Ahoy!
Patch 1.5 and 'Flying the Jolly Roger' DLC are now availble in Russian only. English version is coming later this month. Sorry for the delay - we have already finished the translation itself, now all what is left is the final editing.
The patch will offer numerous improvements and fixes. And DX9 support.
