v0.4.0

Added

• Campaign co-op multiplayer - the host can pick a campaign mission in the lobby and play it with friends against the AI. Everyone shares the same battlefield: ground and sea units, mission objectives, tickets, time of day, and the pilot pool stay in sync for all players.
• Campaign briefings and dogfight death screens now use the game's own map menu - review the map, change your aircraft and loadout, and take off again from one screen.
• Joining a session while a match is running now shows a "game in progress" notice in the lobby, so you can wait for the host to return instead of being dropped into the middle of a match.

Changed

• Smoother movement for other players' aircraft and campaign vehicles, with noticeably lower network bandwidth during busy fights.
• Better performance in large battles - fewer stutters and less frame-time cost from bullets, explosions, and the scoreboard.
• More reliable respawning and spawn placement at airfields.
• Fairer scorekeeping: friendly fire no longer grants kill credit, and kill/death tracking is more reliable across respawns.
• Verbose logging and the deep performance profiler are now off by default; both can be re-enabled in the mod's config file.

Fixed

• Fixed the rearm/refuel screen going blank when a loadout contains missing or modded weapon data.
• Fixed campaign bases endlessly producing vehicles when their unit data is missing on your machine.
• Fixed a flood of errors and a stalling HUD when your radar or target selection still pointed at a unit that had already been destroyed in multiplayer.
• Many smaller multiplayer stability fixes across radar locks, kill confirmation, and returning to the lobby.
