squashfs-tools >= 4.1 adds support for various compression other than gz. Most notably, LZMA/XZ that allows much better compression ratios. So please stabilize.
Arch teams, please test and mark stable: =sys-fs/squashfs-tools-4.2 Target KEYWORDS="alpha amd64 arm hppa ia64 m68k ppc ppc64 s390 sh sparc x86"
amd64 ok

Stable for HPPA.
I have fixed bug #400939 mid stabilisation but the changes are optical only - a change from IUSE=lzma to IUSE=xz, just to properly name the type of compression.
