lemonade-sdk/lemonade v10.10.0 on GitHub

Headline

Audio generation arrives with the ThinkSound sound-effects and ACE-Step music backends, a new POST /v1/audio/generations endpoint, and a GUI audio-generation panel.
System-installed ROCm is now reused on Windows as well as Linux, and the experimental vLLM ROCm backend reliably targets AMD GPUs on hybrid AMD/NVIDIA hosts.
A suspend inhibitor keeps the machine awake while inference is running on Linux (systemd-logind), enabled by default and opt-out.
A new GET /v1/models/{id}/files endpoint reports each model's resolved local files for the GUI Files tab, with absolute paths gated behind an opt-in include_paths=true.

Breaking Changes

The experimental ROCm vLLM backend now requires a writable $XDG_RUNTIME_DIR; launch fails if one cannot be created, which may affect minimal or container setups.
After the Debian/Ubuntu package upgrade migration runs, re-enable the per-user service manually with systemctl --user enable lemond.
