Mostly improvements to the sidebar UI/UX in this release along with trying to streamline the apperance of many smaller items in the system. If you have any issues with the UI/UX please report them as tersely / simply as possible and preferrably a single issue at a time unless you believe they're specifically related to a bug; this style of reporting means that there's less chance of missing things that might need addressing due to swamping.
