  • Adapt link for release 25.12
  • Added arm64/aarch64-support: Link builds now for CUDA {12,13} x {x86_64,arm64}
  • Prepare link to support GAMS miptrace-option with new C API callbacks coming with PR 779 to cuOpt.
    • New option miptrace specifies filename of GAMS solve trace (see docs). Active if non-empty string.
    • Relies on PR 779 to be merged in order to have the linkup of the callback to cuOpt compiler properly a prerequisite
  • Resolve issue Error getting solution bound for MIP without integer variables #4.
