AutoMixMaster Release 0.4.1

AutoMixMaster v0.4.1

Highlights

Improved release packaging workflow across supported platforms and architectures.
Fixed Linux CI Flatpak build failures by prefetching dependencies and using offline FetchContent source overrides in the Flatpak manifest.
Added workflow/README notes to document Flatpak dependency prefetch behavior.
Fixes
Windows Unicode path handling improvements in batch/render flows to avoid code page failures (e.g. “No mapping for the Unicode character exists in the target multi-byte code page.”).
Release creation step standardized with prebuilt create-github-release container usage.
Packaging & Docs
Updated build/install documentation (including macOS and universal build guidance).
Refined README structure and requirements clarity.
Notes
This is a stabilization and packaging reliability release focused on CI/release robustness and cross-platform path handling.
