The plugin now works correctly when installed via marketplace without manual intervention. - -### Verification - -Run `pm2 info claude-mem-worker` to verify: -- **exec cwd** should be: `/Users/[username]/.claude/plugins/marketplaces/thedotmack` -- **script path** should be: `/Users/[username]/.claude/plugins/marketplaces/thedotmack/plugin/scripts/worker-service.cjs` - -## [6.0.7] - 2025-11-17 - -## Critical Hotfix: Database Migration Issue (#121) - -This is an emergency hotfix addressing a critical database migration bug that prevented claude-mem from loading for some users. - -### What was fixed - -**Issue**: Users were seeing `SqliteError: no such column: discovery_tokens` when starting Claude Code. - -**Root Cause**: The `ensureDiscoveryTokensColumn` migration was using version number 7, which was already taken by another migration (`removeSessionSummariesUniqueConstraint`). This duplicate version number caused migration tracking issues in databases that were upgraded through multiple versions. - -**Fix**: -- Changed migration version from 7 to 11 (next available) -- Added explicit schema_versions check to prevent unnecessary re-runs -- Improved error propagation and documentation - -### Upgrade Instructions - -**If you're experiencing the error:** - -Option 1 - Manual fix (preserves history): -```bash -sqlite3 ~/.claude-mem/claude-mem.db "ALTER TABLE observations ADD COLUMN discovery_tokens INTEGER DEFAULT 0; ALTER TABLE session_summaries ADD COLUMN discovery_tokens INTEGER DEFAULT 0;" -``` - -Option 2 - Delete and recreate (loses history): -```bash -rm ~/.claude-mem/claude-mem.db -# Restart Claude Code - database will recreate with correct schema -``` - -Option 3 - Fresh install: -Just upgrade to v6.0.7 and the migration will work correctly. - -### Changes - -- **Fixed**: Database migration version conflict (migration 7 โ†’ 11) (#121) -- **Improved**: Migration error handling and schema_versions tracking - -### Full Changelog - -See [CHANGELOG.md](https://github.com/thedotmack/claude-mem/blob/main/CHANGELOG.md) for complete version history. - ---- - -**Affected Users**: @liadtigloo @notmyself - this release fixes your reported issue.
