If you are not affected by any of the bugs fixed (see changelog), then not much. The main enhancement so far is the screen rotation support (but you may already have this installed independently anyway). There are also some more minor enhancements to busybox and PDF viewer which make life a bit easier, probably not the highest priority for most people but they were for me, so there ;-)

Going forward, what would you like to see included (keeping in mind that non-free components are out of scope for obvious reasons)?
