Shipped August 1, mem0 v2.0.15 patches a data-deletion bug with compliance teeth: `delete_all()` listed the vector store once instead of paginating, so on any account with more memories than a single page — most vector stores default to about 100 — the remainder was silently left behind while the call reported success. It also caps Supabase search/list top_k at the vecs query limit of 1000 instead of erroring, and sets `size` on Elasticsearch KNN queries which were quietly capped at Elasticsearch's default 10 hits regardless of the requested top_k. The default LLMReranker model also moves from gpt-4o-mini to gpt-5-mini. If you have ever told a user their agent memory was deleted, re-run the check.
