======================
Sierra C24R 2020 v1.2.9
October 4, 2026
======================

NEW FEATURE:

1. Dynamic Registration
   * When selecting the November 8888 livery, users can enter any custom tail number using the aircraft registration setting in MSFS 2020.
   * The custom registration will display on both the interior and exterior of the aircraft.
   * This is the only livery that supports dynamic registration.


UPDATES:

1. Updated the Flysimware hardware binding system.
   * Hardware bindings now identify and remember the actual hardware device instead of relying only on the simulator's joystick order.
   * Existing customer bindings are automatically preserved and migrated to the new hardware identification system.
   * If hardware is added, removed, temporarily disconnected, or reordered by the simulator, existing bindings remain associated with the correct hardware.
   * Disconnected hardware records are retained as long as bindings still exist, allowing the hardware to reconnect to its existing assignments when it becomes available again.
   * Hardware assignments now display the actual device name instead of generic Joystick 1, Joystick 2, etc.
   * Each Flysimware aircraft now uses its own dedicated hardware binding WASM and binding storage. Testing determined that a single universal WASM could be loaded by the first compatible aircraft and cause binding data to be stored with that aircraft. Although this could appear to work normally, switching between products could potentially load older or different binding configurations.
   * All supported Flysimware products will be updated to use their own dedicated hardware binding WASM.
   * An Xbox controller binding issue was also corrected for MSFS 2020 products. This issue did not affect this aircraft, but it benefits from all other improvements to the updated hardware binding system.

2. TrueSim Dynamic Dirt Effects
   * Added TrueSim dynamic dirt effects for the aircraft body and windshields.
   * Dynamic effects include dust, dirt, insect splatter, mud, and runway tar.
   * Some dirt effects will dynamically wash away depending on rain strength, while others require a full cleaning using the EFB Dynamic Dirt Effects page.


BUGS:

1. Turn Coordinator Calibration
   * The turn coordinator has been correctly calibrated and is now operating as intended.

======================
Sierra C24R 2020 v1.2.8
September 24, 2026
======================

UPDATES:

1. GNS 530 and GNS 430 Brightness Control
* Updated the GNS 530 and GNS 430 screen brightness logic to allow both GPS displays to be controlled by the panel light brightness knob.

2. Panel Light Knob
* Updated the panel light knob with a minimum setting of 1% to prevent the panel lighting system from being switched completely off.
* This also prevents the simulator flashlight from activating when the panel light knob is turned to its minimum setting.

3. Saved Lighting States
* Gear unsafe, center, left, and right gear light brightness, panel lights, and overhead lights will now correctly restore to their last saved states when the aircraft is loaded.


BUG FIXES:

1. TDS GTN 750/750Xi Electrical Logic
* Corrected an issue where pulling the GPS circuit breaker for the TDS GTN 750/750Xi would only hide the display while the unit continued to operate in the background.
* The TDS GTN 750/750Xi is now correctly tied to its assigned electrical circuit and will completely shut down when power is removed.
* When the circuit breaker is restored, the unit will now perform a fresh boot-up sequence as expected.

2. GPS 2 Circuit Breaker
* Corrected the GPS 2 circuit breaker assignment so it now properly controls the GTN 750 and GTN 750Xi.

Sierra C24R (MSFS 2020 / 2024) V1.2.6 / V1.2.7
August-31-2026
=================

New Feature:

1. Added a full cabin climate control system, along with a portable panel-mounted temperature and tank timer unit that displays Fahrenheit and Celsius and can remind you when to switch fuel tanks. The tank timer can be disabled while still using the temperature display, or the entire unit can be hidden from the panel through the EFB options.

2. Added our True Sim custom binding software to the EFB, allowing keyboard and joystick buttons to be assigned to custom aircraft controls, including switches, knobs, and levers using button-based controls. We also added a special binding that can install or remove all exterior covers with a single toggle instead of changing each cover individually through the EFB.


Updates:

1. The C24R now includes additional TruSim technology, bringing the attitude indicator and HSI to life with more realistic instrument behavior.

2. The C24R HSI has been updated to include a functional TO/FROM flag.

3. The attitude indicator has been upgraded to the Sigma-Tek S-TEC 5000 B Series and now includes a functional GYRO warning flag.

4. The CGR-30P Estimated at Destination functions now allow the pilot to select between DEST and WPT by pressing and rotating the knob. The Estimated Distance, Estimated Quantity, and Estimated Time pages will display calculations for either the selected waypoint or final destination based on this selection.

5. The aircraft now rocks more noticeably left and right while the starter is cranking, with the effect increased to better represent the vibration of the four-cylinder engine during startup.

6. Main battery capacity increased to 25.0 amp-hours, with backup battery capacity updated to 7.0 amp-hours for more accurate electrical endurance.

7. Updated the LesIsMore G5 and GTX 345 instruments by Les O'Reilly with additional features and improvements. Updated operator manuals for both instruments are included with the additional product documentation. The GTX 345 update includes expanded functions such as altitude monitoring and a "LEAVING ALTITUDE" alert system.



Bugs:

1. Fixed a GNS 530/GNS 430 indexing conflict that could cause the two GPS units to conflict over autopilot control in MSFS 2020.

2. Fixed a typo in the checklist where "quartz" was incorrectly written as "quarters."

January-1-2026
=================

Bugs:
1. GNS 530 / 430 knob animation sync fixed: Corrected an issue where certain knob animations on the GNS 530 and GNS 430 could “cross-contaminate,” causing controls on one unit to animate the opposite unit. Each unit’s knob animations are now properly isolated and behave independently.
