Keep TV specials when a request covers only regular seasons. Encode first-run passwords, default missing config-show fields, and strip Windows CRLF on Python, Dockerfiles, and migrations. Pin express-stack images. After Sonarr title delete, remove leftover torrents/ dirs even when qB already dropped the torrent. Document that only the default stack is supported.
