Mem0 Node SDK (v3.0.9)

Bug Fixes:

  • LLMs: Fix Anthropic tool_choice format — was incorrectly sent as a bare string "auto" (rejected by the API); now correctly sent as { type: "auto" }. Also fixes tool response parsing: tool_use blocks are now parsed into toolCalls objects instead of throwing. Updated default model to claude-sonnet-4-6 and default max_tokens to 2000 to match the Python provider. Added temperature, topP, and maxTokens to LLMConfig so Anthropic params can be configured (#5537)
  • Memory (OSS): Preserve custom metadata fields during update() — fields such as category, priority, and other user-defined keys were previously dropped on update; the existing payload is now spread before applying the new data (#5480)
  • Client: Preserve user-defined schema keys in createMemoryExport (#5594)

Security:

  • Dependencies: Bump esbuild to >=0.28.1 across all npm packages via pnpm overrides to remediate upstream vulnerability (#5563)
