What's new in this version:
- Searching message bodies of messages in local folders, including filter and quick filter operations, not working reliably: Content not found in base64-encode message parts, non-ASCII text not found and false positives found.
- Defective messages (without at least one expected header) not shown in IMAP folders but shown on mobile devices
- Calendar: Unintended task deletion if numlock is enabled
- Various security fixes
