I just installed the subject firmware on my Kobo Aura ONE. I can't find any release notes, so I'm not sure what's changed. The only thing that I have noticed so far is that long presses are now required to change the format of the reading progress reported in the footer.
I've notice a couple of bugs I've been monitoring still haven't been fixed, but I'll leave that for the bug report thread.
I am hoping the helpful gentleman that usually advises whether "attempt to support newer firmware" may be used with new firmware releases will comment on the compatibility of this setting with this release
