First of all, beta 3 is likely to be released soon with most of current issues fixed. The beta will also contain new prison station in Alaska (to fix some problems with Mitchell).
Also, I intend to change forward gun setups - again. There will be 4 types of forward guns (Liberty Cruiser, Liberty Gunboat, Kusari and Rheinland gunboat), each of them being a gun of different level (7, 8, 9, 10). This should remove the problem of exchanging forward guns from one ship onto another. Surely, in theory fighters will be able to equip these cannons, but because of energy requirements they will be absolutely useless even for bombers.
This will also allow me to put those guns back for sale. Now, if you lose the cannon, you have to re-buy the ship to get it back.
And their energy usage will be back to normal.
What else? Well, different minor issues probably not worth mentioning... in general, the new version is quite stable and performs well serverside, which is not bad :)
Edit:
More changes.
Sabre power supply will be upgraded slightly (it was NOT downgraded before, but anyway);
Newly bought Titans and Werewolfs will have even better power supply than now - it was present in beta 2, but I forgot to mention it in readme. Only for newly bought ships, however, so you'll have to re-buy to feel the change.
Talon will get 6x10 slots, but on expense of maneuverability.
Transport molecular and positron shields will have same capacity as graviton.
