Release Notes

Release Date: June 6th, 2023

What’s New

We are thrilled to inform you that our Binary Data Storage Service now has compatibility with Google Cloud Storage. Additionally, we have incorporated a brand new functionality called Semantic Title Search to Discovery API. This feature allows us to retrieve results that possess titles with semantic similarity to the search query. Moreover, you have the option to customize the configuration so it highlights either the exact phrase or the specific matching words. If you have any inquiries or suggestions, please don't hesitate to reach out to our development team. Continue to read on for all new features, bug fixes, and improvements.
