Mem0 Node SDK (v3.1.6)

on GitHub

New Features:

• Vector Stores: Add an Oracle AI Vector Search vector store (oracledb) to the OSS SDK, with pooled connections, HNSW/IVF indexes, an optional indexAccuracy target, JSON payload filtering, and six selectable distance metrics (#6690)

Bug Fixes:

• Core: Percent-escape %, &, and = in user_id, agent_id, and run_id when building the session scope key for the recent-conversation buffer, so the key stays unambiguous for ids containing those characters. Ordinary ids keep their existing key; an id already containing %, &, or = maps to a new key, so its buffer starts empty once and refills on the next add(). Stored memories are unaffected. Reported by @OfficialAbhinavSingh (#6892)
• Vector Stores: Close and clear the Oracle pool that Mem0 created when initialize() fails, and reset the cached init promise so the next call retries instead of replaying the rejection forever. A caller-supplied client is left untouched (#6839)
• Vector Stores: Validate Oracle insert() batches before touching the database: ids and payloads must match vectors in length, so a short array can no longer write rows with undefined ids or silently drop payloads (#6839)

Improvements:

• Vector Stores: Cut Oracle round trips. insert() now sends the whole batch through one executeMany() with explicit bindDefs instead of one INSERT per vector, list() reads the total from a COUNT(*) OVER () window in the same statement instead of issuing a second count query, and an unfiltered search() adds the VECTOR_INDEX_TRANSFORM hint so the vector index is used (#6835)

Security:

• Dependencies: Patched 8 high and 18 medium severity dependency vulnerabilities across the pnpm workspace via pnpm.overrides (undici, brace-expansion, ip-address) (#6847)
