calibre 6.0

New Features​

  • For details on the major changes in calibre between 6.0 and 5.0, see calibre - New in calibre 6.0
  • Full text search: You can now search the entire text of all books in your calibre library
  • Support for new CPU architectures: Apple Silicon and ARM64 on Linux. Support for 32bit CPUs has been dropped because Qt 6 does not support them
  • Dark mode in calibre is now controlled via a setting in Preferences->Look & feel rather than an environment variable
