Features:
- Challenges: in addition to the 3-star system, you can now complete challenges for each level. These do not count towards unlocking weapons but do gain your troopers XP.
- Plan saving: all paths up to the first "Play" command are saved and restored when restarting the map, also called the Daimaju feature.
- Unlockable items: items are now unlocked using the Stars currency.
- Unlockable classes: trooper classes (assaulter/breacher/etc.) are now unlocked by leveling up your squad.
- 8 new firearms.
- 3 new armor types.
- 8 new maps.
- Many improvements to enemy AI.
- Line of sight preview when drawing a path.
- Proper feedback indicators for enemies that are about to execute a hostage + added countdown timers for executioners.

- When the line of fire is blocked by a friendly unit, a proper graphical indicator is rendered.
- The VIPs in "Protect the VIP" scenarios must be activated by proximity in order to be able to control them.
- Can customize the name/appearance of your troopers (wip, for now you can only loop through all the troopers in the database).
- Can now change resolution from the in-game video options.
- Support for more .wav formats. Previously an unknown format would crash the game.

Fixes:
- Fixed the 50 mods limit downloaded from Steam.
- The "Export replay to movie" feature now works correctly on more (all?) hardware configurations (and faster).
- A crash that would sometimes happen after enabling/disabling mods and playing a game.
- Mods are no longer deleted after starting the game in offline mode.
- Deploy slots no longer look weird on very large screen resolutions.
- Flashbangs that could sometimes kill an enemy if they hit him.
- Too many trooper radio sounds in replays.
- A bug where shields would not stop bullets coming from grazing angles.
- Snipers can no longer target VIPs.
- A bug where modded weapons would show up more than one time in the equipment menu.
 
Modding / Structure changes:
- When updating a mod, the mod.xml "description" field is no longer updated on Steam Workshop.
- Can now use additional breaching charge types on a door.
- Maximum map size is no longer hardcoded at 4096x4096, though it's still limited by the maximum texture size supported by the GPU. Recommended 8192x8192.
- Added more rendering layers (can now control which item renders on top of what item with more precision).
- All weapon mods that use bullet_trace.tga + bullet_trace_shotgun.tga should now use the .dds versions. Will remove the .tga ones in the next update.
- All weapon mods should update the firearms flare rendering layers to mimic the ones in the new equipment.xml version.
- All weapon mods should add bullet-shell-on-the-ground sounds like in equipment.xml. If your mod already added such sounds (e.g. SiC), make sure to take them out or add them using the new fields in equipment.xml.
- Graphics / Explosion sounds for flashbangs/breaching charges are now moddable. Mods that modify the flashbangs/breaching charges should modify them according to the new equipment.xml (added the explosion sounds and graphics).
- Crowbar/lock-picks added to the equipment items and can now be modded.
