Latest Release Changelog (2.1.0)

Calibre Weblibrary Downloader 2.1.0 improves large-server scanning with metadata duplicate pre-checks, clearer per-book logging, server-count progress output, and more resilient server connection handling. It also hardens downloads and metadata parsing with safer filenames, malformed-response checks, fallback formats after size rejection, and a tolerant size guard for Calibre metadata mismatches.
