    1717The new C++ version also contains features not available in the Fortran version.
    1818 * New problem structure: The new problem structure handles general inequalities. This means that slack variables are handled by Ipopt and you no longer need to add them yourself. This also allows Ipopt to identify the slack variables and take extra steps.
    19  * Adaptive Mu Update: The new version of Ipopt includes an adaptive strategy for selecting the value of the barrier parameter. In many cases, this can reduce the number of iterations required by Ipopt.

    2120 * New linear solvers: Work is underway to interface Ipopt with other linear solvers, including open-source tools. Stay posted for more news.
