mem0

Mem0 Python SDK (v2.0.10)

New Features:

• Client: Expose expiration_date on MemoryClient.update() and AsyncMemoryClient.update() — callers can now set or clear a memory's expiration date; None is preserved and forwarded to the API (#5874)

Bug Fixes:

• Memory (OSS): Apply remove_code_blocks() to the LangChain path in async _create_procedural_memory so code fences are stripped consistently (#5711)
• Rerankers: Score HuggingFace cross-encoder results with per-document sigmoid instead of set-relative min-max, preventing a single low-score document from collapsing all relevance scores to zero (#5715)
• Core: Validate and trim entity IDs (user_id, agent_id, run_id) in delete_all() for both sync and async Memory (#5735)
• Vector Stores: Use .get() for hash and created_at in the Redis insert() and update() paths so entity payloads that omit those fields no longer raise KeyError (#5709)
• Memory: Fix scale-threshold notices not firing for Redis and search-engine backends by resolving col_info() signature differences and adding num_docs to the count-extraction lookup (#5687)
• Vector Stores: Escape special characters in Valkey FT.SEARCH tag filter values to prevent wildcard and operator injection through tenant-isolation filters (#5750)
