Changes in version 2025.1.0 (2026-01-15)                

    o   Added the return of convergence code when only equality constraints are present in constrOptim.nl

                Changes in version 2015.3-1 (2015-03-06)                

    o   Added `nlminb? as an algorithm for the inner loop optimization. 

    o   Also added an option for checking the second-order KKT condition called `kkt2.check? which is TRUE/FALSE. The default is TRUE, but can be set to FALSE in problems where hessian evaluation can be time consuming. 

                Changes in version 2011.9-1 (2012-10-29)                

    o   Added `ilack.max' as a control parameter and increased it to 6 (it was previously hard coded and set to 3)

                Changes in version 2011.3-1 (2011-03-24)                

    o   Fixed a bug in `auglag' related to KKT2 condition when eigenvalues of Hessian can be complex numbers.  
	This bug occured in 3 functions: auglag1, auglag2, and auglag3.

               Changes in version 2010.10-1 (2010-10-15)                

    o   Added the Hessian computation in `auglag'.  

    o   Added checks for the first- and second-order KKT conditions in `auglag'.  

    o   Two of the convergence messages in `constrOptim.nl' where eliminated, because these were misleading.
