+- **Selective install architecture** — Manifest-driven install pipeline with `install-plan.js` and `install-apply.js` for targeted component installation. State store tracks what's installed and enables incremental updates.
+- **6 new agents** — `typescript-reviewer`, `pytorch-build-resolver`, `java-build-resolver`, `java-reviewer`, `kotlin-reviewer`, `kotlin-build-resolver` expand language coverage to 10 languages.
+- **New skills** — `pytorch-patterns` for deep learning workflows, `documentation-lookup` for API reference research, `bun-runtime` and `nextjs-turbopack` for modern JS toolchains, plus 8 operational domain skills and `mcp-server-patterns`.
+- **Session & state infrastructure** — SQLite state store with query CLI, session adapters for structured recording, skill evolution foundation for self-improving skills.
+- **Orchestration overhaul** — Harness audit scoring made deterministic, orchestration status and launcher compatibility hardened, observer loop prevention with 5-layer guard.
+- **Observer reliability** — Memory explosion fix with throttling and tail sampling, sandbox access fix, lazy-start logic, and re-entrancy guard.
+- **12 language ecosystems** — New rules for Java, PHP, Perl, Kotlin/Android/KMP, C++, and Rust join existing TypeScript, Python, Go, and common rules.
+- **Community contributions** — Korean and Chinese translations, InsAIts security hook, biome hook optimization, VideoDB skills, Evos operational skills, PowerShell installer, Antigravity IDE support.
+- **CI hardening** — 19 test failure fixes, catalog count enforcement, install manifest validation, and full test suite green.
