Release Notes 2025.0.1

Changelog

Added

• Function Lgsx_GetMigratedFieldGuid to return GUIDs of migrated fields Category, Label, TagIndex

Fixed

• Migration (automatically updates the database schema when opening files created with older software versions): Attachments now preserve their UUIDs and creation times, LinkRef in GeoTags correctly handles both external URLs and local references, and GeoTags modification times remain unchanged
• LgsxReaderExample (example application): Fixes related to non-ASCII characters handling

Other

• The Linux flavor of library no longer exports dependency symbols. This ensures a cleaner symbol table and prevents unintentional symbol exposure to avoid dependenies conflicts.

Additional Notes

Existing owners of LGS files will need to convert them to the LGSx format before opening or importing the LGSx content. The Leica LGS Converter Tool is available online (free of charge without any license).
