This appears to be a release notes document for an open-source project related to a remote-controlled vehicle, likely a car or truck. The notes detail various changes and improvements made to the design and code over several months. Here's a breakdown of the changes: **Initial Changes (18 April 2019)** 1. Added support for expo steering. 2. Introduced six drive modes, which can be selected using channel 3: * Half-speed 4WD * Full-speed 4WD * Half-speed front wheel drive * Full-speed front wheel drive * Half-speed rear wheel drive * Full-speed rear wheel drive 3. Added buzzer feedback for arming state, signal lost, and driving mode. 4. Introduced a front spoiler with M8 thread to hold extra weight. 5. Strengthened the nose of the vehicle by printing it in Ninjaflex 70% infill or ABS. 6. Created a new FrontWheelHub that allows motor wiring to enter at the correct spot. 7. Added hooks for motor wiring in the front part. 8. Stiffened the pushpin and added an enlarged one to make the wheels point inward slightly. 9. Enlarged the LockPin to prevent unintended opening of the battery compartment. 10. Introduced an optional NoServoSaver part, which removes the servo saver but stiffens the steering. **Additional Changes (20 April 2019)** 1. Removed drive modes for front and rear wheel drive. 2. Added a battery voltage alarm. 3. Reduced servo expo slightly. 4. Moved holes in WheelAxisHolder to provide more strength. 5. Increased the strength of pushpins. **More Changes (22 April 2019)** 1. Introduced a new front spoiler, FrontSpoilerStrongNoseLong, with space for six M8 threaded rods and a length of 45 mm. **Further Updates (2 May 2019)** 1. Migrated from Arduino IDE to Platform IO. 2. Added support for LED strip WS2812 to indicate several states: * Armed/disarmed * Direction left/right * Throttle forward/neutral/backward 3. Changed Front Spoilers to hold more weight (12 x M8 threaded rods with length 45 mm). 4. Added a small LED cable hole to the motor cover. **More Updates (8 May 2019)** 1. Introduced an LEDStripMount to connect the LED strip to RainlightAndDiffuser. 2. Created a customized RainlightAndDiffuser with holes for the LEDStripMount. 3. Added a WheelAxleProtector (ninjaflex) to protect M5 nuts of motors. **Even More Updates (10 May 2019)** 1. Improved the WheelAxleProtector. **Yet More Updates (15 May 2019)** 1. Fixed hole position in UpperBom. **Later Updates (13 Jun 2019)** 1. Added BLHeli_s ESC settings: * Front motors without braking * Back motors with braking **Further Later Updates (10 Nov 2019)** 1. Fixed "front.stl". **Still More Updates (1 Dec 2019)** 1. Changed servo mount to support MG90S servo. 2. Modified FrontWheelHubRight and FrontWheelHubLeft to have more clearance. 3. Added support for optional gyro (GyroMount). 4. Updated program to support gyro MPU6050. **Even Later Updates (20 Dec 2019)** 1. Improved NoServoSaver.stl to have more clearance. 2. Changed ESC settings to maximize torque. **One Last Update (22 Dec 2019)** 1. Added remixed optional Raintires designed by Palmiga. **The Very Latest Update (04 Jan 2020)** 1. Introduced FrontSpoilerStrongNoseNormal. 2. Added wiring diagram (Fritzing + PNG).
