+== Release 4.0.0 (Q1 2025)
 
 === New Features
 
-==== Array UNNEST and the Array Index
+==== Version Vectors
 
-You can use UNNEST in queries to unpack arrays within a document into individual rows. This capability makes it possible to join them with their parent object in the query.
+NOTE: TODO
 
-You can use UNNEST within the FROM clause. 
-You can chain UNNEST to perform multi-level UNNEST.
+==== Mobile XDCR Coexistence
 
-You can also use a new type of index, the Array Index, to allow querying with UNNEST more efficiently.
+NOTE: TODO
 
-For more information about Array UNNEST, see:

-
-IMPORTANT: Databases upgraded from 3.1.x to 3.2.x cannot be downgraded. 
-
-
-=== New Features
-
-==== Vector Search
-
-[IMPORTANT] 
---
-Vector Search is available only for 64-bit architectures and
-Intel processors that support the Advanced Vector Extensions 2 (AVX2) instruction set.
-To verify whether your device supports the AVX2 instructions set, https://www.intel.com/content/www/us/en/support/articles/000090473/processors/intel-core-processors.html[follow these instructions.] 
---
-
-Vector Search is now available on Couchbase Lite for all platforms.
-Vector Search is a sophisticated data retrieval technique that focuses on matching the contextual meanings of search queries and data entries, rather than simple text matching.
-Vectors are represented by arrays of numbers known as embeddings, which are generated by Large Language Models (LLMs) to represent objects such as text, images, and audio.
-You can use Vector Search to efficiently find similar items or content based on the similarity of their vector representations. 
-This is useful for reducing the cost per query, performing semantic or similarity search, providing recommendations among others.
