 # Change Log
 All notable changes to HiOp are documented in this file.
 
+## Version 1.0.0: Mature solvers interfaces and execution backends
+### Notable new features
+Interfaces of various solvers reached an equilibrium point after HiOp was interfaced with multiple optimization front-ends (e.g., power grid ACOPF and SC-ACOPF problems and topology optimization) both on CPUs and GPUs. The PriDec solver reached exascale on Frontier after minor communication optimizations. The quasi-Newton interior-point solver received a couple of updates that increase robustness. The Newton interior-point solver can fully operate on GPUs with select GPU linear solvers (CUSOLVER-LU and Gingko).

 Mathematically, the above problem is identical (and has the same specification) to the NLP~\eqref{obj}-\eqref{bounds}, with the exception of the so-called ``recourse'' terms $r_i(x)$ appearing in the objective. Each of these functions are real-valued, $r_i:\mathbb{R}^n\rightarrow \mathbb{R}$, for all $i\in\{1,2,\ldots, K\}$, and can be of various order of differentiability. As of now, the recourse functions $r_i(x)$ need to be Lipschitz continuous and continuously differentiable.
-It is also possible for $r_i(x)$ to be Lipschitz and only weakly concave (with convergence guarantees). The users are encouraged to contact \Hi developers for the latest developements in this area. A compact description of the algorithm implemented by PriDec can be found in~\cite{pridec_impl} (the technical report version is available \texttt{doc/} directory).

A compact description of the mathematical algorithm implemented by PriDec can be found in~\cite{wang2023}, while the parallelization strategy can be found in~\cite{wang2021}.
 
 The input in which \Hi expects for this class of problems is a bit different than for NLPs of the form~\eqref{obj}-\eqref{bounds} and MDS NLPs introduced in the previous sections. This is mainly caused by the specifics of the primal decomposition algorithm/solver that was purposedly developed to solve~\eqref{prideobj}-\eqref{pridebounds} for large $K$ (\textit{e.g.}, $K=O(10^6)$) efficiently on a massively parallel computing platform. Nevertheless, for smaller $K$, problems of form~\eqref{prideobj}-\eqref{pridebounds} can be solved with \Hi using the sparse and MDS input interfaces.
