What's new in BoB v0.97

BoB now speaks Chinese: the desktop app in English, Simplified (简), and Traditional (繁) with a live language toggle, and the assistant replying in the language you pick. Plus the desktop app is now the GUI, and a few backend fixes.

BoB now speaks Chinese. That’s the headline of v0.97. The rest is a cleaner GUI story and a handful of backend fixes. Here’s what changed — and what’s still on the honest-to-do list.

BoB now speaks Chinese

The desktop app is localized in English, Simplified Chinese (简), and Traditional Chinese (繁) — 172 UI strings across the three, with a restart-free language toggle right in the header (EN → 简 → 繁). Flip it and the interface changes in place; no reload.

The localization goes past the chrome. The backend now threads a per-turn locale: when you pick a non-English language, BoB is directed to reply in that language too. The desktop app sends the locale with each turn, so switching the toggle switches the language BoB answers in. Leave it on English and nothing changes — the behavior is byte-identical to before.

Two honest caveats, because this is a first localization pass:

The desktop app is now the GUI

The preview browser UI is gone. The old /ui page was a stopgap; v0.97 removes it, and the gateway now serves the JSON + WebSocket API only (hitting / returns a small info response instead of redirecting to a web page). Removing it also removes the browser localStorage session-token surface that came with it.

The GUI going forward is the Kotlin Multiplatform desktop app (bobclaw-app), with Android as a preview. One thing to be clear about: it’s a real app you build once — not a zero-install web page. You need a JDK; ./gradlew :desktopApp:run from bobclaw-app brings it up. If you’d rather not build a GUI at all, the headless front door — the CLI, the MCP server, and the JSON+WebSocket API — is unchanged and fully usable. The setup guide walks both paths.

Backend fixes and touches

Under the hood

Compose Multiplatform moved from 1.6.11 to 1.7.3 for the desktop/Android app. No change to how you install or run BoB beyond the GUI note above.

Upgrading

Nothing in your setup flow changes except the front door. If you were opening the browser UI, use the desktop app or the headless MCP/API path instead — the Setting up BoB guide is updated for v0.97 with both.
