Calibre 8.13 Open-Source E-Book Manager Improves Library Export on Linux

Calibre 8.13 is a small update that only improves library export on Linux distros that mount /tmp in RAM by no longer using the /tmp directory when dealing with a large Full-Text Search (FTS) database, and improves virtual libraries by allowing users to define their search expressions more comfortably in a multi-line edit box.
