The next release will be 2.0.0 actually. If you want to see the translations in action, the easiest way is to build your own image and test it. The development environment is very dependable and well tested (either setup your own host or use our ready-made VM).
I wish there were an easier way to test these things but right now this is what I can offer.
Hey, there actually *is* a simpler way :-)
To test my polish translations, I simply download them onto my AskoziaPBX:
mount -n -o remount,rw /offload/
wget
http://www.viste-family.net/mateusz/Temp/AskoziaPBX-PL/messages.mo -O /offload/rootfs/usr/www/locale/pl_PL/LC_MESSAGES/messages.mo
Of course you can adapt this to use your own translations, without having to rebuild your own image ;-)
