Robert Lougher — Fri, 02 Nov 2007 03:43:02 -0000

This is a new release of squashfs, a highly compressed read-only filesystem for Linux. Squashfs compresses both files, inodes and directories, and supports block sizes up to 1Mbytes for greater compression.

Squashfs 3.3 has some major improvements, block sizes have been increased to a maximum of 1Mbytes (default 128Kbytes), and sparse files are now supported. Both the Mksquashfs and Unsquashfs tools have been improved, and wildcard pattern matching is now supported in exclude/extract files. Many more improvements and bug fixes have also been made.

Squashfs 3.0 released

Robert Lougher — Thu, 16 Mar 2006 00:41:22 -0000

Squashfs 3.0 is a major improvement to Squashfs: filesystems and files are no longer restricted to 4 GB, hardlinks are supported, nlinks are supported, and "." and ".." are returned by readdir. A new Unsquashfs utility has been added which allows Squashfs filesystems to be decompressed without mounting.

Squashfs 2.1-r2 released

Robert Lougher — Wed, 15 Dec 2004 12:17:38 -0000

Squashfs2.1-r2 is a minor update to 2.1, which incorporates some code changes to allow it to be built using gcc < 3.0. This compability was broken in 2.1 because it used some gcc extensions only supported by 3.x. If you don't use gcc 2.x (and the majority of people don't), and you've already downloaded 2.1, then you don't need to upgrade to this release.

Squashfs 2.1 released

Squashfs 2.1 introduces indexed directories. Indexed directories considerably speed up directory lookup (ls, find etc.) for directories which are greater than 8K in size. All directories are now also sorted alphabetically which further speeds up directory lookup. Many smaller improvements have also been made.

Squashfs 2.0 released

Robert Lougher — Wed, 14 Jul 2004 14:12:07 -0000

Final release of Squashfs 2.0. This release adds some new mksquashfs options, adds initrd support for 2.6.x, and fixes a couple of bugs, most importantly bugs which prevented it working on amd64 systems. The 2.0 code is now considered stable. Squashfs is a highly compressed read-only filesystem for Linux. Squashfs compresses both files, inodes and directories, and supports block sizes up to 32K for greater compression. It is implemented as a kernel module under VFS.

A lot of changes to the Squashfs filesystem have been made under the bonnet (hood), to improve compression. Squashfs 2.0 has added the concept of fragment blocks and has increased the block size to 64K. This achieves a 5 - 20% compression saving, and allows Squashfs to achieve better compression than Cloop while retaining the I/O efficiency of a compressed filesystem.

In addition the maximum number of UIDs and GIDs has been increased to 256. This allows Squashfs to better support live CDs.
