Hot news of today is the Alpha 9 release of 0 A.D.:
Main additions are the Roman faction, a new combat concept and new trading system. The new combat concept allows for a strategic selection of your troops to counter certain units (spearmen are better against cavalry and so on) and the trading systems allows for setting up trade routes etc.
Oh and they are still looking for contributers ;)
A little bit less hot news, but still quite recent, is the new version 1.0.3.3. of Zero-K, a cool RTS set in the future (if you are a regular reader you should know it ;) ).
It now runs on the recently released 87.0 release of the SpringEngine and also features a new faction: the amphibious bots.
Sadly their interesting meta-game PlanetWars is currently closed for reworking, but the next round will happen at some point for sure.
