<Update label="2026-05-13" description="">

**New Features:**
- **Memory:** Added Temporal Reasoning for Platform v3 to improve ranking for time-aware queries such as `last week`, `upcoming`, `right now`, and `as of ...`
- **Search:** Added `reference_date` support to anchor relative temporal queries for tests, backfills, and reproducible demos

**Improvements:**
- **API:** Temporal reasoning preserves the normal client response shape for search and get-all results

</Update>

<Update label="2026-05-04" description="">

**New Features:**
- **Memory Decay:** Per-project search-time ranking bias that boosts recently-used memories and gently dampens stale ones. Opt-in via `decay` on the project endpoint; off by default. The scaling factor stays in `0.3×–1.5×`, the public `score` remains clamped to `[0, 1]`, and the bias never filters a candidate out. See [Memory Decay docs](/platform/features/memory-decay).
