I would say it's BtS 3.19 since I haven't really added anything *special* to Extra since the last version (for 3.17). Unless it's the Terraforming modcomp, but I doubt that.

Announcement
When I'm done testing, I will upload the beta version of Extra 3.19b (full version). A long time ago an expanded future era was requested for the Extra mod. Now it's finally there. The reworked future era draws mainly on material from the
Next War,
Final Frontier and
Afterworld mods (although a few of units/buildings have been tweaked to make them fit better in the mod). The terraforming ability is a concept from
Call to Power, but I relied on Avain's modcomp to make it reality. I also added in some interesting concepts and buildings from the
FutureMod, such as the Antimatter Bomb and Antimatter Plant.
The core features of the 'old' future era in the Extra mod have been preserved, although a number of techs have been removed or renamed. The buildings School of Zealots, Stellar Market and Academy of Knowledge have been replaced with the Training Compound, Commercial Satelites and Particle Accelerator (with roughly the same effects). The Nutrition Facility and Mining Facility are now a whole lot more useful. Futhermore, there's a new late-game wonder: Mission to Mars.
Most important are probably the new future units, which are bound to make the future era a very interesting era for war. The ultimate naval units: the Alpha Battleship, Alpha Cruiser and Alpha Carrier are still present. What's new is that the cloning->bionics->cybernetics research path now extends to mutability, allowing for genetically engineered clones: Mutants, Supermutants and Sentinels. Another new feature is the inclusion of antigravity units: the Construct Ship, Invasion Ship, Defense Ship, Alpha Destroyer and Starbase, each with their own distinctive qualities. These units can fly over both land and sea, although they are not as fast as naval ships and they can't benefit from roads on land.
Since this is still a beta version, all these features are still subject to change (especially regarding the balance between the new units). The pedia strings aren't done either. Still a lot of work to be done.
