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](https://docs.mem0.ai/platform/features/memory-decay). --- ### 2026-04-16 **Improvements:** - **UI:** Removed the legacy external-graph-store visualization tab, page, and its references from dashboard, sidebar, project settings, playground, and billing --- ### 2025-07-23 **Bug Fixes:** -
