFS as a compressed read-only filesystem for Linux intended for archival use and constrained block-device or memory systems.

### Adoption history

The official kernel documentation says squashfs-tools is very likely packaged by Linux distributions, and the project README includes packaging-status material. The input package-manager facts list Homebrew and zypper for this formula.

### How it is used

The main commands are mksquashfs for building images and unsquashfs for extracting or listing them, with newer sqfstar and sqfscat commands supporting tar-style and cat-style workflows. Recent releases emphasize reproducible images, parallel reading, streaming output, and richer help/man-page coverage.

### Why package nerds care

Package nerds care because SquashFS images are common in live systems, appliance-style images, containers, firmware, and compressed software payloads. The tools are the boring but essential bridge between package contents and a compact read-only filesystem artifact.

### Timeline

- 2002: Squashfs-tools 1.0 initial release.
- 2006: 3.0 and 3.1 releases added major filesystem and tools improvements.
- 2009: 4.0 release introduced major filesystem improvements.
- 2023: 4.6 release improved xattrs, pseudo files, and conversion workflows.
- 2025: 4.7 release added parallel file reading and reproducible-image improvements.
- 2026: 4.7.5 bug-fix release published.
