1.1.9 - Fixed a dedicated server crash (`NoSuchFieldError`) when placing or breaking the Engine Core, the Fluid Combustion Chamber or the Steam Power Chamber.

1.1.8 - Added the thrust nozzle: Mounts on the front face of an Encased Fan and turns its airflow into axial thrust - far stronger than the fan on its own.

1.1.7 - Transmission peripheral: `setTargetSpeed` now accepts **negative speeds (-256 ~ 256)** and `setRatio` accepts **negative ratios** — a negative value makes the downstream rotate **opposite to the input**. Stress is now charged on the signed difference `|output − input|`, so reversing costs more stress than slowing down in the same direction.

1.1.6 - Fixed the control desk throttle clipping through the desk surface - Monitors can now be hung upside-down from ceilings : only the base and bearing flip, while the screen body (case) stays upright — hit-testing, interaction, config menu and removal all keep their ground behavior. - Added the Monitor Slab, a step-shaped monitor block with a 14×14 surface grid. Check the wiki for more details: https://zombieeggstew.github.io/ccnavigationtable-template-1.21.1/monitor/monitor-slab/

1.1.5 - Mixture now has a much stronger effect on heat output (linear heat factor `2 − m`, both lean and rich). Check the [wiki](https://zombieeggstew.github.io/ccnavigationtable-template-1.21.1/engine/temperature/) for more details. - Widened the fluid engine's economy-factor mixture window: the mixture condition is now `0.8 ≤ actual mixture ≤ 1.1` (was `|actual mixture − 1| ≤ 0.05`). - The Fluid Combustion Chamber can now burn Aeronautics' Levitite Blend fluid and Create's Chocolate fluid. Check the [wiki](https://zombieeggstew.github.io/ccnavigationtable-template-1.21.1/engine/fluid-combustion-chamber/) for more details. - Added `getAutoRichness` Lua method. Check the [wiki](https://zombieeggstew.github.io/ccnavigationtable-template-1.21.1/engine/lua-api/) for more details. - engine.getFluidTanks() now mainThread = false

1.1.4 - fluid port 0.5kg->0.25kg - Added the quick fill fluid tank and quick fill fuel vault. - Added the modular engine - Added the joystick_3 - Added the servo_bearing - Fixed cross-thread visibility on the trailing wheel mount: `steeringSignal` / `chasingYaw` / `lastChasingYaw` are now `volatile`. (The server thread writes them while CC Lua computer threads read them via `getSteering`/`getSteeringAngle`, and the client render thread reads `chasingYaw` through `getLerpedYaw`.) - Fixed a torn-snapshot window in the altitude-pressure conversion: the atmosphere curve snapshot (base pressure, anchors, Y bounds) is now published as a single immutable record through one `volatile` reference instead of four separate `volatile` fields. - Fixed `TrailingWheelMountPeripheral.equals` comparing only BlockPos: it now compares the block entity identity, so a peripheral at the same coordinates in another dimension (or a re-placed block entity after a chunk reload) is no longer treated as the same peripheral. - `_analyze_flight6.py`: guarded the half-period / full-period calculation against an empty extrema list — short or strongly damped flights no longer raise `ZeroDivisionError`. - `_verify_pressure.py`: the hard-coded `_8_delaytest` detail log is now optional (skipped with a notice when missing) instead of failing the whole analysis. - Flight Data Recorder docs now consistently describe the actual **FMC/AIC/INS** scope (INS-only bodies are recorded too) and correct the "default on" wording to "default off": Config comment, class Javadoc, en_us / zh_cn tooltips, and both wiki pages.

1.1.3 - Added free mode for the Throttle. - Added altitude-pressure conversion tools, sail aero tools, the universal drag tool and the max-cruise-altitude solver to the FMC. Check the wiki for more details. - Added the Flight Data Recorder system. - Added getVelocity / getAngleRates to the INS. - Added steering to the trailing wheel mount. Check the wiki for the control method. - Improved the Examples & Tutorials section of the wiki.

1.1.2 - Added the position light. - ccpe.sensor_system.getAngularVelocity()：world frame → Body-frame - Added the trailing wheel mount

1.1.1 - **IMPORTANT!!!** Control desk channels are now **physics-body-scoped**, Check the wiki for more details(https://zombieeggstew.github.io/ccnavigationtable-template-1.21.1/control-desk/overview/). - **!?NEWNEW?!** Added the Fluid Port - **!?NEWNEW?!** Added the Short Range Linker, Check the wiki for more - Fixed aero bearing not adjusting its mass when assembled properly - Fixed crash "Not building!" when opening the Diagram screen (Aeronautics) with a control desk inside an assembled physics body (Sable sub-level). - Interactions can no longer pass through the Monitor. - Added an optional color parameter to screen.writeField. - Added drawCells / drawText / setVisible / isVisible (Lua methods). - getPhysicsCenterOfMassRel is now relative to the FMC block center; added getPhysicsChainCenterOfMassRel. - monitor_2 can no longer be washed away by water. When dismantling a control desk carrying a monitor_2 with modules, the modules now drop to the ground.

1.1.0 - Added the Aviation Integrated Computer (AIC), Check the wiki for more details.
