      Release Notes: The license has changed from GPL to LGPL with this release. There were numerous analysis, framework, and performance improvements along with bugfixes. New uniform and adaptive polynomial order refinement ("p-refinement") functions were provided for PCE and SC using tensor and sparse grids.

        Release Notes: The license has been changed to the GNU Lesser General Public License. The JAGUAR 2.0 graphical user interface was added for creating, editing, and running DAKOTA input files. Additional discrete range and discrete set types within design, uncertain, and state variables were added. Anisotropic sparse grids, numerically-generated orthogonal polynomials, and improved expansion tailoring for stochastic expansion UQ methods were added. New methods were added for epistemic and mixed aleatory-epistemic uncertainty quantification. Other enhancements and bugfixes were made.

          Release Notes: A new stochastic collocation method based on Lagrange interpolation. Extended quadrature and sparse grid capabilities. Additional random variable support in LHS and Nataf transformation. Generalized incremental Monte Carlo sampling. Extended polynomial chaos-based design optimization capability. New capabilities for model calibration under uncertainty. Enhanced parallelism in sequential hybrid strategy. A direct interface to APPSPACK with support for linear/nonlinear constraints. Improved support for Darwin PPC and Cygwin platforms, Intel and PGI compilers, and OpenMPI message passing.

            Release Notes: Wiener-Askey generalized polynomial chaos expansions, efficient global reliability analysis (EGRA), incremental Latin hypercube and incremental Monte Carlo sampling, and (multimodal/adaptive) importance sampling were added. The optimization methods were added and extended. A Python interface, support for failure detection/mitigation, and mixed surrogate/truth models were added. Numerous bugs were fixed.

              Release Notes: This release adds a Java frontend, an interface to the AMPL solver library, "model" as a sixth keyword specification block, and support for finer-grained reports. Active set generalization and dependency management have been improved. The memory footprint of many routines has been reduced. There are many other enhancements and extensions to methods, models, and strategies used to analyze software. Updates to third-party libraries are included. Many bugfixes. The documentation has been moved to LaTeX from the Framemaker format.
