Framework 1.5.1

Framework 1.5.1

Adds the Windows launcher handoff needed by the independently versioned Thunderstore bootstrap. The launcher acknowledges readiness, waits for the originating game to exit before installation, and preserves the durable bootstrap target in Start menu and Steam shortcuts.

The framework runtime is unchanged apart from its version. Existing update choices, pins, managed mods, and the normal marketplace remain in use. Compatible stable clients can receive this release; existing standalone launchers are not automatically replaced by the framework updater.

Platform and testing status

Windows setup is a tester preview: the complete Thunderstore-to-game flow has not been tested in a running Windows game. Automated launcher/helper and installer checks passed on Windows, macOS, and Ubuntu, and Unity-free CI passed. No new live-game smoke was performed for this release. Windows and Linux/Proton gameplay remain unverified. macOS downloads are not notarized; use right-click > Open if Gatekeeper blocks them. Steam may need a restart to refresh shortcut artwork.

Download and extract your platform launcher permanently. The Windows archive includes the compatible launcher for Thunderstore first setup. Content mods continue to use the existing in-game marketplace.
