**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.

<Update label="2026-05-08" description="Memory Decay">
|
||
|
||
**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).
