* <code><function></code> now checks the number of its arguments.
* <code><function></code> now checks the number of its arguments.
* New system component linear_actuator
* New system component linear_actuator
* Bug fix of Euler angles computations in FGMatrix33
* Export the fuel density to the property tree
* Export the fuel density to the property tree
* Added cyclic clipping for FCS components
* Added cyclic clipping for FCS components
* Fixed a regression which prevented the wheels rotation speed to slow down while the gears were retracted
* Added the ability to control the turbine engines spin down factor
* Added the ability to control the turbine engines spin down factor
* [Backward compatibility breakage] Gyros are now measuring rotation rates instead of rotational accelerations. Gyros that measure rotational accelerations do not exist in the real world.

* Water vapor in the atmosphere is now managed through its mass fraction rather than its partial pressure. The former being the physical quantity that is conserved when pressure and temperature vary.

* Check that there are at least 3 contacts before trying to trim on ground.
* Check that there are at least 3 contacts before trying to trim on ground.
* ECEF to ECI frame conversion has been moved from FGLocation to FGPropagate and FGInitialConditions since not all FGLocation need to manage that.
* Gravity computations have been moved to FGInertial because it is where all the constants to compute gravity are stored. This reduces the amount of data transmitted between FGInertial and FGAccelerations.
* Added optional transmission of the simulation time for FG UDP interface
* Added optional transmission of the simulation time for FG UDP interface
* Code cleanup and use more C++11 idioms (override, constexpr, range-based for loop, etc.)
* The existence of the property that is used for table independent vars is now checked during execution rather than when the XML definition is parsed. This relaxes the order in which filters, table and more generally flight controls need to be declared in the XML definition files.
* The existence of the property that is used for table independent vars is now checked during execution rather than when the XML definition is parsed. This relaxes the order in which filters, table and more generally flight controls need to be declared in the XML definition files.
* Functions <code><random/></code> and <code><urandom/></code> are no longer considered constant.
* <code><clipto type="cyclic"></code> now clips negatives values correctly.
* Fixed the artificial displacements resulting from modifications of the mass distribution while the aircraft is sitting on ground
* Electric engines RPM is now exported in UDP sockets.
* Electric engines RPM is now exported in UDP sockets.
* The sign of the XZ inertia has been fixed in the property <code>inertia/ixz-slug_ft2</code>. was just an output error, the correct XZ inertia was used internally
* The parameter <code><ignitionn2></code> now affects N2 rather than N1.  
* The parameter <code><ignitionn2></code> now affects N2 rather than N1.  
* A warning is now given when max < min in a <code><clipto></code> rather than throwing an exception
* A warning is now given when max < min in a <code><clipto></code> rather than throwing an exception
* Added the ability to log properties in a CSV file with the new fgfs executable argument <code>--jsbsim-output-directive-file</code>
* Added the ability to log properties in a CSV file with the new fgfs executable argument <code>--jsbsim-output-directive-file</code>
* Fixed uninitialized variables in FGPiston which could randomly generate invalid floating point values that would propagate to many places in JSBSim.
* Fixed a segfault occuring when changing the LOD ranges with a JSBSim aircraft
