+4.0.0 (2024-05-15)
+-------------------
+* ObjectBox now supports vector search ("vector database") to enable efficient similarity searches.
+  This is particularly useful for AI/ML/RAG applications, e.g. image, audio, or text similarity.
+  Other use cases include semantic search or recommendation engines.
+  See https://docs.objectbox.io/ann-vector-search for details.
+* Adjusting the version number to match the core version (4.0); we will be aligning on major versions from now on.

 ObjectBox Embedded Database for C and C++
 =========================================
-[ObjectBox](https://objectbox.io) is a superfast C and C++ database for embedded devices (mobile and IoT), desktop and server apps.
+[ObjectBox](https://objectbox.io) is a lightweight yet powerful on-device database for objects and vectors.
 The out-of-the-box [Data Sync](https://objectbox.io/sync/) keeps data in sync across devices and any kind of backend/cloud reliably for occasionally connected devices.
 ObjectBox Data Persistence and Data Sync follows an offline-first approach and can be used on-premise as well as with a cloud setup.
