Hi,
HikaMarket package include the latest version of each language file.
When we are trying to reduce the package size of HikaShop, we have enough space in HikaMarket to include such files without riching the 2MB limitation.
I do not use Transifex for HikaSerial or HikaMarket, my packager system include a localisation module which create the missing translations in the different language files.
It allows me to follow the the evolution and keep the same translation sorting in each files.
After that, if you want to create a new project in Transifex for HikaMarket, you are free to do it.
If it can make you the translation process easier, I will encourage you in this way but at this moment, it will be more complicated to us to provide the language files directly in our website, so we will just put links to transifex pages.
Regards,
