Regarding the dictionaries, I just checked for the French - German dictionary anacreon mentioned:

1.) Copy the dictionary file to .kobo/dict -> reboot -> there's no entry in the drop-down menu for the dictionary look-up.

2.) Then add the dictionary to the KoboReader.sqlite database in the Dictionary table under a "wrong" name ("French - German") -> save the database -> reboot -> there's now a "French - German" entry in the drop-down menu -> choose this dictionary -> error: "You don't have a English dictionary installed."

3.) Now change the name in the Dictionary table of the database to the correct name ("Français - Deutsch") -> save -> reboot -> there's now a "Français - Deutsch" entry in the drop-down menu -> choose this dictionary -> no error, look-up works without a problem

Edit: jackie_w was a little faster. For me, the additional entries in the Dictionary table survived the update. However, with older firmwares you actually didn't have to add an entry in the database to get them to work.

Additional information: It's now possible to have en1, en2, en3 etc. as additional dictionaries if you add them to the "ExtraLocales=" line in Kobo eReader.conf. The two character limit seems to have vanished. This might be because now the firmware seems to no longer compare the two character ISO language codes but the actual strings of the name in the database table.
