Version 1.2.0

Released August 23, 2026.

An update with two new features, one enhancement, and one bug fix.

All changes

• New feature Native .tatin file format: save your project as a native PageTatin file with the new Save as… button in the top bar. .json remains available as Export as JSON for backwards compatibility.
• New feature Duplicate pages: select one page or several, then duplicate them from the right-click menu or via Edit → Duplicate. The copies are inserted directly after your selection. You can also hold Option/Alt while dragging a page to drop a copy where you want it.
• Enhancement Export wording is now consistent for .pdf: the menu command, dialog, and confirmation button all say Export (previously Save).
• Bug fix Opening a different flatplan no longer overwrites the active one without warning when it hasn’t been saved to a file yet. PageTatin now warns you first and gives you the chance to save.
