+# Changelog
+
+All notable changes to Project Workspace are documented here.
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
+
+## [2.0.0] — 2026-04-20
+
+**Zero-fork release.** Clone, don't fork. Project Workspace now runs on vanilla `pip install hermes-agent` with no patches, no drift, no custom gateway required.
+
+### Added
+- **Zero-fork architecture** — dual gateway/dashboard routing; workspace talks directly to vanilla `hermes-agent` 0.10.0+ via standard endpoints (`/v1/models`, `/api/sessions`, `/api/skills`, `/api/config`, `/api/jobs`)
+- **One-liner curl installer** — `curl -fsSL … | bash` provisions workspace + gateway + defaults
+- **Hermes-Nous theme** — dark + light editorial variants with cobalt/paper surface pass, thin 1px architectural borders, editorial type accents
+- **Conductor** (`/conductor`) — mission-control surface ported from Clawsuite; spawn missions, assign workers, watch live output and costs
+- **Operations** (`/operations`) — agent registry / sessions manager ported from Clawsuite; pause, steer, kill live agents with role and model insight
+- **Synthesized tool pills** — inline tool-call rendering from dashboard stream markers when running against zero-fork gateway
+- **Landing parity pass** — hero, features, screenshots, setup, OG image, mobile theme toggle
+- **Task board status vs. assignee** decoupling
+- **Local-model chat session persistence** — local sessions appear in history + session list
+- **Memory is local-fs first** — honors `HERMES_HOME`, no gateway dependency
+- **Splash + screenshots refresh** — Conductor, Dashboard, Tasks, Jobs captured in new editorial theme
+
+### Changed
+- **Model picker** — fetches from gateway (`~/.hermes/models.json` for user-configured models), matches OCPlatform behavior; shows only configured providers instead of all upstream
+- **`enhanced-fork` mode label** no longer implies a fork is required; it indicates streaming route availability on vanilla gateway
+- **Dashboard + enhanced-chat capabilities** marked optional; missing endpoints no longer trigger warnings
+- **Feature-gate + install copy** — all fork-era references purged
+- **Theme family allowlist** — `hermes-nous` promoted to the enterprise allowlist
+- **Session pill** — solid dark-mode background, matches model selector
+
+### Fixed
+- Duplicate responses and disappearing history on interrupt (#62)
+- Portable-mode double user message, uncleaned timeouts, orphaned unregister callbacks
+- Local model selection actually propagates to chat (no silent fallback)
+- Strip provider prefix correctly for local routing
+- Dashboard token injection on `/` (not `/index.html`)
+- Onboarding no longer stacks behind workspace shell
+- Root bootstrap guards against uncaught errors
+- Preserve assistant text during tool-call streaming
+- Installer output uses defined escape vars (removed undefined BOLD/RESET)
+
+### Removed
+- All references to the legacy "enhanced fork" as a requirement
+- Stale fork-era gateway instructions and feature-gate copy
