 ## Unreleased
 
-### Fixed
-- Docker: a clean `docker compose up --build` now reliably installs Chromium for
-  the browser tools. The Playwright browser CLI is invoked directly
-  (`node node_modules/playwright/cli.js install`) to avoid an npm bin-name
-  collision that left a from-scratch build failing with `playwright: not found`
-  (exit 127).
-- Docker on Windows (WSL2): a fresh `docker compose up --build` no longer fails
-  when `.env` is absent — `.env` is now optional. A new `.gitattributes` pins
-  shell scripts and other build-critical files to LF so a Windows checkout
-  (CRLF) builds cleanly.
+## v0.2.0 (2026-07-09)
+
+A month of work since the initial release, centered on shared workspaces,
+agent-to-agent (A2A) collaboration, and much deeper visibility into what agents
+are doing.
 
 ### Added
-- Docs: Windows/WSL quickstart notes in the README and `docs/docker.md`. The
-  browser tools run entirely inside the container (no host X server or WSLg).
+
+- **Shared workspaces** — the workspace is now the single home for everything:
+  a workspace rail, per-workspace chats with search/filtering, colors and
+  descriptions, running-count badges, workspace-scoped schedules, reusable
+  invite links, and credential sharing with scoped grants. The separate
+  "Tasks" tab is gone.
+- **Workspace tool policy** — enable/disable tools per workspace from
+  Settings → Tools; piece YAML no longer controls tool availability. Agents can
+  request a missing tool or Python package mid-task and use it as soon as you
+  approve in chat; workspaces can also pre-install extra Python packages.
+- **A2A protocol support** — publish an Agent Card, delegate skills to external
+  agents with per-delegation resource limits, run long A2A tasks non-blocking,
+  and list/revoke delegations from Settings (OAuth-based authorization server
+  underneath).
+- **SSH integration** — register SSH connections per workspace, run one-shot
+  remote operations, or open an interactive console where you and the agent
+  share one PTY (multiple sessions with tab switching).
+- **Delegate observability** — sub-agent (delegate) runs are now visible:
+  live cards with the currently running tool, result previews and abort
+  reasons, LLM token counts, child-run rollups, and a live console. LLM
+  execution itself shows live state, attempt badges, and classified
+  interruption reasons.
+- **Workspace apps** — self-contained HTML mini-apps that read/write workspace
+  files, generated with starter templates and a self-E2E pass, shareable via
+  read-only public links.
+- **Files tab upgrades** — folder create/rename/move/delete/download,
+  drag-and-drop organization, touch support, a details view (size, modified
+  time), file provenance (which task created a file), a protected `readonly/`
+  area, and automatic recognition of files you drop into the workspace.
+- **Richer previews and reading** — Excel/PowerPoint/Word preview, PDF
+  page-range reads, and a single `Read` tool that auto-detects
+  .xlsx/.docx/.pdf/.pptx/.msg.
+- **X (Twitter) research** — tools restored (new transaction-id scheme), home
+  timeline support, full text of long-form X Articles, and an "SNS deep sweep"
+  piece that triages a timeline and deep-dives each post with a clean-context
+  sub-agent.
+- **Cross-task recall** — agents can search other chats in the workspace
+  (`SearchWorkspaceTasks`), search their own long conversations, and subtasks
+  can look back at their own transcript; multi-keyword AND search included.
+- **Memory & learning** — lessons captured mid-task into persistent memory /
+  AGENTS.md, a Memory & Learning settings tab with reflection history and
+  revert, and an extended mission brief that pins user constraints and
+  decisions.
+- **English UI** — recently added screens are fully localized (i18next);
+  UI is bilingual Japanese/English throughout.
+
+### Changed
+
+- Chat screen: taller conversation viewport, a card-style auto-growing
+  composer, an always-visible context-usage gauge, and tool rows with
+  execution timestamps.
+- Research pieces split large investigations into serial delegate runs to keep
+  the orchestrator context small.
+- Context handling keeps more of the recent conversation verbatim when
+  compacting and retains longer histories on large-context models.
+- Job time limits are configurable from Settings, with clearer hard-kill
+  reasons (default 180 minutes).
+
+### Fixed
+
+- A context-limit livelock that aborted tasks seconds after start with
+  "max iterations (200) exceeded" while doing no work.
+- Docker: clean `docker compose up --build` reliably installs Chromium (npm
+  bin-name collision), and Windows/WSL2 checkouts build cleanly (`.env`
+  optional, LF pinned via `.gitattributes`).
+- HTTPS redirect kept firing after HSTS was disabled (sticky-HSTS opt-in fix).
+- Shift_JIS and other non-UTF-8 Japanese text was misdetected as binary; BOM
+  handling fixed.
+- Raw HTML in chat messages no longer breaks the conversation layout.
+- Models that require the system message first no longer error mid-task.
+- Skills whose folder name diverged from their display name could not be
+  deleted or edited.
+- Attaching a file with an existing name no longer overwrites it silently —
+  the old version is evacuated to `old/`.
