• #393, #438, #560: Optionally dump "all" PostgreSQL/MySQL databases to separate files instead of one
  combined dump file, allowing more convenient restores of individual databases. You can enable
  this by specifying the database dump "format" option when the database is named "all".
• #602: Fix logs that interfere with JSON output by making warnings go to stderr instead of stdout.
• #622: Fix traceback when include merging configuration files on ARM64.
• #629: Skip warning about excluded special files when no special files have been excluded.
• #630: Add configuration options for database command customization: "list_options",
  "restore_options", and "analyze_options" for PostgreSQL, "restore_options" for MySQL, and
  "restore_options" for MongoDB.
