Also, if you post bugs make sure to mention if you're using Windows or Mac from now on. And please try to keep all bug reports to our official tracking site here: https://getsatisfaction.com/ftlgame . It's much more likely that we'll be able to keep track of and properly fix bugs if they are submitted there. Thanks!
Features:
-Mac OS X Beta is LIVE on Steam. Requires an Intel Mac, version 10.5.8 or above
-New playable ship (Zoltan) and alternative layouts/skins for *every* playable ship (unlocked with Achievements described below)
-40+ Achievements along with Achievement UI (within the STATS screen)
-About half are "ship specific" achievements (3 per ship) that you must be using the ship in order to earn it.
-Complete 2 out of 3 of a ship's achievements and you will unlock an additional layout/skin for that ship.
-Achievements use our own UI for now, we hope to integrate with Steam but our current focus was to make sure they weren't only available to Steam users
-Note: Federation Cruiser only has 2 achievements currently. This is not a bug, we're just not done

-New Sector type - Zoltan Space
-The Federation Cruiser now has a unique system that works similarly to the boss artillery weapons. It's a static, auto-fire weapon that exists separately from your normal weapon system - but prevents you from getting Cloaking
-The Top Score UI will track best scores for each ship type and layout separately, as well as maintain an overall top 5 (within the STATS screen)
-Stat window will show your last run stats if you open it from within the Gameover/Victory window.
-5 Crew "Hall of Fame" added to the stats screen for outstanding previous crewmembers
-New track from Ben Prunty
-More information added to the system tooltips (describing any possible status effect)
-Stealth Ship Hull Armor augment replaced by a System Plating augment that absorbs System damage instead of Hull
Tuning:
(Editted to try to make this more clear what I'm saying, the formatting isn't working)
EASY difficulty changes to hopefully make it more similar to normal in terms of scrap scarcity, but maintain an easier difficulty level with further reduced enemies:
1. All enemies will be easier, especially sector 1.
2. Scrap bonus is reduced slightly
Boss "Energy Shield" changes to make it easier for all builds to defeat:
1. Ion weapons do double damage
2. Bombs will teleport just outside of the shield and damage it
3. Beams will damage it
4. Damage numbers will appear when damaging the super shield to make all of this more clear
-Pike Beam and Hull Beam power requirements are now 2 instead of 3
-Text Input in the hangar works more as you would expect (arrows move the carat, holding a key will repeat that key, numbers are valid, and numpad keys function)
-Provided an escape event for if you get caught with your entire crew on the enemy ship and your teleporter is broken
-Numpad will work for all number input
-Tooltips appear faster and function more like you'd expect (mouse movement won't immediately disable)
-Less ambiguous Engi race description
-"Victory" marker is properly displayed in the top score screen on ships that you've won with
Bugs:
-Crash in certain restart / new game situations fixed
-Crash Fix: Rare crash on some enemy ship escapes
-Fixed: Sector number on the score screen would be incorrect if you had saved and resumed the game.
-Fixed: Boarding drones could stack on room locations when disabled
-Rock Armor and System Plating will properly block beam weapons
-Battle Drones will no longer paralyzed with fear in situations with too many boarders.
-Fixed: Super Shield would not draw properly if shield system was damaged/destroyed
EDIT: Forgot to do more than just list things:
