The original title is "RocheDB v0.5.0: Data Locality for RAG and LLM Retrieval"

Short summary

RocheDB v0.5.0 is an open-source NoSQL document and vector store written in Nim that makes data locality explicit through rings, stellar groups, and WAL locality reporting. Rings serve as both placement coordinates and retrieval scopes, while stellar groups enable reading related rings together without global secondary indexes. The release also adds attach/detach workflows, atomic batch helpers, and physical locality observability to detect layout fragmentation early.

• •Rings provide explicit logical and physical data locality for vector and document storage
• •Stellar groups enable related-data retrieval across multiple rings without secondary indexes
• •WAL locality reporting makes physical layout fragmentation observable before performance degrades
