My Glo just updated from 3.19.5761 to 4.2.8432 when I did a wi-fi sync.

It all went smoothly, but completing the sync after the new firmware installed took a very long time, like 15 minutes or so, it said it was updating my library and downloading covers. Updating my library seems to have involved replacing all my carefully corrected metadata with the publisher's original faulty metadata for all the KePubs on my device. Grr.

One problem I've found so far is the text on the book details page has very narrow line spacing, and this causes the same problems that narrow line spacing causes in the KePub reader, i.e. the page breaking in the middle of a line. (see the bottom line in the attached screenshot.)

Edit: Hmm, all the new covers it downloaded are in colour. That must be why the sync took so long, it was replacing all the old greyscale covers with colour ones. How bizarre.

Edit2: All the new downloaded covers seem to be missing the large N3_FULL versions, they only have the medium N3_LIBRARY_FULL and small N3_LIBRARY_GRID versions.
