+Welcome to the latest release of Querybook 🎉.
+
+Following are the top new features we have added during the year 2023 thus far:
+
+-   **AI assistant**: Support query cell title generation, text-to-sql and query auto fix, powered by LLM.
+-   **Vector table search**: Use natural language to search a table.
+-   **Data cell/table comment**: Users can leave comments for data cells and tables.
+-   **Query optimization suggestions**: Provide a tooltip of query optimization suggestions.
+-   **User group**: Introduce user groups, which can be used as table/datadoc owner/editor.
+-   **Data element**: Introdce a new metadata `data element`, which provides semantic data meaning and can be assigned to a table column.
+-   **Stats logging**: Add support of stats logging, like number of users, number of api requests and etc.
+
+## Feature highlights
+
+### AI Assistant
+
+The LLM powered AI assistant can help on
+
+-   Query cell title generation
+-   Text to SQL
+-   Query error auto fix
+
+Please check the [guide](../user_guide/ai_assistant.md) for more details.
+
+### Vector Table Search
+
+Previously table searching is only keyword based search. Now we introduced [vector store plugin](../integrations/add_ai_assistant.md#vector-store-plugin) and added the support of searching a table by natural language.

+
+### Query Optimization Suggestions
+
+The query editor will provide optimization suggestions for some cases. Here are some predefined one for Presto/Trino
+
+-   distinct count -> approx_distinct
+-   like 'a' or like 'b' -> regexp_like(column, 'a|b')
+-   union -> union all
+
+You can create you own suggestions by following the example of [PrestoOptimizingValidator](https://github.com/pinterest/querybook/blob/c8949b21c854b367d7bf54f08fbe1a12ad4a47c2/querybook/server/lib/query_analysis/validation/validators/presto_optimizing_validator.py#L177)
+
+Check the [PR](https://github.com/pinterest/querybook/pull/1302) for more details.
+
+### User Group
+
+We introduced the support of user group. Now a user in querybook can be a single user or a user group. A table could be owned by a user group, or a datadoc can be shared to a user group(haven't implemented, PR in progress).

+
+### Data element
+
+A [data element](https://en.wikipedia.org/wiki/Data_element) is an atomic unit of data that has precise meaning or precise semantics, like country, age and etc. We added data element as a new metadata, which can be assigned to a table column to provide more meaningful info for the column.
+
+Note: it can only be synced from metastore.

+
+### Stats logging
+
+Add support of stats logging, like number of users, number of api requests and etc. Please check the [plugin](../integrations/add_stats_logger.md) for more details.

 With vector store plugin enabled, text-to-sql will also use it to find tables if tables are not provided by the user.
+
+### Initilize the Vector Index
+
+In Docker based deployments, attach to `web` or `worker` component and run
+
+    ```shell
+    python ./querybook/server/scripts/init_vector_store.py
+    ```
+
+It will add summary for all tables and sample query summary of the tables to the vector store. If you'd like to only index part of the tables, you can follow the example of `ingest_vector_index` to create your own script.
