0.9.14 fixes one thing in the libraries setting from 0.9.13. Navidrome answers Library not found for a library id outside the account, and that one answer failed every call the mixes are built from, so a mistyped id left you with empty mixes and a log line about the server. The plugin now reads the account's libraries first, skips an id that is missing there and names it in the log, and builds the mixes from the rest. Nothing changes for an empty setting or for ids that exist.
