Island 0.8.1 (unsigned)

Fixed

• The Windows build passes its tests again (an export test kept a file open while deleting it).

---

Install: macOS: open the .dmg and drag Island to Applications. Windows: run
-setup.exe (no administrator rights needed). Linux: sudo apt install ./<file>.deb.
The .zip / .tar.gz archives are the portable builds the in-browser updater uses.

Unsigned release. These builds are not code-signed with a Developer ID or
notarized (the macOS app is ad-hoc signed; build-metadata.json: signed: false,
notarized: false, publicReleaseEligible: false). On first launch macOS asks you to
allow Island in System Settings > Privacy & Security > Open Anyway (or run
xattr -dr com.apple.quarantine /Applications/Island.app); Windows SmartScreen may
warn ("More info" > "Run anyway"). Verify each download against SHA256SUMS.txt.

Island 0.7.3 (unsigned)

Fixed

• The Windows builds compile again after the expanded icon set exceeded the platform's command-line
  limit during post-build resource staging.

Island 0.7.1 (unsigned)

Fixed

• The Linux builds compile again: native window handles are converted the same way on every
  platform (0.7.0 failed to build for linux64 and linuxarm64).

Island 0.6.2 (unsigned)

Fixed

• Compiled the Windows build as UTF-8, so window titles and the command palette no longer
  show garbled dashes and non-ASCII download names keep their bytes in the tests.

Island 0.5.1 (unsigned)

Added

• Installers next to every release archive: a macOS .dmg to drag Island onto Applications, a
  Debian/Ubuntu .deb (installs to /opt/island-browser, adds the island-browser command and
  a menu entry), and a Windows -setup.exe that installs per user without administrator rights,
  with a Start menu entry and an uninstaller.

Fixed

• macOS: a downloaded Island no longer opens as "damaged and can't be opened". The app bundle is
  now ad-hoc signed, so Gatekeeper offers "Open Anyway" in Privacy & Security instead.

Island 0.5.0 (unsigned)

Added

• Automatic builds: every push to main that changes the app builds, tests, and packages all
  six targets and publishes them as unsigned GitHub prereleases — a rolling nightly, plus a
  vX.Y.Z prerelease with the changelog notes the first time a version builds. Each release
  carries the six archives and one SHA256SUMS.txt.
• scripts/version.py notes prints one version's changelog section.
• In-browser updates (Settings > Updates): checks the GitHub releases of island-browser/island
  shortly after startup (at most once a day, ISLAND_DISABLE_UPDATES=1 to turn off) or on demand,
  downloads the platform archive, verifies it against SHA256SUMS.txt, and installs it on
  "Restart to update" with a backup and automatic rollback. SemVer pre-releases are opt-in; build
  trees and read-only installs only report new versions.
• Agent providers: choose the sidebar agent from the panel's title or Settings > Agent & tools —
  Claude Code, Codex, OpenCode, Gemini CLI, Qwen Code, Goose, or a custom command. Each shows
  whether its program was found on the PATH, with an install hint and docs link when it was not;
  switching stops a running agent and starts a new chat with the new one. ISLAND_AGENT_COMMAND
  still overrides the choice.

Changed

• The product site moved to its own repository,
  island-browser/site, and is served at
  https://island-browser.github.io/site/. It reads the version and these notes from this
  repository when it builds; scripts/version.py sync no longer touches site pages.
• The default Claude Code agent now runs npx -y @agentclientprotocol/claude-agent-acp, the
  renamed successor of the deprecated @zed-industries/claude-code-acp. A saved command equal to
  the old default switches to the Claude Code provider; any other saved command becomes the
  custom provider.
• New "Graphite" design language across the browser: neutral near-black and white surfaces,
  1px hairlines, a single blue accent, tighter radii (6/10), and a refined space palette; the
  space tint is now a faint cast on the sidebar instead of a colored wash.

Fixed

• An agent command with unbalanced quotes is refused with "check its quotes" instead of being
  handed to the login shell.
• Native builds on every target again: a GCC -Werror warning in the command palette, an MSVC
  parse error in a JSON test, the Windows arm64 runner's Visual Studio generator, and a macOS-only
  false positive in the agent descriptor-leak test.
• Windows builds: the agent tests compile with MSVC's conforming preprocessor and UTF-8 literals,
  and the macOS/Linux update script always writes /-separated paths, also when generated on a
  Windows host.
• Windows packaging recognizes the sandbox build again: CEF's bootstrap island_browser.exe
  does not name island_browser.dll, so the package step now checks that the DLL exports
  RunWinMain instead.
• Windows arm64 packaging no longer requires dxcompiler.dll and dxil.dll, which CEF ships
  only for x64.
