What's new

• Fixed: the macOS app reported version 1.0.1 in Finder, even in v1.0.2. The build now takes the version from the release tag, so Worm.app correctly shows 1.0.3.
• Windows installer script: Install-Worm.ps1 checks the Worm.exe checksum, then installs.
• Smaller Windows package: unused satellite-locale files are removed.
• Windows crash logging: if the app crashes on launch, the reason is now written to crash.log instead of the app closing silently.
• Build diagnostics: CI now prints readable failure details in the job summary.

Install on macOS

1. Open Worm-Installer.dmg and drag Worm.app into /Applications.
2. If Gatekeeper blocks it, go to System Settings → Privacy & Security → Open Anyway, or double-click Open-If-Blocked.command.
3. Grant Full Disk Access so Worm can scan app containers thoroughly.

Known issues

• The Windows build has been verified by compiling and by running the installer script, but has had limited testing on real Windows machines. If it fails to launch, please open an issue and attach crash.log.
