Check the changelog for details

ObjectBox C and C++ 4.0.2

• Made closing the store more robust; e.g. it waits for ongoing queries and transactions to finish
  (please still ensure to clean up properly on your side, this is an additional safety net)
• Made Box API more robust when racing against store closing
• Improved C++ APIs for nearest neighbor search (query building etc.)
• Some minor HNSW performance improvements
• Add "vectorsearch-cities" example

Sync

• Fixed a serious regression; please update to the latest version asap!
• Added a special compression for tiny transactions
• Embedded clusters (note: the cluster feature may not come with all editions of the library)
• Add FlatBuffers based configuration for Sync Server

ObjectBox 4.0.1

• Query: "visit with score" added, so you can consume vector search results one-by-one with a visitor callback

ObjectBox 4.0 Vector Search

• 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.
