Our community has been asking about many new features, and I am excited to share with you all that this release contains several! Just look at this feature list!

JSON support — Milvus now supports the JSON data type, seamlessly storing JSON as the accompanying vectors' metadata within your collections. You can bulk-insert JSON for large-scale ingestions and perform advanced querying and filtering operations based on the contents of your JSON fields. This JSON support also brings enhanced query performance with filters using JSON fields. Finally, you can use expressions and perform operations specifically on JSON fields within your data. This feature allows you to construct queries and apply filters based on the content and structure of your JSON fields, enabling you to extract relevant information and perform advanced data manipulation. With this support, you can leverage the expressive power of Milvus to interact with and analyze your JSON data in a more precise and flexible manner.
Dynamic schema — Allows you to handle changes to the schema dynamically.
Partition key — Allows partitioning using user-specific columns as the primary keys. This feature also removes the limits to the number of partitions you can have to help with more efficient resource utilization.
Additional features include RBAC and enabling Alibaba Cloud object store.
