Version 0.9.1 Release

0.9.1 Update - This minor update includes 15 commits and 31 additions/fixes.

FEATURE UPDATES

• Aerodynamic Improvements: Added Vortex Ring State to the advanced flight model. VRS is when the helicopter descends into its own downwash and renders collective increases useless. The helicopter will enter VRS when flying slower than 30kts and descending faster than 2000fpm; an extreme loss of lift and controllability will follow. To handle this, tilt the helicopter and increase speed above 30kts to exit the dirty air and “escape” the state. 
• Map Objectives: The world map now displays pickup zones, search areas, and landing zones to assist in navigation.
• Control Rebinding: You can now rebind your controls! Presets (such as RC settings) are in the works but not implemented yet.

GENERAL AND VISUAL UPDATES

• Improved performance by tightening up physics calculations; a mid range computer should see a 10-15% FPS increase.
• When shutting down on uneven terrain, the helicopter will no longer "snap" to a level position on startup
• Added menu options to restrict the gamepad camera and flip X/Y axis
• Improved sky color and made it more compatible with various late-game effects
• Force Feedback: When using a controller, you can enable rumble in the menus (still in a testing stage)
• Map now has more additions and visual changes as missions progress
• Fixed visuals and collisions with helicopter models
• Blade impact sparks should now trigger more reliably
• Menu navigation is more explicit and easy with a controller
• Added additional sounds to stormy weather
• Tweaked cargo boxes to no longer clip through the ground when attached to the hook
• Added sound cues for passenger pickup
• More visual effects for damage
• The cruise ship wake now looks more consistent

BUG FIXES

• Resetting the level after a crash no longer hangs on the loading screen
• Removed some seams in the ocean's surface

KNOWN ISSUES

• Some smoke emitters randomly start and then stop when you start a mission that isn't a smoke related one
• Control rebinding menu isn't usable with a controller
• Light helicopter rescue hoist clips through skids and is a bit too short
• Some menu options don't have sounds
