Gekko v1.3.0 introduces several enhancements aimed at expanding modeling capabilities and improving user experience. This release adds energy dispatch optimization benchmark problems available through a new Jupyter notebook, along with the integration of tree-based models into the ML.py module, complete with accompanying documentation. The solver extension package now includes more descriptive error handling, aiding in troubleshooting and interpretation of solver feedback. Connectivity has been improved with an updated websocket address for GenAI Gekko support and a new GenAI Support Agent that enables real-time streaming responses in Jupyter notebooks and console applications. Additionally, the release resolves Issue #163, which previously caused the final solver option to be ignored in local solves, and updates the LICENSE file to the latest version of the open-source MIT license.
