Translate.erpnext.com how offten are updates are made?

Hi,

I’ve added and verified lot of translations for pl and I wonder when it will be merged or how can I implement these translations without “custom translation” or manualy changing the csv file in repository ?
I’ve seen reports that there should be an update/merge from time to time, but it looks like there hasn’t been any this year.

br,
Krzysztof
