"I'm pleased to announce another release of Squashfs. This is the 22nd release in just over five years. Squashfs 3.3 has lots of nice improvements, both to the filesystem itself (bigger blocks and sparse files), but also to the Squashfs-tools Mksquashfs and Unsquashfs," stated Phillip Lougher about the latest release of the compressed read-only Linux filesystem. He noted that he still needed to fix filesystem endianness, then he was going to focus on getting Squashfs into the mainline kernel. New features found in this latest release include:
"1. Maximum block size has been increased to 1Mbyte, and the default block size has been increased to 128 Kbytes. This improves compression.
"2. Sparse files are now supported. Sparse files are files which have large areas of unallocated data commonly called holes. These files are now detected by Squashfs and stored more efficiently. This improves compression and read performance for sparse files."
