--- title: "Highlights" description: "Major product launches, headline features, and milestones for Mem0." mode: "wide" --- **SDK Memory Expiration: Expiring Memories Across Python and TypeScript** The latest SDK releases add first-class expiration controls to memory writes, updates, and reads, plus new TypeScript provider coverage for production deployments. - **Python client updates:** `MemoryClient.update()` and `AsyncMemoryClient.update()` now accept `expiration_date`, including `None` to clear an existing expiration. - **TypeScript client updates:** `AddMemoryOptions`, `update()`, and `Memory` now support `expirationDate`; `search()` and `getAll()` can include expired memories with `showExpired`. - **New TypeScript LLM providers:** `MiniMaxLLM` and `LiteLLM` are now available for OpenAI-compatible MiniMax and LiteLLM proxy deployments. - **PGVector deployment flexibility:** TypeScript PGVector config now supports `connectionString` and `ssl`, so apps can use a managed Postgres URI instead of separate connection fields. See [SDK & Tools](/changelog/sdk) for version details and PR links. **Temporal Reasoning: Time-Aware Retrieval for Platform v3** Mem0 Platform v3 can now interpret time-aware memories and queries so assistants retrieve the right information for questions about the past, upcoming plans, and current state. - **Search intent parsing:** Queries like `last week`, `upcoming`, `right now`, and `as of March 2025` now resolve against memory timestamps automatically. - **Default v3 behavior:** No per-request toggle is needed for v3 writes or searches. - **Deterministic testing:** Pass `reference_date` to anchor relative phrases in tests, backfills, and demos. - **Stable API shape:** Temporal reasoning changes ranking, not the client response contract. See [Temporal Reasoning](/platform/features/temporal-reasoning) for usage details. **Memory Decay: Recently-Used Memories Surface Higher** Per-project search-time ranking bias that boosts recently-touched memories and gently dampens stale ones. Off by default; opt in per project via the `decay` field on the project endpoint, or via `client.project.update(decay=True)` in the SDKs (Python `v2.0.2` / TypeScript `v3.0.3`). - **Soft bias, never a filter.** The scaling factor stays in `0.3×–1.5×`. Decay can reorder candidates but never removes them; anything that surfaced before decay can still surface after. - **Reinforcement loop.** Every memory returned in a search has its access history updated, so frequently-used facts naturally float to the top over time. - **Public score still clamped to `[0, 1]`.** Existing API contract preserved; no client-side changes needed. - **v3 search only**, fully reversible. See [Memory Decay docs](/platform/features/memory-decay). **New Memory Algorithm: State-of-the-Art Accuracy at ~3-4x Lower Cost** Ground-up rewrite of the memory pipeline with 20+ point benchmark improvements: - **LoCoMo:** 71.4 → **91.6** (+20) for multi-turn conversation recall. - **LongMemEval:** 67.8 → **93.4** (+26) for long-term memory across sessions. - **BEAM (1M tokens):** **64.1** on production-scale memory evaluation. - **Agent memories:** Assistant recall moves from 46% to **100%**. - **Temporal reasoning:** "Where did I live before SF?" improves from 51% to **93%**. - **Lower token use:** Retrieval stays under 7K tokens versus 25K+ for full-context approaches. - **ADD-only extraction:** Memories accumulate; nothing is overwritten or deleted. - **Hybrid retrieval:** Semantic search, BM25 keyword search, and entity boost are scored in parallel. - **Graph memory (built-in)**: entities extracted, embedded, and linked across memories, with no external graph store required Breaking changes: external graph stores removed from OSS (replaced by built-in graph memory), `search()` defaults changed, deprecated params removed. See [migration guide](/migration/oss-v2-to-v3). **Mem0 Skill Graph: In-Context Documentation for AI Agents** AI coding agents in Claude Code, Cursor, and Codex can now access Mem0 knowledge directly in their workflow without leaving the editor. Three interconnected skills launched: - **mem0 Core Skill:** Python and TypeScript SDK reference, REST API patterns, and integration guides for LangChain, CrewAI, Autogen, and more. - **mem0-cli Skill:** Terminal command reference, configuration walkthroughs, and CI/CD recipes. - **mem0-vercel-ai-sdk Skill:** Vercel AI SDK provider API, memory-augmented generation patterns, and multi-provider setup. **Official Mem0 CLI: Now on PyPI and npm** A full-featured command-line interface for Mem0, available in both Python and Node.js: - **Install:** `pip install mem0-cli` or `npm install -g @mem0/cli` - **Full command suite:** `add`, `search`, `list`, `get`, `update`, `delete`, `import`, `config`, `init`, `status`, `entity`, `event`. - **Interactive setup:** `mem0 init` supports email verification and direct API key entry. - **Runtime coverage:** Works with Mem0 Platform and self-hosted OSS modes. - **Automation support:** Use `--json` for CI/CD pipelines and agent workflows. - **Dual implementation:** Same commands and behavior across Python and Node.js. **OpenClaw Plugin: Production-Ready** The OpenClaw Mem0 plugin went from initial release to production-ready in one week (v1.0.0 → v1.0.4): - **Skills-based memory architecture:** New extraction pipeline with skill-loader, batched extraction, and domain-aware memory triage. - **Dream gate:** Automatic memory consolidation during idle periods for higher-quality long-term recall. - **Interactive CLI:** `openclaw mem0 init`, `status`, `config`, `import`, and `event` commands. - **Unified tool naming:** `memory_add` and `memory_delete` replace four legacy tools and match the platform API. - **Security hardened:** Path traversal protection, pinned dependencies, and 329 tests across 10 files. **Mem0 Plugin for Claude Code, Cursor, and Codex** Launched a unified Mem0 plugin across three major AI development environments: Claude Code and Cursor first (March 25), then Codex (April 2). - **9 MCP memory tools:** Add, search, get, update, delete, bulk delete, and entity management via `mcp.mem0.ai`. - **Lifecycle hooks:** Automatic memory capture at session start, context compaction, task completion, and session end. - **Cloud MCP server:** Managed endpoint replaces local MCP and Smithery setup. - **Streamable HTTP transport:** New MCP transport protocol for real-time streaming. - **Codex-specific skill:** Dedicated skill in `mem0-plugin/skills/mem0-codex` for Codex workflows. **Apache AGE, Turbopuffer, MiniMax, and pgvector for Node.js** Major expansion of the provider ecosystem: - **Apache AGE:** New graph store support, bringing the total to 4 graph store backends (Neo4j, Memgraph, Kuzu, Apache AGE). **Note:** All external graph store backends (Neo4j, Memgraph, Kuzu, Apache AGE) were subsequently removed in v2.0.0 (2026-04-14). Graph memory is now built-in entity linking with no external graph store required; see the [v2.0.0 entry above](#mem0-sdk-v2-0-0-v3-0-0). - **Turbopuffer:** New vector database provider for Python SDK. - **MiniMax:** New LLM provider with dedicated AWS Bedrock support. - **pgvector for Node.js:** PostgreSQL vector support added to the TypeScript OSS SDK. - **Reasoning models:** `reasoning_effort` parameter for OpenAI o1/o3-style models. **Mem0 Platform Skill on skills.sh** First skill launch: a dedicated Mem0 skill providing platform API reference, quickstart patterns, and integration examples directly inside agent sessions. Available on [skills.sh](https://skills.sh) for any compatible AI coding agent.
