This mostly has some bugfixes and tweaks, but new content is coming in Beta 3 just around the corner!

NEW STUFF:
- Sound slider in the options menu! About time.
- New achievement for researching all 'experimental' technologies

CHANGES:
- Missile guidance should be slightly improved now; they would lead their targets too aggressively and sometimes miss when fired at good angles while travelling at high speeds
- CORVETTE renamed DREDNAUT
- FLAK-BURST fire rate toned down a bit
- Reinforcement strength is now eased a bit more on earlier islands
- Aeros and weapons now have an explicit order to them, so they'll be more logically grouped in Loadout and Aerolab menus
- Ground turrets no longer contribute to the enemy's decision to send reinforcements (in effect this means you will have to destroy more unprotected targets to trigger them)
- Removed payload costs of some air-to-air missiles
- AGM-F turn speed and lock-on cone drastically increased
- AA-MR turn speed increased slightly

FIXES:
- Carriers give rewards again when destroyed
- Missile guidance versus moving ground targets vastly improved
- Co-op: only player 1 can set the carrier skin now. Player 1's skin isn't set when player 2 sets their skin.
- Co-op: dying now brings you back to the carrier menu, just like in singleplayer
- "Aero Superiority" achievement fixed so it doesn't require you to beat the game
