Bookdrop 2.2

Security

• Opening a crafted book can no longer write files outside Bookdrop's temp folder.
• A crafted book can no longer copy other files from your Mac into the converted output.
• PDF conversion renders books with scripts off, the browser sandbox on, and no network access. A book can load only its own files.
• HTML output blocks scripts and remote content from the book.

Fixed

• PDF bookmarks open the right chapter. Before, every chapter in one file opened that file's first page.
• PDF bookmarks work for books whose table of contents is in a subfolder.
• Books with spaces or other encoded characters in file names convert.
• Accented titles show correctly in PDF metadata, headers and footers.
• The cover in Word output fits the page.
• A failed or cancelled conversion no longer leaves a broken file, or deletes the file it was to replace.
• Temporary files are deleted when a book is closed. "Clear Temporary Files" keeps the book that is open.
• Batch conversion: a failed book no longer stays "converting", and Cancel All stops the book that is converting.
• Error messages name the real problem (password-protected PDF, DRM, scanned PDF) and tell you what to do.
• The notification names the real output format.

Changed

• Books open in the background, so the app stays responsive with large PDFs and Kindle files.
• Each book is read once, not twice, for the preview and the conversion.
• "Remember last output format" works.
• Removed two settings that did nothing: "Start chapters on new page" and "Open Logs Folder".
• PDF output is about 10 to 20% slower because of the new security checks.
