Changelog

1.2.0 - 2026-07-14

• Added on-demand scanning for existing PDF attachments.
• Added automatic duplicate checks for newly added PDFs.
• Used Zotero's stored MD5 as a candidate index and SHA-256 as the final duplicate criterion.
• Kept hashing responsive with asynchronous 1 MiB reads and per-read timeouts.
• Fixed an empty-queue loop that could block the Zotero main thread.
• Fixed historical scans failing on relative storage: attachment paths.
• Recovered uniquely identifiable PDFs renamed by external attachment tools.
• Added concise scan summaries and a duplicate-removal confirmation dialog.
• Converted the interface, logs, metadata, and documentation to English.
