Ready for the release of 1.2.1 ?

[bcoconni]

I am about to push the button of the release v1.2.1. I have compiled the changelog below.
Is there anything important that is missing or should be included in this release ?

Changelog

User

• Fixed a bug in the computation of orbital parameters where the perigee argument was valid only if the inclination and eccentricity were non-zero (PR Argument of perigee only valid if both inclination and eccentricity are non-zero #981)
• Restored the ability to use the linearization feature from the console and from XML scripts (PR Linearization from console executable and xml script  #991). As a result of this change, the script 737_cruise_steady_turn_simplex.xml no longer fails.
• Fixed an error in the computation of rotation rates in the body frame (aka vPQRdot) (regression test added by PR Wrong calculation of vPQRdot in FGAccelerations class #1034 and fixed by PR Fix a mistake in vPQRdot calculation #1036)
• The documentation has been updated regarding the values that the mixture of a piston engine can be set to (PR Documentation updates. #1048 and issue Fixing the mixture for JSBSim piston aircraft #1037).
• Fixed a bug where a telnet connection could not be reopened (PR Provide possibility to reopen telnet connection #1078)
• Added the ability to change the location of thrusters via properties (PR Added ability to dynamically change thruster location via property #1073)
• The error management in socket code has been improved to intercept and report more errors. This should help the user finding errors more easily when using this feature (PR Some improvements to the socket code. #1081)
• Added the ability to modify the property ic/vw-mag-fps i.e. the initial value of the wind velocity magnitude (PR Add support for setting ic/vw-mag-fps #1093)
• Reduced the console output when debug level is zero (PR Reduce console output when debug level is zero #1092)
• The thrust augmentation command is now clamped to the range [0.0 - 1.0] (PR AugmentCmd should be clamped to [0.0..1.0] for 'augmentation method two' #1090)
• Added properties AGL-ft to display the height above the ground of each contact (PR Create AGL property for contacts #1104)
• Clarified the document of <function> to state that it can contain a single <table> element (PR Update FGFunction documentation #1131)

Distributed flight dynamics models

• The model of the Short S23 Empire has been updated.
• Fixed the initial conditions of the script ball_orbit.xml so that its orbit gets circular (i.e. its eccentricity is zero). See discussion Ball script circular orbit setup #985 for more details.
• The model of the Zeppelin NT airship a.k.a ZLT-NT has been updated.
• The model of the Submarine Scout airship has been updated.
• The license of the following files have been changed from GPLv2+ to LGPLv2.1+
  • systems/airship-mooring.xml
  • systems/airship_added_mass.xml
  • systems/hydrodynamic-planing-floats.xml
  • systems/hydrodynamic-planing.xml
  • systems/hydrodynamics.xml
  • systems/visual-reference-point-extensions.xml

Python module

• Improved the caching of property nodes for faster lookups (PR Use cached PropertyNodes in python API for property reads #993)
• The reference counting of property nodes is now shared between the C++ code and the python module. This avoids crashes due to the inadvertent deletion of pointers by the C++ code of pointers that are also used by the Python module. (PR Make the Python binding of FGPropertyNode compatible with SGSharedPtr ref counting #1000)
• Fixed the documentation of the methods FGPropertyNode.get_double_value and FGPropertyNode.set_double_value (PR Documentation updates. #1048 and issue CMAKE Configure Error on MacOS (M1 aarch64) #922).
• Made the Python module compatible with NumPy 2.0 (PR Fix incompatibilities with NumPy 2.0 #1107)

Aeromatic++

• Fixed a typo in a message printed in the console by aeromatic++ (PR Fix typo in Aeromatic++ #1002)
• Fixed the headers so that aeromatic++ can also be compiled with VS2015 (PR fix: toupper is not a member of std #1020)

Developer

• The CMake target libJSBSim now includes the list of the headers it uses for cross reference in other CMake files (PR fix: target include directories #1022).
• Some maintenance / minor changes have been done (see PR Maintenance / Minor changes #1031 and PR Maintenance / Minor changes #1050 for details).
• Replaced hardcoded buffer lengths by a computation of the length using sizeof(). This avoids potential mismatches in future updates of the files (PR Ensure consistent buffer size for snprintf #1035).
• JSBSim is now compiled and tested on MacOS M1 runners (PR Run tests on M1 MacOS runners. #1030)
• libexpat has been updgraded to 2.6.2 (PR Upgrade libexpat to 2.6.2 #1080)
• The XML element of late bound properties is now released after successful binding for memory saving (PR Release XML element when property value node was bound #1096)

Note that:

• The general use of PRs make the changelog easier to write 😄
• I have purposely skipped the PR Revamping the entire logging system and message output  #1094 (logging system revamp) from the release 1.2.1 as I consider it's still work in progress.

...as I consider it's still work in progress.

I'm sure delayed because of all the time you're spending at the Olympics? 😉

Not at the Olympics but watching them definitely 😉

Looks like a good and comprehensive summary.

Thanks, so I went ahead and v1.2.1 is now released.
