MemPalace/mempalace v3.4.0

on GitHub

v3.4.0 — pluggable backends, Docker, and reliability fixes

Features

• Pluggable vector backends — Qdrant, pgvector, and sqlite_exact alongside the default ChromaDB, selectable via MEMPALACE_BACKEND / --backend.
• Docker images (CPU + GPU) for the MCP server and CLI.
• mempalace migrate-wings — one-time migration that normalizes legacy wing names (strip leading/trailing separators) so pre-upgrade palaces stay discoverable. See docs/recovery/wing-name-migration.md.
• Known-systems lexicon keeps multi-word product names atomic in entity detection.

Fixes

• embeddinggemma (the default model) now works with ChromaDB 1.5.x — semantic search was silently failing on fresh installs.
• Prevent silent data loss from drawer_id hash collisions.
• Importing mcp_server no longer recreates ~/.mempalace (respects the privacy kill-switch).
• diary_write accepts a content alias and restores the missing-parameter diagnostic.
• Explicit-vector backends handle single-document inputs correctly.

Infrastructure

• PyPI publishing via GitHub Actions Trusted Publishing (OIDC), gated by manual approval.
