Among the changes mentioned: the v3.5 update improved the scrolling animation in the web browser, sped up the sync process, and fixed a number of bugs. There's also a report that the long paragraph bug is fixed, and that this update adds support for the new cursed Adobe DRM. There is also one report that collections are no longer being displayed "in a weird order".
One beta tester also reports that Kobo improved the annotation features, including the changes made in the v3.4.1 firmware (some of which didn't work well). Other subtle changes include the state of the frontlight now being remembered across sleep, power off, and connection to PC (it used to default to off).
The firmware updates should be sent out automatically over the next few weeks, but if you don't want to wait then you can find download links and instructions over on MobileRead.
