Got 1.4 yesterday - update went smooth as silk.
Things that are awesome:
Sync doesn't hose my current book place
Charge instructions displayed while charging
Can hide free books
Things that are not awesome:
The current book cover no longer displays in power-off state
I want to emphatically express that I am disappointed that the book cover is gone from the power-off screen. I loved that cover display - it set the Kobo well apart from the other ereaders and lent some great character. An option to choose if you want to display the cover in a future update would be great.
Keep up the excellent work guys
