The new version of UQLab (V1.3) was released on September 19, 2019 ! Congratulations to the dev team, especially @ste for the project management and coordination, and Emiliano and Moustapha for their major contributions !! Two new modules are released in V1.3: - **Reliability-based design optimization** (RBDO) allows the user to solve optimization problems (e.g. minimize a cost function) under probabilistic constraints (e.g. ensuring a sufficiently small probability of failure). This module provides a user-friendly syntax to pose RBDO problems in no time and solve them by combining any optimization algorithm, reliability analysis method and surrogate model already available in UQLab (module developed by @moustapha ) - **Vine copulas** : probabilistic models for uncertain input parameters can now be defined using C- and D-Vine copulas and block-independent structures. A powerful inference tool allows the analyst to fit a complex probabilistic model from available data automatically, which can then be used for any UQ analysis (module developed by @torree ) Moreover: - Gaussian process regression is now available in the Kriging module to handle noisy observations (developed by @damarginal) - The graphics are now coherently designed using the new [uq\_graphics library](https://uqworld.org/t/uq-graphics-a-centralized-graphics-library-for-uqlab/154) (developed by @philippe and @damarginal) New users already enjoy V1.3. The users of UQLab V1.2 will be prompted to update their install at their next run of UQLab.
