• Switched client SDK parameters from snake_case to camelCase for consistency (#4776)
• Removed deprecated parameters across LLMs, embeddings, vector stores, and graphs (#4740)

Previous Release

• v2.4.6 (2026-04-06)

Mem0 OpenClaw Plugin (v1.0.6)

Mem0 OpenClaw Plugin (v1.0.6)

Bug Fixes:

• Telemetry: Replaced shared "anonymous-openclaw" fallback with a persistent per-machine random hash (openclaw-anon-<uuid>), so anonymous plugin users are counted individually in PostHog (#4790)
• Telemetry: Added PostHog $identify event on first authenticated run to stitch anonymous history onto the authenticated profile (#4790)
• Telemetry: Fixed event loss on short-lived CLI invocations — added beforeExit handler to flush queued events before the process exits (#4790)
• Telemetry: Added lazy /v1/ping/ email resolution so users who configure API key outside mem0 init show as their email in PostHog, not an md5 hash (#4790)
• Telemetry: Unified CLI event prefix from openclaw.<cmd> to openclaw.cli.<cmd> on the needsSetup branch to match the authenticated branch (#4790)

Improvements:

• API: Added source: "OPENCLAW" to all provider calls (add, search, getAll) across tools, CLI commands, recall, and the OSS backend adapter (#4790)

Mem0 Python CLI (v0.2.3)

Mem0 Python CLI (v0.2.3)

Bug Fixes:

• Telemetry: Replaced shared "anonymous-cli" fallback with a persistent per-machine random hash (cli-anon-<uuid>), so anonymous CLI users are counted individually in PostHog instead of collapsing into one identity (#4789)
• Telemetry: Added PostHog $identify event on first authenticated run to stitch pre-signup anonymous history onto the authenticated user profile (#4789)

Improvements:

• API: All API calls now include source=CLI in request bodies (POST/PUT) and query params (GET/DELETE) for server-side attribution (#4789)

Mem0 OpenClaw Plugin (v1.0.5)

Mem0 OpenClaw Plugin (v1.0.5)

Fixed

• Init interactive choice bug: Fixed number selection in openclaw mem0 init — entering 1/2/3 now correctly selects the corresponding option (was broken by readline prefill concatenating with user input)
• OSS pgvector crash ([#4727]): Fixed "Client has already been connected" cascade when using pgvector in OSS mode. The warmup call swallowed errors leaving a half-initialized pg client; concurrent recall/capture then all hit client.connect() on the same client. Fix: let warmup errors propagate (so initPromise resets and retries with a fresh Memory + fresh pg client) and build fresh config objects per attempt instead of mutating shared state.

Removed

• orgId / projectId config parameters: Removed from config schema, CLI (config show/get/set), init display, and providers. The API key is project-scoped, so separate org/project IDs are unnecessary and could cause access errors if mismatched.
• enableGraph config parameter: Removed from all config surfaces, providers, backend, and tools. Graph memory is being deprecated — removing the flag avoids unnecessary exposure.
