# GemiHub Desktop v1.3.0

## What's new

- Added Codex model and reasoning-effort selectors directly to Chat, with
  minimal, low, medium, high, and xhigh options.
- Enabled Workspace file tools for Codex App Server with all, no-search, and
  off access modes from the Vault tool menu.
- Fixed restored files being overwritten by a delayed editor auto-save after
  navigating to another file and back.
- Replaced Gemini 3.6 Flash with Gemini 3.7 Flash, removed the standard Gemini
  3.5 Flash option, and retained Gemini 3.5 Flash Lite for lightweight use cases.
- Added Codex App Server model selection and read-only dynamic Workspace tools,
  including confirmation-gated file edits and active Skill tools.
- Unified in-memory checkpoints and persistent file versions in the History
  view opened from File widgets or the FileTree context menu.
- Fixed restored Markdown widgets appearing empty after restart by migrating
  legacy paths to FileRef and clearing stale external-viewer state.
- Open File widgets now refresh immediately after applying an AI-proposed file
  change instead of requiring the file to be reopened from FileTree.
- Fixed binary HTTP proxy responses so Google Drive Sync downloads Office,
  PDF, and image files through `bodyBase64` without creating empty files.
- Added a quick Timeline post button beside Launcher that opens the Timeline
  composer directly.
- Added Agent Plugins v1 support for installing portable Agent Skills and stdio
  or Streamable HTTP MCP servers from public GitHub repositories.
- Added pinned release/branch installs, update previews, enable/disable controls,
  and uninstall support for Agent Plugins.
- Hardened Agent Plugin installation with manifest, repository, commit, path,
  size, executable, and Skill metadata validation at the backend boundary.
- MCP approval and credentials are now retained during an Agent Plugin update
  only when the server connection definition is unchanged.
- Agent Plugin MCP servers are tested during installation and become available
  automatically for chat turns that activate a Skill from the same plugin.
- MCP Apps now use the standard UI initialization and tool-result notification
  handshake instead of the legacy custom notification, and enforce the
  resource and connection domains declared by MCP UI resource metadata.

GemiHub Desktop is a local-first desktop workspace that brings files, AI chat,
dashboards, workflows, memos, and plugins together in one application.

## Highlights

- **Flexible dashboards** — Arrange File, Memo List, Base, Kanban, Timeline,
  Secret Manager, Workflow, and Web widgets in multiple customizable
  dashboards.
- **Rich document workspace** — Open and work with Markdown, PDF, EPUB, HTML,
  images, text, YAML workflows, Bases, Kanban boards, and JSON Canvas files.
- **Document memos** — Save notes and quotations linked to their original file
  and location, then browse them from a shared memo timeline.
- **AI chat** — Use cloud APIs, local OpenAI-compatible providers, or supported
  CLI agents with Workspace context, RAG, Web search, and MCP integrations.
- **AI workflows** — Create and revise visual YAML workflows from natural
  language, review changes as a diff, and run interactive or automated tasks.
- **Visual editing** — Edit Markdown in Preview, WYSIWYG, or Raw mode and manage
  workflows through both a node editor and YAML.
- **Extensible plugins** — Install plugins that add commands, views, widgets,
  file handlers, and AI integrations with declared permissions.
- **Local-first security** — Workspace files remain under your control;
  encrypted files, confirmation before AI-proposed edits, Trash, and file
  history help protect important data.
