What's Changed

  • Background uploads are now saved as WebP at quality 85, with a maximum longest edge of 2048 pixels and no upscaling. PNG, JPEG and WebP uploads are accepted.
  • Previously stored backgrounds, including the earlier normalized JPEG format, migrate once to WebP while preserving visibility and transparency preferences. Browser caches refresh for the new encoding.
  • SkiaSharp replaces the earlier image libraries. The permissively licensed native codec is bundled into every platform executable; no ImageMagick or separate runtime installation is required. Standalone Native AOT checks cover background migration and WebP uploads.

Release integrity

Native archives have matching platform-specific SPDX SBOM assets plus GitHub build-provenance and SBOM attestations. Installers and the built-in updater additionally verify a signed manifest and all packaged-file hashes.
