Translating MUI2

Hello everybody,

I am a translator for serbian language. I am not sure is there anything new to translate for MUI2. Everything looks same for me, but release notes states:
"The format of Modern UI language files has been modified to better support external strings. Private language files should be converted (and submitted as a patch in the spirit of open source)."
Am I missing something, or there is no need for any new translation?

There's nothing new to translate for now. Only the format changed, not the strings themselves.
