Reliability release for Thunderbird folder exports and difficult real-world data.
Changed
- Thunderbird-starred messages now convert to a yellow Star category instead of Outlook follow-up flags, keeping duplicated IMAP labels out of the To-Do list.
Fixed
- Folder exports now discover extensionless Thunderbird mbox files and nested
.sbdhierarchies, preview the full folder tree, and preserve it in the PST. - Malformed address books, pathologically large messages, duplicate or invalid folder names, contact-only configurations, and pathological recurrence data no longer abort otherwise valid conversions.
- Existing PST output is protected from accidental overwrite, and
maxSizeMBis capped safely at 50 GB. - Desktop scan and conversion processes now shut down cleanly with the app, and cancellation force-stops an unresponsive engine after a short grace period.
Security
- Updated the bundled SQLite library to 2.1.12, outside the affected
<= 2.1.11advisory range, and synchronized the third-party attribution ledger.
Verified with the full Windows/Linux/macOS CI matrix, independent PST-reader validation, a clean public-clone build, and an install/scan/launch/uninstall test of the Windows installer.
ContinuMail Converter is free software provided as is. Keep backups of the source mail and validate the PST and conversion report before relying on the output. These early installer and CLI builds are not code-signed, so Windows SmartScreen or macOS Gatekeeper may show a warning.
