What's in 0.7.5

• Resize the Compare panes. Drag the bar between the two panes to make Hostfile or Live larger. Both sites stay visible and resize while you drag, and the bar shows the share of each pane. Each pane keeps at least a quarter of the width.
• Equal again with one click. As soon as the panes are not equal, a small button appears between the two pane bars. Click it, or double click the bar, and both panes are the same size again.
• Remembered. The position stays after closing Compare and after a restart.
• Keyboard. Tab to the bar and use the arrow keys to move it in steps of 5%. Escape while dragging puts the bar back where it was.
• Settings. New SolutionMAX logo. There is a GitHub button next to solutionmax.net, and Buy me a coffee is a proper button now. The three buttons stay on one row at every window size.
• The screenshots in the README are up to date again.

New: Windows

Dioptra is now available for Windows, with the same features as on macOS and Linux. The installer was added to this release on 5 October 2026.

• Run Dioptra-0.7.5-win-x64.exe. The installer is not signed yet, so Windows shows Windows protected your PC. Click More info and then Run anyway.
• Dioptra installs for your user only, without administrator rights, and starts when it is ready.
• Updates work from inside Dioptra, the same way as on the other platforms.

Updating

From 0.7.2 or later: open Updates, choose Download update and then Install and restart. Tabs and domain rules come back after the restart.

On macOS 0.7.0 and 0.7.1 cannot install an update themselves: download the zip once, quit Dioptra and replace the app in Applications (see the 0.7.2 notes).

Tested

Unit tests (70) pass on Linux and macOS. The browser, workspace, site and route bar tests pass on Linux. A new test drags the bar with a real mouse on Linux: live resize over both sites, Escape, the quarter limit, saving on release, the reset button and double click. The packaged Apple silicon build passes the workspace test, and so does the packaged Intel build of this code under Rosetta. The official 0.7.4 Apple silicon build was started on a Mac and updated itself to 0.7.5 from this release: download, install, restart, signature valid. The drag test with a real mouse does not run on macOS, and nothing was tested on real Intel hardware.

Windows: tested on Windows 11 in a virtual machine. Installing through the SmartScreen prompt, the unit tests (70) and the workspace, site and route bar tests against the installed app pass, and dragging the bar between the Compare panes works with a real mouse. An older-labelled build of the same code updated itself to 0.7.5 and restarted. The Claude extension installs and loads; signing in was not tested. Not tested on Windows 10 or on real hardware.
