Release v2026.6.5

Therion Studio 2026.6.5

Highlights

• Added Mapiah background transform support for TH2 map editing, including transform metadata parsing, editing, undo/redo, and export-oriented metadata updates.
• Improved raster background rendering so image layers stay sharp while zooming instead of being limited by the initial display resolution.
• Hardened restored Mapiah raster backgrounds so metadata-backed layers ignore stale session scale, rotation, and position values.
• Simplified the Selection inspector layout around a single Options panel.
• Improved map rendering for inline line:subtype styling and point-label -align placement.
• Fixed template for New Project from Template.
• Fixed Smart Area so confirming a candidate returns the Selection inspector to the normal selected-object state instead of leaving a stale New Area panel behind.
• Fixed the Map inspector so selecting an object in Objects and switching back to Selection shows the symbol preview.

Known Limitations

• XTherion can open TH2 files with Mapiah rotated or scaled background metadata, but it does not display those transformed backgrounds. If such a file is edited and saved in XTherion, XTherion may rewrite many otherwise unchanged line objects, so users who care about tidy version-control diffs should prefer editing those files in Therion Studio or Mapiah.
