Version history

What changed in each released version. Installing a new version replaces the old one and keeps your licence.

1.208.0

September 16, 2026 · current version

The toolbar reads left to right in working order: the Overlay/Swipe toggle, then Revision clouds, Align, Zoom, Export, and Help.
The help panel walks the toolbar in the same order, with the whole-set check and Ignore colour explained under Revision clouds.
The cloud menu’s reopen row says what it does, Show results by sheet, with the count beneath it.

Windows 10 or 11 (64-bit). A licence is required to run it. On first launch Windows may show a “Windows protected your PC” notice because the app is newly published. Choose More info → Run anyway.

1.207.0

September 14, 2026

Results from checking a whole set stay available after you navigate. The cloud menu reopens the last check without re-scanning.
Revision clouds draw shallower scallops, closer to a hand-drawn cloud.
The Align menu is organised under two headings, with the Nudge and Superfine arrow sets labelled.
Ignore colour is an on/off switch.
The file pickers say Old drawing (shown in red) and New drawing (shown in blue), matching the view. Picked files no longer show invented version numbers or file dates.
A shorter help panel, and the update prompt says where the Download button goes.

1.206.0

September 14, 2026

A new application icon: two offset sheets in the overlay’s red and blue.
The welcome screen now says what to do. Select two PDF files to overlay and compare.
Change-cloud sensitivity is three levels instead of four. Normal is the expected setting, and Fine and Coarse are now clearly different from it.

1.130.1

August 12, 2026

First public build.
Update notifications, so the app can tell you a newer version exists.
Scale-aware measurement: calibrate a sheet once and place real dimensions.
An ignore-colour comparison mode for recoloured or re-plotted drawings.
