• Added Ipopt::RegisterInterruptHandler() and Ipopt::UnregisterInterruptHandler() to IpUtils.hpp to wrap handling of interrupt signals.
  Added parameter checkinterrupt (default false) to AmplTNLP constructor to enable check for interrupt signal in intermediate_callback.
• The ipopt and ipopt_sens executables and scalable problems C++ examples can now be interrupted by SIGINT/SIGHUP (systems with sigaction()) or SIGINT/SIGTERM/SIGABRT (Windows systems).
• New option mumps_mpi_communicator to specify the MPI communicator when using an MPI-enabled build of MUMPS [#790, by Alex Tyler Chapman].
• Updated build system to current autotools versions; initial support for icx/ifx and flang.
• Removed use of vsprintf and sprintf. Added IpoptData::Append_info_string(std::string,double).
• Removed use of strcpy, strncpy, strdup, and sscanf.
• Using fopen_s and getenv_s instead of fopen and getenv, respectively, if available.
• Added workaround for using Pardiso from Intel MKL 2025.0.1 [#799].
  This requires checking the MKL version at runtime and can be disabled by defining IPOPT_NO_MKLVERSIONCHECK.
