Changelog

Each release of fxbot, newest first. A release that adds migrations, bumps libfx, or needs a step by hand opens with Before upgrading. Lines for the next release collect under Unreleased, and the release workflow publishes a version's section as its notes.

0.2.1 (2026-11-02)

A website release. The app is the same as 0.2.0.

• A link to fxbot.sh shares as a preview card, with the bots, the heading, and the site's address.
• Each page of the site names its canonical address and has Open Graph and Twitter tags. The site has a sitemap and a robots.txt, and its link check covers them.

0.2.0 (2026-11-02)

Before upgrading. Migration 0002_model_lists adds a table that keeps each provider's model list, 0003_registry_entries adds two that keep a copy of GitHub's MCP registry, and 0004_skills adds one for skills. Chats and add-ons carry on.

• Skills. Bots use Agent Skills: instructions for a kind of task, read only when a task needs them. The Add-ons page's Skills tab lists fxbot's own picks (show-me, frontend-design, and grilling), tagged fxbot, and searches skills.sh, tagged skills.sh. A skill installs as skills.sh installs it, from its GitHub repository at the commit its page showed. Each bot's instructions list its skills, within 1% of the model's context window, and a skill tool reads one, which the chat shows as "Read a skill". In a chat, $, or / at the start, lists the bot's skills: the one picked goes with the message as a chip, so the bot has it without deciding to. Skills go to all bots or chosen ones, like MCP servers, and are marked Update available when their files change upstream. Nothing in a skill runs.

• The Add-ons page is a search above four tabs: Installed, Skills, MCP, and Plugins. MCP searches GitHub's MCP registry, which fxbot mirrors every hour, and Search everything adds the official registry's unmoderated results. Each entry opens on a page that shows its host (in red when it isn't on the publisher's domain), how it signs in, the keys it needs, and where it comes from, before Add. Adding by address is still there, under MCP. Plugins says they aren't in fxbot yet.

• fxbot ships with its own list of MCP servers, starting with alphaXiv and Keiro, tagged fxbot and listed first. With FXBOT_LISTS_URL set to the site that publishes it (the website's mcp-registry.json, beside skills-registry.json), fxbot reads it every hour, so the lists can grow between releases. Other cards are tagged GitHub registry or Official registry, and a server on more than one shows once, as fxbot's.

• An installed server from a registry is marked Update available, Deprecated, or Removed from the registry, and nothing changes by itself. Update to shows what the newer version changes, and moves only on Update.

• Past 40 tools reaching the bots, the Add-ons page says how many.

• A server still connecting when fxbot stops no longer writes to the database after it closes.

• Model lists outlast restarts. fxbot keeps each provider's list in Postgres and answers with it at once, fetching a fresh one behind the answer when it is over 5 minutes old; a failed refresh keeps the old list (#5).

• The chat shows how each reply came about, in order: thinking, tool calls, and text between them. A tool call reads as a sentence, such as "Searched the library" or "Ran linear_create_issue", and opens on its input and result; a failed one says so in red. Two or more steps in a row fold under one line, such as "Thought and used 2 tools", open while the bot works. Before, tool calls didn't show at all, and the thinking showed as one block.

• The model field is a picker that opens on the provider's whole list, the current model marked, and narrows as you type. Before, the browser's suggestions showed only the model already chosen. A model id the list lacks can still be typed in, and Clear empties the field.

• setup.sh stops, and says why, when another fxbot already holds its names: a database fxbot, a key in /etc/fxbot, or port 8787.

• A checkout's npm run dev runs its API on port 8788, so it runs beside a release install on one machine.

• The README shows how to serve fxbot at its own tailnet name, such as bot.<tailnet>.ts.net, as a Tailscale Service.

• fxbot has a website with its docs, in packages/website. npm run build-site builds it into out/ and checks its links.

0.1.0 (2026-11-02)

The first release.

• Bots and chats. Bots drawn as animated blobs, each with a streaming chat that survives reloads and restarts, image and text attachments, and a chat_history tool that searches its own past.
• Providers. ChatGPT, Grok, and Vercel accounts by device code, API keys, and local model servers, with every key and token sealed in Postgres.
• The library. Every file the chats hold, searchable, for people and bots.
• An installable app for phones and desktops.
• MCP servers. Tools from any remote MCP server, signed in with OAuth or a key, for all bots or chosen ones, with only the tools you allow.
• Releases. setup.sh installs a release, and Settings or npm run update moves to the next one. The database migrates forward, with a backup first.
