JSBSim has been renamed JSBSim.py and now has the same features than the binary executable JSBSim.exe.System and Engines were missing in the previous release (issue #687)>=3.8 which allows using these binary wheels with Apple Silicon chips.eTemperature and ePressure are now derived from the Python module enum.__ which according to Python programming guidelines are meant to be private methods. So you were warned !JSBSIM_STATIC_LINK since JSBSim is supplied as a static library in the Windows installer (PR #735).Messages feature as it was unused and was using a static member that could lead to a segmentation fault when using several instances of FGFDMExec (issue #666)jsbsim.pyx are modified.CMAKE_SOURCE_DIR by PROJECT_SOURCE_DIR to allow JSBSim being built using CMAKE FetchContent (issue #684)win32api module has been removed to build JSBSim Python module on Windows.static member (issue #666)FGRealValue, FGParameter, FGParameterValue, FGCondition.JSBSim version 1.1.12

setuptools to build (work in progress)jsbsim.pyx instead of the Cython output jsbsim.cxx. This allows having consistent input data if the local version of Cython is different than the one used by JSBSim while building the source package..editorconfig file to set coding conventions for editors.distutils to setuptools (still work in progress).libexpat library).JSBSim version 1.1.11

This is the last release of JSBSim that supports Python 3.6. Python 3.6 has reached its end of life and is no longer supported by the Python Foundation (see PEP494). Please upgrade to Python 3.7 or higher.
TrimFailureException is now thrown when trim fails. This eases the detection of the trim failure (previously the exception message needed to be checked).<waypoint> control element (PR #536)ic/gamma-deg) (PR #545)<table> elements. Anything different than numbers and spaces/tabs will be rejected.<location> and <orientation> in engines is now officially dropped (PR #559, #561 and #563). These elements were deprecated long ago in favor of the corresponding elements <location> and <orientation> in thrusters. Therefore the code removed is no-op.JSBSimSimulinkCompile.m that builds the MATLAB S-function is now set to be executed immediately after the installer JSBSim-setup.exe has been run and no longer need manual updates before being run.precision such as <output precision="8"> (PR #579)FGFDMExec: SetOutputPath and GetOutputPath to specify the path to which the output files will be written.FGFDMExec.set_root_dir() no longer alters the aircraft, engine and system paths. This is now the same behavior than its C++ counterpart FGFDMExec::SetRootDir.JSBSim::BaseException. There still exist std::string exceptions thrown by JSBSim. Cleanup is still in progress.exit() or abort(). Exceptions are thrown instead. This gives the calling application an opportunity to gracefully recover.distutils will be deprecated for Python 3.11, the migration to setuptools has been started. There are still a number of distutils features which have no equivalent to setuptools so this is work in progress.setup.py to be executed on multiple platforms (removed some hardcoded statements)SGPropertyNode:getName() is no longer used as it has been dropped from the official SimGear library. This allows remaining compatible with FlightGear.<input> and <output> elements are read from a file, JSBSim now checks that the file can be read before reading it, otherwise an exception is thrown. This avoids SEGFAULTs.JSBSim version 1.1.10

<planet> to be propagated to the initial conditions.<planet> can now be specified by the tags <equatorial_radius> and <polar_radius> which are more self explanatory than <semimajor_axis> and <semiminor_axis> (which are still valid).FGTable: the file name and line number where the error occurred are now printed.<input> tags for flight controls such as <pure_gain> (issue #497). This avoids a crash when some or all <input> elements are missing.xy, xz, yz) in <mass_balance> (see PR #502).

FGTable instances were not untied from the property manager during their destruction. This could lead to segmentation faults when the property manager was later destroyed.FGTable are now instances of the TableException class.setup.py is no longer changing the current directory.INSTALL_PYTHON_MODULE has been renamed INSTALL_JSBSIM_PYTHON_MODULE. The former being too generic, this avois potential name clashes with other modules.admin folder:
XML_mass_update.py which allows automatically updating selected XML files in the aircraft data. It has avoided manual updates for the aircraft models which have been updated with the new XML attribute negated_crossproduct_inertia.prepare_test_release.sh which modifies JSBSim to dry run a test release 0.99.xx to be published to TestPyPI

load_ic and load_script now raise a FileNotFoundError exception when called on non existing files. This avoids the Python interpreter being killed when specifying a wrong path (or filename) to these methods.propulsion/fuel_freeze to freeze fuel consumption (PR #462). This can be used for simulations that require the aircraft mass to remain constant.DONT_EXECUTE_RUN_IC that can be specified to FGFDMExec::ResetToInitialConditions (PR #466).
