- **added** — 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
- **fixed** — 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
- **fixed** — Supabase list() now paginates past PostgREST's 1000-row cap instead of stopping at the first page
- **fixed** — Supabase search() warns when results may have been truncated by PostgREST's 1000-row cap
- **fixed** — 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
- **fixed** — 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
- **changed** — RerankerFactory's default LLM reranker model is now gpt-5-mini (was gpt-4o-mini)
- **security** — 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](https://github.com/mem0ai/mem0/pull/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](https://github.com/mem0ai/mem0/pull/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](https://github.com/mem0ai/mem0/pull/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](https://github.com/mem0ai/mem0/pull/6572))

**Changes:**
- **Rerankers:** `RerankerFactory`'s default LLM reranker model is now `gpt-5-mini` (was `gpt-4o-mini`) ([#6703](https://github.com/mem0ai/mem0/pull/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](https://github.com/mem0ai/mem0/pull/6639))
