Changelog

All notable changes to the Mem0 plugin will be documented in this file.

0.1.3

user_id resolution no longer derives from MEM0_API_KEY. v0.1.2 changed the resolver to fall back to "mem0-" + sha256(MEM0_API_KEY)[:12] ahead of $USER, which silently moved every existing user to a new bucket on update. Memories written under the previous $USER value became unreachable from the plugin. Resolution is now back to MEM0_USER_ID → $USER → "default".
Dropped the "regardless of which machine you're on" line from the SessionStart bootstrap, since cross-machine consolidation now requires setting MEM0_USER_ID explicitly.

The ~/.mem0/identity.json cache file is no longer read or written. Safe to delete.
If you wrote memories during the v0.1.2 window, they live under mem0-<sha256(api_key)[:12]>. To recover: temporarily export MEM0_USER_ID=mem0-<hash>, search/export, then unset.
Want a single bucket across machines (the original goal of #5076)? Set MEM0_USER_ID explicitly in your shell profile. The plugin will not auto-derive one.

Deterministic user_id resolver (_identity.sh / _identity.py) — reverted in 0.1.3, see above.
SessionStart-compact handler (capture_compact_summary.py) that stores the post-compaction summary as a memory with metadata.type=compact_summary.
Coding-taxonomy setup script (setup_coding_categories.py) — one-shot project.update(custom_categories=[...]) for architecture_decisions, anti_patterns, task_learnings, tooling_setup, bug_fixes, coding_conventions, user_preferences.
Opt-in hook logging via MEM0_DEBUG=1 → ~/.mem0/hooks.log.
mem0-mcp skill replacing the Claude-Code-specific mem0-codex skill.

session_id now written to memory metadata (on_pre_compact.py).
SessionStart bootstrap exits silently when MEM0_API_KEY is unset.
block_memory_write.sh regex tightened to MEMORY.md / .claude/memory/* — no longer blocks docs/memory/*.md.
Removed duplicate PreCompact write path (kept agent-driven, dropped the parallel Python REST entry from hooks.json / cursor-hooks.json).
Hook-side captures (session_state, compact_summary) now set expiration_date = today + 90 days.
