This minor release adds support for integrating NeMo Guardrails with NVIDIA AI Endpoints and Vertex AI. It also introduces the research overview page, which guides the development of future guardrails. Last but not least, it adds another round of improvements for Colang 2.0 and multiple getting-started examples.

Colang 2.0 is the next version of Colang and will replace Colang 1.0 in a future release. It adds a more powerful flow engine, improved syntax, multi-modal support, parallelism for actions and flows, a standard library of flows, and more. This release still targets alpha testers and does not include the new documentation, which will be added in 0.9.0. Colang 2.0 and 1.0 will be supported side-by-side until Colang 1.0 is deprecated and removed.
