Highlights
- MCP SDK v2 / protocol 2026-07-28: the stdio adapter now negotiates the protocol era per connection — modern clients get the 2026-07-28 revision, current hosts keep the classic initialize handshake with zero configuration. Remote OAuth MCP audited against the 2026-07-28 spec (no SSE or DCR surface; posture in docs/REMOTE_MCP.md).
- Migration 0008 — iterative HNSW scans: namespace-filtered vector recall stays complete as namespaces multiply (pgvector ≥0.8; guarded no-op below; safe for non-superuser migration roles). Numbers 0006/0007 are intentionally reserved.
- docs/ACTIONS.md: complete HTTPS reference for all 27 actions — any language, no source-reading required.
- Optional keepalive workflow for free-tier pause mitigation (opt-in via KEEPALIVE_ENABLED variable + token secrets).
- Toolchain: TypeScript 7, zod 4, MCP SDK packages 2.0, Node 24 CI.
Upgrade from 1.2.0
Additive only: pull, npm ci, apply migration 0008 through your controlled migration process, redeploy the memory (and optional mcp) Edge Functions, and confirm health reports release 1.3.0. No schema rewrites, no breaking API changes; protocol remains v1.
