Shuttle 0.1.4

Shuttle 0.1.4, based on Chromium 155.0.8059.80 (was 154.0.8037.129). This release moves Shuttle to the current
Chromium stable release, with its security fixes. Agents, the MCP server and CDP work as in 0.1.3.

Changed

• Chromium 155. Web platform, rendering and security fixes from upstream Chromium 155 stable.
• Fewer Google features shipped. Services Chromium 155 added that Shuttle doesn't use are left out: Chrome's own
  agent actuation service (Shuttle agents use CDP/MCP), Gemini critical-action records and links on the history page,
  and synced tab context. Journeys (history grouping that needs Google sync) is removed too; your history stays as
  it is.

Updating: Linux with the package repository: sudo apt update && sudo apt upgrade / sudo dnf upgrade. macOS: run the
installer again (quit Shuttle first) or replace the app. Package files and the tarball: install or extract over the old
version. Your agents, their logins and your profile stay where they are.

Get started: https://www.shuttlebrowser.com/download. Or ask your agent: "Read https://www.shuttlebrowser.com/INSTALL.md
and help me set up Shuttle."

Known limits

• macOS has no auto-update yet: run the installer again for new releases.
• By default the CDP/MCP port is localhost only, with no authentication (web pages are rejected by Origin/Host checks).
  Network mode requires a token for remote clients; traffic is plain HTTP, so use trusted networks or Tailscale/SSH.
• Linux tarball only: install two libraries first (sudo apt install libnss3 libasound2t64; Ubuntu 22.04/Debian 12:
  libasound2; Fedora: sudo dnf install nss alsa-lib). On Ubuntu 23.10+ (not WSL2) the tarball needs the bundled
  chrome-sandbox setuid helper (see README-LINUX.txt). The packages handle both.
• Open codecs only: H.264-only video won't play, and there's no Widevine.
• English UI only. macOS builds are arm64 only for now.
