Oh sure, there’s some revamped scrollbars, Unity 7.3.2 that has some welcome bug fixes and Ubuntu’s version of the 4.2.1 Linux kernel, but this is no lycanthropic beast of great transformation as the name might suggest. You won’t find any major changes to Unity in this beta or, for that matter, the final release later this month.
Frankly, Ubuntu 14.04, a Long-Term Support release, had more changes than this.
