Update 1.9

Update 1.9 aka High Caliber was released on 19th December 2019.

UN-FEATURES
First, let's get this out of the way. Unfortunately, mod support has been removed from the Android version for technical reasons. Google now requires 64-bit support. Unfortunately, mod support in SimplePlanes is dependent on Unity's version of Mono, which is limited to 32-bit. To be clear, this isn't Google's fault and it isn't Unity's fault. It's really not anyone's fault, it's just that the technologies we are using have shifted in an unfortunate way. To compensate for this, we've bundled two of the most popular mods into the game: FineTuner and Overload. Also, Nicky has integrated his Advanced Targeting and Designer Suite mods into the game.

FEATURES

 * Added new Cannon part.
 * Several customizable properties such as Caliber, Barrel Length, Muzzle Brake, Recoil, Projectile Velocity, and a whole bunch more.
 * Added new stock craft: Jackhammer, an Armored Personnel Carrier, created by @EternalDarkness.
 * Bundled Fine Tuner and Overload mods with the game, so Android users can still use them.
 * Nicky fully integrated his Advanced Targeting and Designer Suite mods into the game.
 * Advanced Targeting
 * Displays trajectory line and impact point for bombs and also for the new tank cannon.
 * Includes a Predictor quality setting for low-end devices, or if you just want to turn it off.
 * Designer Suite
 * Attachment Editor - Manually add or remove connections between parts.
 * Blueprints panel - Overlay a reference image in the background of the designer.
 * Orthographic View
 * X-Ray Vision
 * Funky Trees
 * Nicky brewed this up in his experimental laboratory. They aren't your traditional trees, but rather an expression parser so you can write actual code that is evaluated for input controllers. Intended for XML modders, these allow you to blend inputs in any way you can imagine. For example:  More details at https://www.simpleplanes.com/Forums/View/1042680/Funky-Trees.
 * Added support for switching between Metric, Imperial, and Nautical unit systems.
 * Added Ground Speed, Indicated Air Speed, and True Air Speed modes.
 * Added weapon naming and multirole weapons.
 * Added sliders for Metallic and Smoothness to paint flyout.
 * Added hex color textbox to paint flyout.
 * Added ZeroThrottle and MaxThrottle inputs.
 * Upgraded to Unity 2018.4.
 * Performance Boost on Android. The silver lining of losing mod support on Android is that the game will now run a little faster.
 * Added ability to change how parts respond to collisions (aka disable exploding parts) via XML "partCollisionResponse" attribute. The options are Default, DisconnectOnly, and None.

TWEAKS

 * Added support for the Dev Console on mobile (tap settings header x5 to activate and then 3-finger tap to open/close).
 * Tweaked touchdown physics and added smoke effect.
 * Added Tournament Validator to aircraft properties.
 * Added ignitionDelay attribute to Missiles.
 * Added waterproof attribute to Missiles.
 * Added shortestAngle property to Rotator.
 * Added hingeOffset parameter to Rotator.
 * Fixed normals on hemispheres.

BUG FIXES

 * Fixed bug causing hubHeadScale to not react properly w/prop blur.
 * Fixed a bug with mirroring small parts sitting on the mirror plane.
 * Fixed issue w/low-pass filter on explosion SFX.
 * Fixed bug causing explosion SFX delay to be based on craft's position instead of the camera.
