I would like to ask, there are new strings (texts) in latest RC 1.7 firmwares. So, not everything is translated to other languages.
Might be good idea to have final version of ts files for translation 'update'. (When final version of 1.7 will be ready for release). Also final version of manual might be handy for translators, as it is often very hard to guess how to translate the particular text if the context is missing/not clear. Seeing menus and texts in manual might help.
