Changelog

All notable changes to MAESTRO are documented here. The format is loosely based on Keep a Changelog, and the project aims to follow semantic versioning.

Unreleased

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

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/.

v0.1.0 — Initial public release (2026-06-02)

First open-source release of MAESTRO, an agent orchestration platform:

Runs tasks against any OpenAI-compatible LLM endpoint (Ollama, vLLM, …).
LLM-classified task routing into Pieces (YAML workflows) of movements.
Sandboxed tool runtime (Read/Write/Edit/Bash/Glob/Grep, Office, Web, Browser, Image, Data/SQLite, Knowledge/RAG, SSH, MCP, sub-tasks, and more).
Bash tool sandbox (bwrap-based filesystem/network/env isolation with a hardened fallback) and a declarative pre-baked Python toolchain.
Optional LLM Gateway (virtual keys, budgets, metrics), reflection-based learning, scheduled tasks, and a React web UI.
Apache-2.0 licensed.
