Mem0 ts-v3.1.3

ts-v3.1.3Aug 1, 2026 · 10 days ago

Mem0 Node SDK (v3.1.3)

Added 1

Add Qdrant server-side BM25 keywordSearch() with payload filter indexes, requiring Qdrant >= 1.15.2, so keyword search runs without a client-side BM25 dependency

Changed 1

RerankerFactory's default LLM reranker model is now gpt-5-mini (was gpt-4o-mini)

Fixed 5

deleteAll() now paginates through the vector store in batches of 1000 instead of listing once, so accounts with more memories than a single page no longer have the remainder silently left behind
Supabase list() now paginates past PostgREST's 1000-row cap instead of stopping at the first page
Supabase search() warns when results may have been truncated by PostgREST's 1000-row cap
Supabase initialization probe reads a row instead of writing a test vector, so Row Level Security policies that only grant read access no longer fail table verification
Honor TOGETHER_API_BASE in the Together embedder, matching the Together LLM provider, so a custom gateway URL is no longer silently ignored for embeddings

Security 1

Patched 32 high and 57 medium severity dependency vulnerabilities across the pnpm workspace via pnpm.overrides

New Features:

Vector Stores: Add Qdrant server-side BM25 keywordSearch() (requires Qdrant >= 1.15.2) plus payload filter indexes, so keyword search runs without a client-side BM25 dependency (#5851)

Bug Fixes:

Core: deleteAll() now paginates through the vector store in batches of 1000 instead of listing once, so accounts with more memories than a single page had the remainder silently left behind (#4872)
Vector Stores: Supabase list() now paginates past PostgREST's 1000-row cap instead of stopping at the first page, search() warns when results may have been truncated by that same cap, and the initialization probe reads a row instead of writing a test vector, so Row Level Security policies that only grant read access no longer fail table verification (#6695)
Embeddings: Honor TOGETHER_API_BASE in the Together embedder, matching the Together LLM provider, so a custom gateway URL is no longer silently ignored for embeddings (#6572)

Changes:

Rerankers: RerankerFactory's default LLM reranker model is now gpt-5-mini (was gpt-4o-mini) (#6703)

Security:

Dependencies: Patched 32 high and 57 medium severity dependency vulnerabilities across the pnpm workspace via pnpm.overrides (axios, brace-expansion, js-yaml, postcss, protobufjs, mongoose, tar, fast-xml-parser, thrift) (#6639)
