Paradox Interactive has released Res Publica, a new expansion for Europa Universalis IV, the latest installment in their grand strategy series. They say the pack is available from the Europa Universalis IV website (we don't see it there as of this writing) and an update on Steam indicates it's available from there. Here's the pitch on the add-on, including today's Latin lesson:

Res Publica, a Latin phrase meaning “Public Affairs,” is the latest expansion to Europa Universalis IV, gives players even more ways to rewrite history in the award-winning grand strategy title, enhancing and improving the experience of governing with a close eye on history. In Res Publica, dictators and diplomats will discover new means of directing the growth of their kingdoms, and discover new tricks to keep their nation stable – or crumble their enemies’ support.
