From bb8600a0a8e1f805410a78a45f9836a72a4e3fcf Mon Sep 17 00:00:00 2001 From: Lakshman Patel Date: Tue, 14 Jul 2026 01:03:23 +0530 Subject: [PATCH 1/3] chore(release): yaad 0.2.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bump VERSION 0.1.4 -> 0.2.0 and fold the Unreleased changelog entries under a dated [0.2.0] section. 0.2.0 is a minor bump: large unreleased feature block (~20 items) since the version re-baseline, plus a production-hardening pass to top-50 OSS parity: Changed: - Version re-baselined to 0.1.0 across server, sdk/python, sdk/typescript, api/openapi.yaml; internal/version now reads VERSION via go:embed at compile time (pure go build reports correct version, no ldflags). Removed: - install.sh (no binary ship), Formula/yaad.rb (no releases), deploy/docker/docker-compose.yml + .dockerignore (no Dockerfile — yaad is library-only). Security: - Stopped tracking the per-installation .yaad/integrity.key HMAC key; expanded .gitignore for local DB + Go build caches. Added: - Worktree-aware memory sharing; LLM-assisted entity extraction (opt-in); temporal fact-validity windows; gRPC/SSE WatchMemories streaming; versions/rollback CLI; ADD-only ingestion mode; subagent-scoped memory; sleep-time consolidation; semantic boundaries; non-destructive decay; config validation; spatial memory tiers (hot/warm/cold). Production Hardening: - golangci-lint v2 strict config, unchecked-error fixes, dead-code removal; CODE_OF_CONDUCT, .gitattributes, .github PR/issue templates.
