SLH v0.2.0

✨ SLH v0.2.0 — A new home for your Minecraft

This pre-release adds instance adaptation, a redesigned home screen and launcher optimizations. The full source code is available under GPL-3.0-only.

⚠️ Linux and macOS builds have not been manually tested. All four desktop targets were built and passed automated unit tests, but launching the app and Minecraft on Linux and macOS has not been verified. Please report problems with your OS version and CPU architecture.

🧩 Adapt an instance to another Minecraft version

• Create a copy of a Java instance for a different Minecraft release while keeping the original instance.
• Choose which folders and individual files to transfer, and leave out anything you do not need.
• Enable or disable compatible updates for mods, resource packs and shader packs, with choices per folder or file.
• Check recognized content against available compatible versions. If an update is unavailable or compatibility is unknown, choose to keep the file as-is, transfer it disabled (.off), or skip it.

Compatibility checks depend on the content source and available releases; adaptation does not guarantee that every mod or world will work on the selected Minecraft version.

🎮 A redesigned home screen

• Your player character takes center stage, with skin previews, interactive animations and rotation.
• Account controls, launcher status and the last played instance are available from the home screen.
• Switch between the new and classic home screens in appearance settings.
• Improved navigation highlighting, account-menu positioning and Play/Stop button consistency.

⚡ Launcher optimizations

• Reduced unnecessary 3D rendering and background work when the launcher is hidden or minimized.
• Improved scene cleanup and Windows WebView2 suspension and recovery.
• Cached skins and catalog results to avoid repeated loading when switching pages.

🚧 Bedrock Edition — W.I.P.

Bedrock support is still a work in progress. The Windows packages include the native helper, but the integration is experimental. Do not expect complete Bedrock support or feature parity across operating systems.

🛠️ Fixes and packaging

• Corrected data storage for installed and portable builds.
• Improved discovery of the bundled Bedrock helper.
• Fixed version comparison for launcher updates, including pre-release versions.
• Fixed platform-specific build and path-handling issues.
• Included third-party licenses in release packages.
