v0.2.1

What's Changed

Scoping & data isolation

• HistoryStore.add() now accepts user_id to establish session ownership, enabling correct scoping for get_all/delete_all across Zep and Letta adapters
• Zep search() derives owner from thread metadata on cache miss for cross-restart correctness
• LettaFactAdapter raises NotSupportedError for user_id/agent_id-scoped get_all, search, and delete_all instead of silently ignoring scope
• SupermemoryFactAdapter caches fact_id → container_tag (LRU-bounded) so update/delete target the correct scope

Performance

• ChromaDocumentAdapter wraps all sync chromadb calls in asyncio.to_thread() to avoid blocking the event loop

CI

• Added GitHub Actions CI workflow running pytest on Python 3.10 and 3.12

Docs

• All history examples updated to show user_id parameter
• Letta fact docs clarified with scoping limitation section
• Zep docs corrected to use user_id consistently
