Version 6.18 (2023/05/15; pre-release)
Highlight: Feature A
Enabling / Accessing: Where available and how to access
Documentation: Where to learn more
For example:
The Dakota GUI has added many significant feature improvements over the last year. The Dakota GUI now allows you to seamlessly browse Dakota’s HDF5 database output files, as well as generate sophisticated graphical plots from HDF5 data with just a few clicks. HDF5 browsing and plot generation can also be driven within Dakota GUI by Next-Gen Workflow, a powerful tool that allows you to construct node-based workflows for complex tasks.
Enabling / Accessing: Dakota GUI ships with Dakota and is available for Windows, Mac, and RHEL7.
Documentation: An enhanced version of the Dakota GUI manual now ships with the GUI, giving you easy access to a wealth of reference material for using the GUI. The 6.11 GUI manual is also available here.

Miscellaneous Enhancements and Bugfixes
Enh:
Bug fix: Correlation matrices now receive the correct variable labels in studies that include variables from more than one category (e.g. mixture of design and aleatory uncertain).
Bug fix: Standard moments are now written correctly to HDF5 for stochastic expansion methods
Bug fix: No datasets are written to HDF5 for PDFs for zero-variance responses. This matches the console output. Previously, empty datasets were written.
