 * **[Campaign AI]** Player front line stances can now be automated. Improved stance selection for AI.
 * **[Campaign AI]** Reworked layout of hold, join, split, and ingress points. Should result in much shorter flight plans in general while still maintaining safe join/split/hold points.
 * **[Campaign AI]** Auto-planning mission range limits are now specified per-aircraft. On average this means that longer range missions will now be plannable. The limit only accounts for the direct distance to the target, not the path taken.
+* **[Campaign AI]** Aircraft will now only be automatically purchased or assigned at appropriate bases. Naval aircraft will default to only operating from carriers, Harriers will default to LHAs and shore bases, helicopters will operate from anywhere. This can be customized per-squadron.
 * **[Kneeboard]** Minimum required fuel estimates have been added to the kneeboard for aircraft with supporting data (currently only the Hornet).
 * **[New Game Wizard]** Can now customize the player's air wing before campaign start to disable or rename squadrons.
