# Changelog

Notable changes to HermesOS.

The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and
HermesOS adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## 1.0.0 — 18 July 2026

First public release. HermesOS is a production-grade, composable runtime for
autonomous AI: a zero-dependency kernel that runs a graph of tasks toward a
goal, plus composable subsystems that plug into it.

**40 of 41 roadmap items** ship. **2465 tests** pass; lint, typecheck, build,
format, coverage thresholds, and `pnpm audit` are all clean. Live-validated
against real infrastructure — Docker, Postgres with pgvector, Ollama, git, and
the reachable cloud endpoints.

### Added

- **Foundations** — the kernel (missions, tasks, scheduler, event bus, plugins),
  model contracts, and the tool framework (`@hermes/kernel`, `@hermes/model`,
  `@hermes/tools`).
- **Tools** — sandboxed capabilities for filesystem, shell, HTTP, git, GitHub,
  and browser automation.
- **Models** — provider-agnostic access with an embedding service, a model
  router, and OpenAI, Anthropic, and Gemini providers, plus a context builder.
- **Runtime and interfaces** — execution engine, planner, memory, agent
  framework, scheduler, worker, REST surface, CLI framework, and Telegram.
- **Platform** — configuration, secrets, authentication, authorization, plugin
  loading, metrics, tracing, and health.
- **Production** — `apps/api`, Docker packaging, CI/CD, and load testing.

### Known gaps

- A dedicated Ollama-native provider is deferred. Ollama works today through
  the OpenAI-compatible provider.
