Proto v0.2.67

Important

macOS launch repair: the signed and notarized macOS assets were rebuilt on 13 August 2026 to remove an unsupported entitlement that could cause macOS to reject the app or offer to move it to Bin. If you downloaded v0.2.67 earlier, discard that DMG and download the repaired macOS build again. Because the version remains 0.2.67, existing clients will not detect this replacement as a newer automatic update.

Proto v0.2.66-petri-canary.7.1

Petri canary for proto-team validation.

• macOS: Developer ID signed, Apple-notarized, stapled, and Gatekeeper accepted
• macOS: repaired Developer ID entitlements; launch regression checked during packaging
• Windows: UNSIGNED CANARY; packaged-daemon and installer smoke tests passed
• Windows users will see the normal unsigned-app warning

The macOS source includes the launch entitlement repair. Windows reuses the previously smoke-tested unsigned canary because the repair is macOS-only.

Proto v0.2.66

A cleaner start with browser context ready

Proto now makes first-time setup easier to finish, brings signed-in browser profiles across in one pass, and keeps Live App changes under your control.

What’s new

• Import multiple profiles across installed browsers in one pass, with familiar browser icons and a new-tab import entry point.
• Keep the current Live App preview intact until you choose Refresh, with a clear notice when updated results are ready.
• Keep first-run setup actions reachable in shorter windows, with steadier provider and model setup.

Downloads

• macOS Apple silicon: signed and notarized DMG
• Windows x64: updater-signed installer; intentionally not Authenticode-signed because the Windows certificate is not configured
• Linux x64: AppImage
• CLI: npm-compatible tarball

Proto v0.2.65

A faster Proto that stays close at hand

Proto now keeps active work easier to reach, carries browser context between tasks, and moves more smoothly through demanding desktop sessions.

What is new

• macOS menu bar: open running chats, requests that need input, and recent work while Proto is in the background.
• Persistent browser sessions: keep imported signed-in sessions between tasks and manage them from Settings.
• Broader computer use: verify visible results, use clipboard and application-menu actions, and launch Windows apps more reliably.
• Desktop performance: smoother resizing, more responsive long conversations, and lower memory pressure from inactive browser views and large results.

Downloads

• macOS Apple silicon: signed and notarized DMG, plus signed automatic-update archive.
• Windows x64: updater-signed installer published under versioned and stable names; this release is intentionally not Authenticode-signed.
• Linux x64: AppImage with updater signature.
• CLI: versioned and stable npm-compatible tarballs.

Proto v0.2.63
