The last version, which I mentioned in my earlier comment, is of course version 0.3.13 so changes from version 0.3 to version 0.3.14 are very significant.
FreeOrion v.0.3.14 has been released for Windows, statically-linked Linux, and Intel Mac OSX!
Major changes since the last version include: Progress on the 3D interactive combat system (not yet playable however), which can be tested during regular games by running "freeorion --test-3d-combat" or directly by running "freeorion --tech-demo". Transition from SCons to CMake. Resource meter growth is now +1 per turn instead of a much more complicated formula. The visibility system has also been completely reworked.
